AMG G63 4x4² „Nuthin but a G thang“.

The AMG G63 4x4² brings driving performance to the segment of unadulterated off-road vehicles in unexpected form.

The AMG 4.0-litre V8 biturbo engine generates 430KW (585HP) in this model, and delivers a maximum torque of 850Nm. This is available across a wide rev range between 2.500 and 3.500 rpm, and provides a sense of effortless superiority. It absolves a sprint from zero to 100 km/h in 5 seconds.

The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder „V“. Advantages: a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts. The eight-cylinder delivers its power with muscular torque in all engine speed ranges, combined with maximum efficiency for low fuel consumption and emission figures.

Two twin scroll turbochargers are used for optimal response.

The housing is divided into two parallel flow channels. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, that from the second and third cylinders to the other duct.

The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output, more torque at low revs and very fast response times.

I want to try red light therapy so badly!! Please share with us your experience when u try it and if u have any recs, I'd appreciate it a lot ❤️

I will give you an update in like 12 weeks time ( I have put it in my calender)

What I want to make crystal clear is that red light therapy should not be expensive. Its coloured light, albeit at a specific wavelength but coloured light nonetheless. When you look to buy red light products or any light therapy, you have to make sure you get the correct one wavelength. For red light, its 630nm to 700/850nm. The papers I have read seem to hinder between 700-850 so the one I got is closer to 630.

Like I said, there is no reason to be forking out hundreds to thousands of pounds for this. Literal chicken light works as well.

Closer Look at 400G QSFP-DD Optical Transceiver Module

Recent years have seen the evolution towards the 5G, Internet of Things  (IoT), and cloud computing, increasing pressure on data centers to ramp up both network capacity to 400G and driving providers to search for new solutions to achieve their 400G Data Center Interconnects (DCIs). 400G QSFP-DD optical transceiver module is becoming one of the most popular cutting-edge 400G DCI solutions. This article will provide a basic understanding of QSFP-DD optical transceiver modules.

What is the QSFP-DD Optical Transceiver Module?

Quad small form-factor pluggable-double density (QSFP-DD) is designed with eight lanes that operate at up to 25 Gbps via NRZ modulation or 50 Gbps via PAM4 modulation. It supports data rates of 200 Gbps or 400 Gbps and doubles the density. QSFP-DD is backward compatible with current 40G and 100G QSFPs. It is compliant with IEEE802.3bs and QSFP-DD MSA standards. QSFP-DD is available in single-mode (SM) and multi-mode (MM) fiber optic cables and includes digital diagnostics monitoring (DDM) to monitor parameters such as power, temperature, and voltage.

Types of 400G QSFP-DD Optical Transceiver Module

400G SR8 QSFP-DD 

400G SR8 QSFP-DD optical transceiver module is suitable for short-distance interconnection or multi-channel data communication. The transmission rate is up to 425Gbps, and the central wavelength is 850nm. The transmission distance is up to 70m or 100m through multi-mode OM3 and OM4 fiber.

400G DR4 QSFP-DD

400G DR4 QSFP-DD optical transceiver module achieves the transmission over single-mode fiber (SMF) with an MPO-12 connector. It supports a max transmission distance of 500m on SMF.

400G FR4 QSFP-DD

400G FR4 QSFP-DD optical transceiver module supports link lengths of up to 2km SMF with a duplex LC connector. It uses wavelength division multiplexing(CWDM ) technology, eight channels of 53Gbps PAM4 signals on the electrical side, and four channels of 106Gbps PAM4 signals on the optical side, which is twice the rate of the electrical side.

400G LR4 QSFP-DD

400G LR4 QSFP-DD optical transceiver module is designed with a built-in Gearbox chip that multiplexes the two channels' electrical input data into a single-channel outputs signal and then modulates it to the optical receiver end. The digital signal processor (DSP) basis gearbox converts eight channels of 25GBaud PAM4 signals into four channels of 50GBaud (PAM4) over an SMF cable with duplex LC connectors. It supports a transmission distance of up to 10km.

