Thyristor Rectifiers: An In-Depth Overview

Thyristor rectifiers are pivotal in the realm of power electronics, providing crucial capabilities for converting alternating current (AC) to direct current (DC). These devices, integral to many industrial and commercial applications, harness the unique properties of thyristors to deliver efficient and controlled power conversion. This article explores the core concepts, advantages, and applications of thyristor rectifiers, offering a comprehensive understanding of their role in modern power systems.

What is a Thyristor Rectifier?

A thyristor rectifier is a type of rectifier circuit that utilizes thyristors—semiconductor devices known for their ability to handle high voltages and currents. Unlike traditional diodes, thyristors can be controlled and turned on or off by applying a gate signal, which allows for precise regulation of power.

How Thyristor Rectifiers Work

AC Input: The thyristor rectifier receives an alternating current input, which alternates between positive and negative phases.

Thyristor Operation: A thyristor is a four-layer, three-junction device with four terminals: anode, cathode, gate, and a small gate terminal for triggering. During the positive half-cycle of the AC input, the thyristor can be triggered into conduction by a gate pulse. Once triggered, it remains in the conducting state until the AC input goes through a zero-crossing point.

Rectification: As the AC input varies, the thyristors alternate between conducting and blocking states, effectively converting the AC into a pulsating DC output. The output DC voltage is controlled by adjusting the firing angle of the thyristors, which determines when during each cycle the thyristor will conduct.

Controlled Firing: The timing of the gate pulses—referred to as the firing angle—is crucial. By varying this angle, the average DC output voltage can be controlled, allowing for dynamic power regulation.

Benefits of Thyristor Rectifiers

Thyristor rectifiers offer several significant advantages:

High Power Handling: Thyristors are designed to handle high voltages and currents, making them suitable for demanding applications.

Precise Control: The ability to control the firing angle allows for precise adjustment of the DC output voltage, which is essential for applications requiring variable power.

Efficiency: Thyristor rectifiers provide efficient power conversion with minimal energy losses, improving overall system performance.

Durability: Thyristors are robust and reliable, capable of withstanding harsh operational environments and high power levels.

Applications of Thyristor Rectifiers

Thyristor rectifiers find applications across various sectors:

Industrial Motor Drives: Thyristor rectifiers are used to control the speed and torque of electric motors in industrial settings, enabling precise motor control.

HVDC Transmission Systems: In high-voltage direct current (HVDC) systems, thyristor rectifiers convert AC power into DC for long-distance transmission, reducing losses and improving efficiency.

Power Supplies: Thyristor rectifiers are employed in power supply units to convert AC from the grid into stable DC for electronic devices and systems.

Battery Charging: They are used in battery chargers to regulate the charging current, ensuring efficient and safe charging of batteries.

Welding Equipment: Thyristor rectifiers provide the controlled DC necessary for electric arc welding, ensuring consistent welding quality and performance.

Challenges and Considerations

Despite their advantages, thyristor rectifiers present certain challenges:

Complex Control Systems: The precise control of firing angles and synchronization with the AC supply can be complex and requires sophisticated control circuitry.

Thermal Management: High-power applications can generate significant heat, necessitating effective cooling and thermal management to maintain reliable operation.

Harmonic Distortion: Thyristor rectifiers can introduce harmonic distortions into the power system, which may require additional filtering to mitigate.

Conclusion

Thyristor rectifiers are crucial components in modern power systems, offering efficient and controlled conversion of AC to DC. Their ability to handle high power levels, coupled with precise control capabilities, makes them invaluable in industrial motor drives, HVDC systems, power supplies, and more. As technology advances, ongoing improvements in thyristor rectifiers are likely to enhance their efficiency and applicability, solidifying their role in the future of power electronics.

[sngl-led-auto-lights]

 LED auto lights refer to the use of LED technology for both internal and external lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load tests. LED auto lights can be widely used to create an in-car environment with a service life of 50,000 hours. The structure of LED is sturdy and not easily affected by vibration, and the light output brightness will not drop significantly during use. LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, taillights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights.

Advantages:

1. Energy saving: The light-emitting diode directly converts electrical energy into light energy, and the power consumption is only 1/10 of that of ordinary car bulbs, which can better save fuel consumption and protect the car circuit from being burned out by excessive load current.

