QSFP Cable and Connectors Assemblies

A quad (4-channel) Small Form-factor Pluggable Optics Transceiver is also known as a QSFP cable. For applications requiring 40 Gigabit Ethernet (40GbE) data transfers, it is a small, hot-pluggable fiber optical transceiver. They are often used for the implementation of 40G Ethernet, Infiniband, and other communications protocols in data centers.

It connects a fiber optic or copper cable to network equipment, such as a switch, router, media converter, or similar device.

In addition to copper cable media, QSFP+ optic transceivers are made to support Serial Attached SCSI, 40G Ethernet, 20G/40G Infiniband, and other fiber optic communication standards. In comparison to SFP+ optic modules, the QSFP28 cable significantly increases port density by 4x.

Optical transceivers are compact, strong devices that add fiber ports to switches or other networking equipment by connecting them to copper or fiber optic cables. Data is transmitted using optical fiber in conjunction with fiber optics in the form of light pulses that travel at very high speeds and can cover very long distances. The transceiver, which is a laser with a certain wavelength that transforms electrical signals into optical signals, is a crucial part of the fiber optic network. The data is then converted into a signal with a specific wavelength by the transceiver and sent over the optical fiber. Wideband signals are those that are 850 nm, 1310 nm, and 1550 nm in wavelength. Narrow bands are the term for CWDM or DWDM signals. Each channel is unable to interact with the others due to the special property of light.

This indicates that a network can handle the transmission of both wideband and narrowband signals. Direct attach copper (DAC), active optical cables (AOC), optical modules, and active copper cables are all types of QSFP interconnects (ACC). The least costly choice is DACs. They offer a connection that depends on host signal processing. The maximum length that can be achieved depends on the cable assembly's insertion loss, which is determined by its length and cable gauge and is guided by the IEEE specifications (see below) (AWG). The AWG of a wire has an inverse relationship with its size. AWG and wire diameter for QSFP cable assemblies are plotted in the table below.

My PC Screen Upgrades Review - Part 2 (w/ my paper dolls) [Recorded on Jan 14th, 2024]

Hello, February! The wait is over! 😁 Because here's "Part 2" of my "PC Screen Upgrades Review" (featuring my paper dolls). Yup, this is my second attempt after I replaced the CPU cooling and added two PC fans in June of 2023. 🖥️🔧 This year is for the screen monitor by replacing/installing this trio of PC-related items! 😁

But before that, if you haven't seen my previous topics that related to my "PC Upgrades", then I'll provide some links down below: ↓ 😉

And don't forget this "Part 1", in case you missed it → [CLICK ME!].

So, without further ado, let's get started:

My Recorded Video [edited by: Filmora 9] 🎦🎞️: ↑

• Once again, in my recorded video, I'm showing off one-by-one of my trio of PC upgrades before I installed. 🖥️🔧🙂 Please, enjoy my unboxing video. Otherwise, you could at least check it out my snapshots, down below. ↓ 😉

14th to 24th Image(s) 📷📲: ↑

• Okay, unboxing time - snapshot edition! 😊 First off is the CERVVO GPU Card. This box contains a Product Specifications booklet with few instructions, and the main item covered in anti-static plastic to prevent conducting electricity. I also mentioned, that the GPU Card also available in black color, but the seller gave me a white variant. After all, it matches the color from the old MSi GTX 750 Ti GPU.