400G LR8 QSFP-DD

The 400GBASE-LR8 optical transceiver module supports link lengths of up to 10km over a standard pair of G.652 SMF with duplex LC connectors.

 400G ER8 QSFP-DD

The 400G ER8 QSFP-DD optical transceiver module supports link lengths of up to 40km over a standard pair of G.652 SMF with duplex LC connectors.

400G ER4 QSFP-DD

400G ER4 QSFP-DD optical transceiver module supports link lengths of up to 40km over a standard pair of G.652 SMF with duplex LC connectors. It has only four wavelengths for 4 LAN WDM channels 1295.56/1300.05/1304.58/1309.14nm.

Advantages of 400G QSFP-DD Optical Transceiver Module

Backward compatibility: Allowing the QSFP-DD to support existing QSFP modules (QSFP+, QSFP28, QSFP56, etc.). It provides flexibility for end-users and system designers.

 Adopting the 2x1 stacked integrated cage/connector to support the one-high cage connector and two-high stack cage connector system.

SMT connector and 1xN cage design: Enable thermal support of at least 12W per module. The higher thermal reduces the requirement for heat dissipation capabilities of transceivers, thus reducing some unnecessary costs.

ASIC design: Supporting multiple interface rates and fully backward compatible with QSFP+ and QSFP28 modules, thus reducing port and equipment deployment costs.

Applications

400G QSFP-DD optical transceiver module is used in 400G Ethernet, data centers, telecommunications networks, cloud networks, Infiniband interconnects, high-performance computing networks, 5G, 4K video, IoT, etc.

so Lucy remembered that as a teenager we really wanted to try near infrared photography, and we finally got some filters and stuff for it.

we're going to get a full spectrum converted camera eventually but in the meantime these were taken with an 850nm filter over our phone camera

and then this one where we played around more with the post-processing on it

we also have a few taken with a 590nm filter but we're figuring out what to do with those

OTDR

1. OTDR meaning

What OTDR meaning is that it is an instrument used for measuring fibre lengths and understand fibre loss. OTDR testing fiber inject high-powered light pulses into the fiber using specialized laser diodes. The parameters of optical fiber are measured by sending pulse signals and receiving the signal’s reflection. These reflections, known as Fresnel reflections, are measured by the OTDR to pinpoint the location of fiber condition within the fiber link.

2. Why OTDR testing fiber is important

After learn about OTDR meaning, let’s find out why OTDR testing fiber is important. The OTDR testing fiber is used to provide users with detailed information about the location of connectors, defects, and other kinds of element. It is a powerful tool that helps technicians and engineers assess the health of fiber optic cables.

It contributes to the assurance of network reliability and high performance. OTDR plays a critical role in testing, maintaining, and verifying the performance and quality of optical fiber connections. One of the advantage of using an ODTR testing fiber is the single-ended test—requiring only one operator and instrument to qualify the link or find a fault in a network completely.

3. Functions

The main function of an Optical Time Domain Reflectometer is to assess the insertion loss of a fiber link by analyzing the difference in backscatter between the near and far ends. Additionally, it measures the amount of light reflected from each event in relation to the launch pulse. This measurement is known as reflectance and is expressed in decibels as a negative value. Higher values, which are closer to 0 dB, indicate stronger reflections, which may suggest issues like poor connections.

4. Specifications of OTDR

OTDR specifications are important to understand so one can choose the right OTDR  testing fiber for a dedicated application.

Dynamic range  Dynamic range describes the measurement distance. The dynamic range determines the maximum observable length of a fiber. Dynamic range is one of its important parameters.

Wavelengths  An OTDR sends a pulse of light based on to the wavelength used for transmission when the fiber link is operational. The typical wavelengths are 850 nm and 1300 nm for multi-mode fiber and 1310 nm, 1550 nm and 1625 nm for single mode fiber. As our product Baudcom 6000 series OTDR can be used to test single-mode wavelengths of 1310nm, 1550nm, 1490nm, 1625nm and 1650nm, multi-mode wavelengths of 850nm and 1300nm as well as customized special wavelengths.