2. Environmental protection: There is no ultraviolet and infrared in the spectrum, low heat, no radiation, low glare, and the waste can be recycled, no pollution, no mercury, safe to touch, and it is a typical green lighting LED source.

3. Long life: There is no loose part in the lamp body, and there are no shortcomings such as easy burning of filament light, heat deposition, and light decay. Under the appropriate current and voltage, the service life can reach 80,000-100,000 hours, which is more than 10 times longer than the life of traditional light sources. (It has the characteristics of one-time replacement and lifelong use)

4. High brightness and high temperature resistance. (Electric energy is directly converted into light energy, low heat, and can be touched by hand, safe and secure)

5. Small size. The designer can change the lamp mode at will to diversify the car shape. The reason why automobile manufacturers favor LED is entirely determined by the advantages of LED itself.

6. Good stability and strong anti-seismic performance of LED: resin encapsulation, not easy to break, easy to store and transport.

7. High luminous purity, clear and bright colors, no need for lampshade filtering, and light wave error within 10 nanometers.

8. Fast response speed, no hot start time required, can emit light within microseconds, while traditional glass bulbs have a 0.3 second delay, which can prevent rear-end collisions and ensure driving safety.

Disadvantages:

1: LED headlights are more expensive than ordinary headlights. (With the continuous popularization of LED applications, prices will be further reduced)

2: It is difficult to popularize car headlights, and the heat dissipation is not good. If the heat dissipation is not properly handled, it is easy to light decay, which affects the service life of the headlights.

3: There are no industry standards issued, and the product quality is uneven. The price of the same product produced with different LEDs varies by 1-2 times. Fortunately, a small number of companies implement standards higher than the general industry standards, so product quality control is better than most companies, such as SNGL brand companies, etc.

Review, teardown, and testing of RSP-320-24 Mean Well power supply

The RSP-320-24 is a 24-volt power supply with a maximum current of 13.4 amps. The supported mains voltage is from 100 to 240 volts without an additional switch. The supply measures 8.5 × 4.5 × 1¼ inches (215 × 115 × 30 millimeters), made on a printed circuit board fixed to the base's case. The top cover is perforated at the back near the connection terminals and on the front, where the cooling fan is installed. The fan starts spinning even if there's no electrical load. As the load increases, the fan speeds up, following the load current value. The fan sucks in the air and pushes it through the internal case volume to the perforated holes, including those on the side walls.

The input and output circuits are connected to a standard screw terminal block (1), from right to left: 3 terminals for the input line, neutral and ground wires, and 3 in parallel for common and +24V output. The input voltage from the terminals goes to the fuse (2), then to the pulse limiter (varistor), followed by the RF interference filter (3), and finally to the diode bridge (5). Next comes the active PFC, controlled by the PFC+PWM controller FAN4800 (4). Indeed, with a 234-volt AC power input, we get a rectified voltage on the storage capacitor (8) of 377 volts, approximately 47 volts more than without PFC Boost. The small voltage reserve is confusing since the capacitor installed is rated for 180 uF and 400 volts. All that's left is to rely on Nichicon's quality control.

The power part of the PFC is made of two parallel MOSFETs, IPP60R280P6 (7) and on an ultrafast diode 8A 600V STTH8S06D (6). The temperature sensor (11) is mounted above the PFC elements. The output voltage from the PFC is supplied to the two-transistor forward converter; the transistors are IPP60R280P6 (9) and are controlled by the same FAN4800 controller. The transformer (10) converter voltage is rectified and supplied to the LC filter. The output rectifier comprises eight diodes connected in two parallel groups (12). Total output capacitance: 2 pieces of 1000uF, 35V, designed for operating temperatures up to 220°F (105°C) (13). The output high-current circuits are reinforced with tinned copper busbars.

The control signal from the high-voltage side to the low-voltage side is transmitted through transistor optocouplers (there are two of them in the photo above the transformer hidden under a blob of the compound). One optocoupler is the primary regulation channel, and the second forms a backup channel for overvoltage protection, OVP.

The block diagram in the datasheet shows the "Active Inrush Current Limiting" node. Still, we could not find components on the board that could perform such a role. Still, the inrush current limitation element is present, marked as RTH1 on the board, and installed near the boost inductor PFC; most likely, this is an ordinary NTC.

