What is an Active Optical Cable (AOC Cable)?

AOC cable market recognition has continued to grow on its demand with the increase on bandwidth usage.

(AOC) can be defined as a short-range multi-channel data communication and interconnection applications which isoften based on multi-mode fibers while some (like PSM4) is on single-mode fiber. A key attribute is that AOC employs the same connectors as pluggable optics and performs electrical-to-optical conversions at each cable end. In practice, this means QSFP terminations for 40GE and 100GE and SFP terminations for 10GE and 25GE. An AOC is often based on multi-mode fibers while some (like PSM4) is on single-mode fiber.

                   Why use an active optical cable (AOC cable)?

The transmission of optical communication should normally belong to the passive part, but AOC is an exception. AOC consists of multimode fiber, fiber transceiver, control chip and module. It uses electro-optic conversion on the cable end to improve the speed and distance performance of the cable without sacrificing compatibility with the standard electrical interface. With people wanting to provide more information at their fingertips, our communications systems will need to be faster, and AOC is one of the best solutions to this problem. Compared with the direct connection copper cable used for data transmission, AOC has the advantages of light weight, high performance, low power consumption, low interconnection loss, strong EMI anti-jamming and high flexibility. At present, AOC has been widely used in many fields and has promoted the entry of traditional data centers into optical interconnection.Mainly the invention of active optical cable (AOC) components to replace copper technology in data centers and high-performance computing (HPC) applications. We know that copper passive dual-axis cables are heavy and bulky, making it difficult to physically manage the data center. Due to the nature of electrical signals, electromagnetic interference (EMI) limits the performance and reliability of copper. Although the copper cable had so many drawbacks, it was mainstream at the time, and the idea of the AOC cable almost seemed too good to be true. However, the advantages of AOC cable make the predecessors appear old and uncomplicated, change the limitation of copper passive dual-axis cable, and play an important role in high-speed data transmission. Today, a variety of active optical cables have been introduced on the market, such as 10g SFP + AOC, 40g QSFP + to QSFP + AOC, 40g QSFP + to 4 SFP + breakout AOC and 40g QSFP + to 8XLC Breakout AOC.