25th to 29th Image(s) 📷📲: ↑

• Speaking of, here's a comparison with my aforementioned one, and in terms of length & size sees through our visions. 👀

30th to 33rd Image(s) 📷📲: ↑

• Okay, let's moved on to my next item, this is the Ad-Link HDMI to VGA converter. And I confirmed, that the AOC's old VGA port would fit in right through the converter. Plus, a 3.5mm audio jack port built right in, with the included auxiliary cable. Although, I don't need it, to be honest. 🤷‍♀️

34th to 42nd Image(s) 📷📲: ↑

• And finally, the Fuzion PC power supply. With no additional accessories, this thing will slapped on any format desktop tower case. And unlike my old PC power supply, aside from the aforementioned PCI-E ports, the 24-pin ATX power connector cable was covered in nylon braided-ish material. Yes, I said "Nylon-Braided" because it looks like one, although the material doesn't have the same as the soft thread nylon-braided ones from our existing USB cables for mobile devices. 🙂

43rd Image 📷📲 [Jan 12th, 2024]: ↑

• Ah yeah, I forgot. Here's the specs information about the old PC Power Supply from Powerlogic as a comparison against my new PC Power Supply from Fuzion. ⚡🖥️ To be honest and in my opinion, I wish my new Fuzion PC PS (Power Supply) would have the same specs as my old Powerlogic PC PS. Just saying. ☺

Well, that's the end of my "Part 2". "Part 3" is now available! Pls proceed → [CLICK ME!]. 🙂

And GOOD NEWS! I'm attending my job as a "Volunteering Worker" for the "Person's With Disabilities and Senior Citizen's Cash For Work Program"! 😁👷‍♂️ "Four hours" on weekdays for "Four months" until I get paid! So, I'll do my best! 😊

Well, that's all for now.

Data Center Cabling Solution: Active Optical Cable

As data rates rise and data center grows in size, copper cable is getting stretched to its limits. However,  active optical cable (AOC) has emerged to replace copper cable in data centers and high-performance computing (HPC) applications. It provides high-speed, high reliability, high flexibility, and low power consumption. This article will provide some knowledge of AOC cable. 

What is an Active Optical Cable?

Active optical cable (AOC) is an optical fiber jumper cable terminated with optical transceivers on both ends. It uses electrical-to-optical conversion on the cable ends to improve the speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.

Active Optical Cable Structure

AOC cable consists of the fiber optic connector and fiber cable. The connection between fiber cable and fiber optic connectors is not separable. If the fiber optic connector or fiber cable needs to be changed, they should be removed together. The electrical and optical signal conversion can be achieved right through each end of the optical fiber.

Active Optical Cable Types

There are several varieties of AOC cable available on the market , including 10G SFP+ AOC, 25G SFP28 AOC,40G QSFP+ AOC, 56G QSFP+ AOC, 40G QSFP+ to 4x SFP+ breakout AOC, 40G QSFP+ to 8x LC breakout AOC, 100G QSFP28 AOC, 100G QSFP28 to 4x SFP28 breakout AOC and 120G CXP AOC, etc. These AOC cables are commonly used for short-range multi-lane data communication and interconnect applications between two devices, such as rack-to-rack, shelf-to-shelf interconnect, storage, hubs, switches, routers, servers, etc.

Features and Benefits

AOC cable provides low power consumption, high density, high speed, high reliability, high security, small size, strong heat dissipation, low electromagnetic interference, long transmission distance, low energy consumption, low latency, lightweight, and ease of installation.

Application Scenarios

AOC Cable is used to connect top-of-row (ToR) switches to end-of-row aggregation switches, and to connect the ToR switch with storage subsystems at reaches greater than direct attach copper (DAC) limits of 3-7 meters. The following three scenarios show the specific applications.

Scenario 1:  AOC cable is used to connect two switches directly.

Scenario 2: The breakout AOC cable provides a highly cost-effective way to connect within racks and across adjacent racks. The following figure shows 40GbE QSFP+ to 4 x SFP+ AOC cable connecting to a 40G QSFP+ port switch on one end, and to four 10G SFP+ port switches on the other end.

Scenario 3: For the long-haul transmission between the two switches, a suitable solution is recommended to use single-mode patch cable, OEO converters, and AOC cables, which can provide seamless integration of different fiber types by converting multi-mode fiber to single-mode fiber.

Conclusion

AOC cable achieves high data rates over long reaches interconnection, which is the best solution for data centers and high-performance computing applications.