The high-voltage part of the board, starting with the capacitor (8) and ending with the transformer leads (10), is coated on the high-voltage side with a protective composite, presumably epoxy-based, which further increases electrical safety.

There is additional insulation and a thin sheet of fiberglass between the aluminum case and the board (solder side).

The overall build quality is good.

Test conditions

Most tests use metering circuit #1 (see appendices) at 80°F (27°C), 70% relative humidity, and 29.8 inHg pressure. The measurements were performed without preheating the power supply with a short-term load unless mentioned otherwise.

The following values were used to determine the load level:

Output voltage under a constant load

The high stability of the output voltage should be noted.

Power-on parameters

Powering on at 100% load

The power supply is turned off at least 5 minutes before the test, with a 100% load connected. The oscillogram of switching to a 100% load is shown below (channel 1 is the output voltage, and channel 2 is the current consumption from the grid):

The picture shows three distinguishable phases of the power-on process:

The pulse of the input current charging the input capacitors when connected to the grid has an amplitude of about 2 A and a duration north of the mains voltage period.

Waiting for the power supply control circuit to start for about 300 ms.

(Output Voltage Rise Time) Starting the converter, increasing the output voltage, and entering the operating mode takes 8 ms.

(Turn On Delay Time) The entire process of entering the operating mode from the moment of powering on is 315 ms.

(Output Voltage Overshoot) The switching process is aperiodic; there is no overshoot.

Powering on at 0% load

The power supply is turned off at least 5 minutes before the test, with a 100% load connected. Then, the load is disconnected, and the power supply is switched on. The oscillogram of switching to a 0% load is shown below:

The picture shows three distinguishable phases of the power-on process:

The pulse of the input current charging the input capacitors when connected to the grid has an amplitude of about 2.2 A and a duration slightly longer than one mains period.

Waiting for the power supply control circuit to start for about 300 ms.

(Output Voltage Rise Time) Starting the converter, increasing the output voltage, and entering the operating mode takes 7 ms.

(Turn On Delay Time) The entire process of entering the operating mode from the moment of powering on is 320 ms.

(Output Voltage Overshoot) The switching process is aperiodic; there is no overshoot.

Power-off parameters

The power supply was turned off at 100% load, and the input voltage was nominal at the moment of powering off. The oscillogram of the shutdown process is shown below:

The picture shows two phases of the shutdown process:

(Shutdown Hold-Up Time) The power supply continues to operate due to the input capacitors holding charge until the voltage across them drops to a certain critical level, at which maintaining the output voltage at the nominal level becomes impossible. The phase takes 14 ms.

(Output Voltage Fall Time) Reduction of the output voltage, stopping voltage conversion, and accelerating the voltage drop takes 18 ms.

(Output Voltage Undershoot) The shutdown process is aperiodic; there is no overshoot.

Right before shutdown, the current waveform at 100% load is close to sinusoidal with an amplitude of 4.22 A.

Ripple output voltage

100% load

At 100% load, the low-frequency ripple is approximately 3 mV.

At 100% load, the ripple at the converter frequency is approximately 50 mVp-p, and the noise is 120 mVp-p.

75% load

At 75% load, the low-frequency ripple is approximately 3 mV.

At 75% load, the ripple at the converter frequency is approximately 40 mVp-p, and the noise is 120 mVp-p.

50% load

At a 50% load, the low-frequency ripple is approximately 3 mV.

At 50% load, the ripple at the converter frequency is approximately 30 mVp-p, and the noise is 70 mVp-p.

10% load

At 10% load, the low-frequency ripple is approximately 2 mV.

At a 10% load, the ripple at the converter frequency is approximately 20 mVp-p, and the noise is 90 mVp-p.

0% load

No-load current consumption measured with a multimeter: 53.5 mA.

(Power Consumption) The first assumption of excessive standby power draw of more than 6.5 watts is wrong since the current in this mode is predominantly reactive. Indeed, the input filter in the circuit contains two capacitors with a combined capacitance of 1.5 μF. Measuring the exact active power consumption at a 0% load with a basic set of instruments (oscilloscope, multimeter, etc.) is impossible.

At 10% load, the low-frequency ripple is approximately 2 mV.

At 10% load, ripples at the converter frequency are masked by the 90 mVp-p noise.

Dynamic characteristics

TA mode with periodic switching between 50% and 100% load was used to evaluate the dynamic characteristics. The process oscillogram is shown below:

It is evident that the supply’s response to loading changes is close to aperiodic, and there is no overshoot, which indicates a good stability margin. The magnitude of the response to load changes is just 60 mV.

Overload protection

The claimed protection type is "hiccup mode, recovers automatically after fault condition is removed." This was confirmed during testing. When a short circuit occurs, the power supply periodically tries to turn back on and, if the overload is still present, turns off again until the next attempt. This operating mode reduces energy losses and heating during overload. Still, it does not allow the parallel connection of multiple power supplies with a common output.

The output current for the overload protection to kick in is 17 A.

Input circuit safety assessment

(Input discharge) Safety assessment is based on the discharge time constant of the input circuits when disconnected from the grid; the value is 0.26 s. This means that when operating on a 120 V input voltage, the time required to discharge the input circuits to safe values (<42 V) will be 0.41 s:

Important: The result is valid for this particular power supply unit; it was obtained for testing purposes and should not be taken as a safety guarantee.

The leakage current at the ground pin is less than 10 µA.

Thermal conditions

When operating with no load connected, no component overheating had been noticed. Thermograms were captured at three power levels: 80, 90, and 100%, fully assembled and with the lid removed. Thermal images show that the most loaded element of the block is the input diode bridge, and its heating seriously stands out against the background of all the other components.

Unfortunately, already at 80% load, the diode bridge heats up to an unacceptable level of 259°F (126°C), which is dangerous for long-term operation.

80% load

90% load

100% load

Conclusions

Overall, the RSP-320-24 is well-built: this power supply has good dynamic characteristics, low noise, and ripple, good accuracy in maintaining the output voltage, and is well put together. The load should be limited to 70–80% of the nominal for long-term operation.

Important: The results are valid for this particular power supply unit; they were obtained for testing purposes and should not be used to evaluate all the units of the same type.

How Is The Broadband Light Source Moving Spectroscopy to UV From Near-IR?

Discharge lamps, dye lasers, and optical parametric oscillators were the only valuable sources for spectroscopy in the early 1990s or mid-1980s. However, as optical technologies evolve and their applications broaden, we have been introduced to new light sources and lasers. The broadband light source is one such type of light source that has gained popularity in optical spectroscopy.

In this blog post, we will look at what a broadband light source is, how it works, and how it opens up new opportunities for spectroscopists. So, without further ado, let's begin with a definition of a broadband light source.

What Exactly Is A Broadband Light Source?

A broadband light source, also known as a superluminescent source, is a superluminescent diode with a wavelength of emission of 700 nm and a bandwidth of 1700 nm that is perfect for OEM integration. Moreover, it is often used for multi-wavelength tests for measuring wavelength-division-multiplexing components. This implies it has a wide range of applications in the medical, telecommunications, sensing, and measurement industries.

Broadband light sources are utilized for ultrahigh-resolution optical coherence tomography, passive component testing, and multi-channel fiber Bragg grating interrogation, in addition to these applications. Now, let's take a closer look at how a broadband light source works.

Working Principle of Broadband Light Source

The working principle of a BLS is very simple. A prism or grating disperses a beam of radiation from a broadband source. The scattered radiation strikes a slit, through which a small range of wavelengths passes to reach a detector. By rotating the prism or grating, consecutive wavelengths are brought onto the slit, allowing the spectrum to be scanned.

Moreover, broadband light sources are a great pick for Near-Infrared (NI) spectroscopy due to several factors. The following are three of BLS's most notable characteristics.

A. The broadband light source's directional output enables substantially better levels of light transmission efficiency into the fiber optic cable.

B. Broadband light sources have an extremely limited spectral bandwidth because they generate coherent light, allowing them to transport data at significantly greater speeds.

C. Broadband light sources are frequently modulated directly. This is a simple and effective method of converting data to an optical signal.

Eventually, these exceptional properties play a critical role in making BLS a viable option for spectroscopy and optical fiber communication applications. Let us now proceed to the next section of this blog to learn how broadband light sources provide new opportunities for spectroscopists.

How Broadband Light Source Brings New Opportunities For Spectroscopists?

Broadband light was previously only available from discharge lamps, plasma sources, hot glow bars, or the sun for much of the last decades. Also, before the laser, one of the only ways to obtain narrowband line radiation was to utilize a low-pressure gas discharge lamp, such as a mercury or sodium lamp.

However, a new generation of comparatively robust sources, such as Supercontinuum lasers, laser-driven plasma sources, and high brightness LEDs, are finding a place in the spectroscopist's toolset.

The outstanding qualities of these broadband light sources help in the advancement and efficiency of spectroscopy. This technology is not only more advanced than traditional light sources, but it is also less expensive. All of these novel light sources are enhancing spectroscopy from the near-IR to the UV.

Moreover, based on the research and improvements being conducted on broadband light sources, we can confidently predict that we are yet to witness substantial growth in industrial applications of broadband light sources in the near future.

Design A High Performance PON Optical Receiver

An optical receiver's structure is very simple. It consists of a photodiode that produces the electric current and an amplifier. It is much more difficult to create a high-performance optical receiver. We will now discuss some criteria for actual receivers.

There are many factors that go into the process. Signal current noise, noise coming from the photodiode (such as an avalanche dimming diode), noise from the amplifier electronics, thermal noise and dark current are all important factors.

How do you choose the right photodiode

For optical receiver applications, there are two main types of photodiodes: Avalanche and PIN.

Photodiode PIN

PIN photodiode can be extended to PN diode. But PN diode is not without its flaws. The PN diode's depletion area is too small, so the received PON Optical Receiver power must not be very high in order to generate enough current. The second flaw of PN diode is its slow response, which limits it to kilohertz applications.

These limitations were solved by PIN photodiode. The depletion area has been increased to the maximum extent possible, with most photons being absorbed in the depletion area. The intrinsic layer reduces the function capability, which increases the switching speed and photon capture area.

This improved design has the added benefit of a faster opto-electro conversion rate and more efficiency.

Avalanche photodiode

Each photon absorbed by a PIN photodiode produces an electron hole pair, which then sets one electron flowing in the circuit.

A few incident photons can result in many carriers being created and an increase in external current in Avalanche photodiodes. This is how an Avalanche photodiode does it.

This phenomenon is called avalanche multiplication. This is because a strong electric field accelerates current carriers to such an extent that they knock out valence electrons from the semiconductor lattice. With a sufficient bias voltage, an avalanche will occur.

All of these are great, but there is a downside. The carriers amplify, but the uneven nature and multiplication creates noise.

Avalanche photodiodes, while non-linear, are quite unstable. However, they perform very similarly to regular silicon photodiodes, except that they require a lower operating voltage to achieve good multiplication.

Other important performance parameters for a photodiode

Below are some key parameters for your reference.

Receptivity

Photodiode responsiveness is the ratio between incident light power and generated current. This is often expressed in Amp/Watt. This is sometimes referred to as quantum efficiency.

Dark Current

The photodiode produces dark current when there is no incident sunlight. Dark current also includes current that is generated by background radiation or the saturation current at the semiconductor junction. When used in optical communication systems, dark current can be a source for noise. Read more here: https://www.premlink.net/pl150d-3-ftth-optical-receiver-pon-pass/

Product structure of LCD (1)

https://www.topfoison.net/lcd/product-structure-of-lcd-1/

1. According to the technical classification of display screen: tft-lcd /Mono LCD(stn-fstn)/OLEDLCD:(Liquid Crystal Display)

Liquid Crystal Display (LCD) is short for Liquid Crystal Display (Liquid Crystal Display). The structure of LCD is to place Liquid Crystal in two parallel glass pieces. There are many thin vertical and horizontal wires between the two pieces of glass.The structure of the LCD is placed in the middle of the two pieces of parallel glass liquid crystal box, the substrate glass set on TFT (thin film transistor), set the color filter substrate glass on, on the TFT signal and the voltage change to control the rotation direction of the liquid crystal molecules, so as to achieve control of each pixel display emergent polarized light or not and to achieve.Create various colors based on white light passing through a color filter.The white light will form basic colors such as red, green and blue after passing through, and the light transmittance of each pixel point will be controlled by an electric current, so as to control the color of the pixel.

TFT-LCD

OLED

The OLED, the full name of the Organic Light Emitting Diodes, will emit Light per pixel without the need for a separate backlight or color filter.Each OLED pixel can be assigned red, green and blue, and now some manufacturers have added yellow, but the principle is the same.

OLED is divided into AMOLED and PMOLED

The AMOLED(Active matrix organic light-emitting diode) is a display technology.AM (active matrix body or active matrix body) refers to the pixel addressing technology behind.At present, AMOLED technology is mainly used in smart phones, and continues to develop towards the direction of low power consumption, low cost and large size.

AMOLED has the advantages of self-illumination, wide viewing Angle, high contrast and fast reaction speed.AMOLED has a higher refresh rate and significantly lower energy consumption than passive OLED.This makes AMOLED ideal for power-sensitive portable electronic devices.

Disadvantages: due to the relative immaturity of the manufacturing process, the yield and the relatively mature IPS panel are still relatively low and the cost is relatively high.Because of its small size and short life span, AMOLED is currently only widely used in smartphones and smartwatches that are fast and use only small displays.

The Passive matrix organic light-emitting diode (PMOLED) is the emitting light emitting diode.PMOLED is like STN LCD and AMOLED is like TFT LCD.PMOLED simply forms a matrix of cathodes and anodes, and lights up the pixels in the array in a scanning manner. Each pixel is operated in a short pulse mode to produce instantaneous high-brightness luminescence.

The advantages are simple structure, can effectively reduce the manufacturing cost, but high driving voltage, make PMOLED is not suitable for the application of large size and high resolution panel, with the current development.

Disadvantages: it is not suitable for displaying dynamic images, and its response speed is relatively slow, making it difficult to realize large size. In order to maintain the brightness of the whole panel, it is necessary to increase the brightness of each Pixel and increase the operating current, thus reducing the life of OLED Device.Current Drive is not easy to control.However, because the process is relatively simple, simple structure, relatively energy saving.

At present, the OLED screen we touch, whether it is a smart phone or OLED TV used in the panel is also AMOLED screen.

OLED vs. LCD:Contrast: OLED wins

Contrast refers to the difference between the brightest white and darkest black, while LCD has an advantage in brightness (especially in HDR mode) and OLED has the darkest black.In general, OLED displays tend to have higher contrast because the advantage at the black level magnifies the difference.

Perspective: OLED wins

Most LCD screens don’t perform as well as IPS (especially TVS and smartphones), so with the exception of the top IPS displays, LCD panels tend to perform slightly worse than OLED displays in terms of viewing angles.In front of an OLED TV, the viewer can see the content on the screen with a high-quality experience, regardless of which Angle they are sitting at.

Gamut: OLED winsBrightness level: LCD wins

Because LCD TVS typically use a separate backlight, they generally provide better brightness.In reality, the best LCDS and oleds have a brightness gap of about 400NIT, and overall LCDS are superior in brightness levels.

Color uniformity: OLED wins

The ability to display colors in a uniform way on a flat surface is a very important indicator.Well, since the backlight of the LCD screen usually comes from the edge, the uniformity of illumination is relatively general.If the backlight is evenly scattered behind the screen, then the discrete backlight can bring better effect.Oleds, on the other hand, are much better at this, since each pixel emits its own light, so there is no need for the light source to diffuse.In real life, even OLED displays are not completely uniform, and even flexible OLED displays appear, but they are still superior to LCD in general.

Power consumption: LCD wins

At the same brightness level, LCDS use less energy than oleds.For mobile devices, higher brightness means better visibility outdoors. On the other hand, OLED panels use more power depending on how many pixels there are, so higher resolution OLED screens use more power.

Cost efficiency: LCD wins

At the moment, LCDS are the cheapest way to display, but OLED technology is improving over time.

Summary: OLED is the best, but it still needs to be developed

Overall, OLED has won a big battle in the parameter comparison of image quality, so the future can be said to be a future development trend.But OLED is still limited by production costs and size bottlenecks.Oleds outperform LCDS in most display parameters unless you have specific requirements for brightness.But cost is also a consideration. Smartphones are ok. For a display device as large as a TV, oleds can cost several times as much as LCDS.

Drawbacks and merits of optical fiber transmission

According to the Global News Agency, the global optical fiber transmission market was worth about $2.75 billion in 2016 and is expected to reach about $3.72 billion in 2012. These statistics show that fiber optic transmission is in its prime and will dramatically change telecommunications. Drawbacks and merits of optical fiber transmission will be discussed in this article.

Optical fiber transmission is becoming more and more common in modern society, driven by the growing demand for higher bandwidth and faster connections for various industrial and residential uses. In this tutorial, the advantages and disadvantages of fiber optic transmission will be explored in detail.

Optical fiber transmission technology

Typically, an optical fiber transmission communication system consists of three main components: an optical transmitter, an optical cable, and an optical receiver. The optical transmitter converts the electrical signal into an optical signal; the optical cable transmits the optical signal from the optical transmitter to the optical receiver, and the optical receiver reconverts the optical signal into an electrical signal. The most commonly used light emitters are semiconductor devices such as LEDs (Light Emitting Diodes) and laser diodes. Photodetectors are key components of light receivers. It uses the photodetector effect to convert light into electricity. As for fiber optic cables, that's too much.

With the use and demand for speed and bandwidth, the evolution of fiber optic cables has been phenomenal. Now there are OS2 fiber, OM1 fiber, OM2 fiber, OM3 fiber, OM4 fiber and OM5 fiber cable for different optical applications in the optical cable market. Optical fiber is used as a medium for telecommunications and networking because it is flexible and can be bundled into cables. It's especially beneficial for long-distance communications because light travels through fiber with little attenuation compared to copper cables. The diagram below shows that all fiber optic transmission systems use modulated light to transmit information from a transmitter to a companion receiver.

Advantages of Fiber Optic Transmission

Optical fiber transmission has largely replaced copper wire communications in the core networks of the developed world because it is superior to electrical transmission. The following are the main advantages of fiber optic transmission.

Extremely high bandwidth: No other cable-based data transmission medium offers the bandwidth that fiber optics can. The amount of data transmitted by an optical cable per unit time is much larger than that of a copper cable.

Longer distances: In fiber optic transmission, fiber optic cables provide low power loss, which allows signals to travel longer distances than copper cables.

Anti-electromagnetic interference: In actual cable deployment, it is inevitable to encounter interference sources in industrial environments such as substations, heating, and ventilation. However, fiber has a very low bit error rate (10 EXP-13) because fiber is highly resistant to electromagnetic interference. Optical fiber transmission is almost noise-free.

Low Security Risk: The growth of the optical fiber communication market is mainly due to the increasing awareness of data security issues and the use of alternative raw materials. Data or signals are transmitted by light in fiber optic transmission. Therefore, there is no way to detect the data being transmitted by "listening" to the electromagnetic energy "leaking" through the cable, thus guaranteeing the absolute security of the information.

Small size: The diameter of fiber optic cables is very small. For example, the wire diameter of a single OM3 multimode fiber is about 2mm, which is smaller than that of coaxial copper cables. Small size, save more space in fiber transmission.

Lightweight: Fiber optic cables are made of glass or plastic and are thinner than copper cables. These make them lighter and easier to install. Easy adaptation to increasing bandwidth: By using fiber optic cables, new equipment can be added to existing cable infrastructure. Because the fiber optic cable can provide much larger capacity than the original laying fiber optic cable. And WDM (wavelength division multiplexing) technologies, including CWDM and DWDM, enable fiber optic cables to accommodate more bandwidth.

Disadvantages of Fiber Optic Transmission

Although optical fiber transmission brings a lot of convenience, its shortcomings cannot be ignored.

Fragility: Usually fiber optic cables are made of glass, which makes them more fragile than wires. Additionally, glass is affected by various chemicals, including hydrogen (a problem in underwater cables), so it needs to be more careful when deployed underground.

Installation Difficulty: The splicing of fiber optic cables is not easy. If you bend them too much, they will break. And the optical cable is easily cut or damaged during installation or construction. All of these make installation difficult.

Attenuation & Dispersion : As the transmission distance increases, the light is attenuated and dispersed, which requires adding additional optical components such as EDFA.

Costs higher than copper: Even though fiber installation costs have dropped by as much as 60 percent annually, installing fiber optic cables is still relatively higher than copper cabling. Because copper cable installation does not require as much care as fiber optic cables. However, fiber is still entering the local loop and enabling broadband access to users and end users through technologies such as FTTx (Fiber to the Home, Premises, etc.) and PON (Passive Optical Network).

Special equipment is often required: In order to ensure the quality of optical fiber transmission, some special equipment is required. For example, most fiber endpoints require equipment such as an OTDR (Optical Time Domain Reflectometer), and require expensive specialized optical test equipment such as optical probes and power meters to properly provide fiber testing.

Conclusion of optical fiber transmission

Optical fiber transmission is widely used for data transmission and is increasingly used instead of metal wires due to its high efficiency and large transmission capacity. We have already seen fiber optic cables have replaced traditional copper twisted pair or coaxial cables. With the use and demand for large bandwidth and fast speed, fiber optic transmission will undoubtedly bring more opportunities, and will continue to be researched and expanded to meet future needs.

input of this comparator allows a larger common

Output delay time: Including the transmission delay of the signal through the components and the rise time and fall time of the signal. Need to pay attention to the influence of different factors on the delay time when designing, including the influence of temperature, capacitive load, input overdrive, and so on.3ns. Drain-source voltage: Because the comparator has only two different output states (zero level or power supply voltage), and the output stage with full power swing characteristics is an emitter follower, which makes its input and output signal. When the potential level of the low-level signal is lower than a certain predetermined value VL, it is equivalent to the negative saturation output of the comparator circuit. The maximum bias current of the MAX917 series of comparators is only 2nA. Bias current (Ibias) is defined as the median of the input currents of the two comparators and is used to measure the effect of input impedance. The two inputs of the comparator are analog signals, and the output is a binary signal 0 or 1. 

For high-speed comparators, such as MAX961, the typical value of the delay time can reach 4. When the difference of the input voltage increases or decreases and the sign of the positive and negative remains unchanged, the output remains constant. LM339 and LM393 have the characteristics of swift switching, short delay time, which can be used in voltage comparison. It is beneficial for you to learn detailed information on theLM339D . When the input voltage VI&62;VT&39;, the output is a negative saturation voltage, and VT&39; is called the lower threshold (trigger) level..5ns and the rise time is 2. The comparator has two thresholds, and the transmission characteristic curve is window-shaped. There is only a very small pressure difference. Classification Zero-crossing voltage comparator Voltage comparator: Changing an input terminal of the zero-crossing comparator from the ground to a fixed voltage value. This China Terminal Blocks Manufacturers voltage difference depends on the emitter junction voltage in the saturation state of the internal transistor, which corresponds to the drain-source voltage of the MOSFFET.

Comparing two or more data items to determine whether they are equal, or determining the size relationship and arrangement order between them is called comparison. Superpower swing: In order to further optimize the operating voltage range of the comparator, Maxim uses the parallel structure of the NPN tube and the PNP tube as the input stage of the comparator, so that the input voltage of the comparator can be expanded so that the lower limit can be lower To the lowest level, the upper limit is 250mV higher than the power supply voltage, thus reaching the Beyond-theRail standard. The input of this comparator allows a larger common-mode voltage. The comparator is a circuit that compares an analog voltage signal with a reference voltage. 

There is a current at the input end that flows through the internal resistance of the signal source and flows into the comparator. Performance Bias current: The input impedance of the ideal comparator is infinite, so theoretically, it has no effect on the input signal, but the input impedance of the actual comparator cannot be infinite. Hysteresis comparator: Lead a resistor divider branch from the output to the non-inverting input. The commonly used chips have LM324, LM358, uA741, TL081234, OP07, OP27. Internal, which creates an additional pressure difference. When the input voltage vI gradually increases from zero, and VI is less than VT, the comparator output is a positive saturation voltage, and VT is called the upper threshold (trigger) level. Window comparator: The circuit consists of two amplitude comparators and some diodes and resistors. When the potential level of the high-level signal is higher than a certain specified value VH, it is equivalent to the positive saturation output of the comparator circuit.

A co2 Laser Cutting Machine can reduce and engrave metallic substances, its performance is low. So, the CO2 Laser Machine is particularly for Cutting and Engraving non-metallic substances. Fiber Laser cutter, additionally referred to as metallic Laser Cutting Machine, is particularly for metallic substances.

CO2 Laser Cutting works with the aid of using focusing a high-depth infrared Laser beam thru a chain of mirrors and out thru a nozzle. It changed into the primary delivered greater than 50 years in the past and stays the conventional pillar for the industry. But despite the fact that it’s an older Cutting method, numerous capabilities of the CO2 Laser force its endured reputation for commercial welding and Cutting: it emits

CO2 Cutting is high-satisfactory for nice capabilities and acute angles, and usually makes use of axes and a portable desk to create the reduce.
