How to choose Active Fiber Optic Cable AOC?

How to choose Active Fiber Optic Cable AOC?

Active Optical Cable, AOC is short for active optical cable, which is composed of multi-mode fiber, optical transceiver, control chip and parallel optical module. Optical transceivers at both ends provide photoelectric conversion and optical transmission capabilities to increase the cable's transmission speed and distance without compromising compatibility with standard electrical interfaces. It is mainly used for short distance multi - channel data communication applications.

What is AOC Active Fiber Optic Cable? What are the categories?

What is AOC Active Fiber Optic Cable? What are the categories?

AOC Active Cable is a highly efficient integrated cable component designed for short-range multi-channel data communication and interconnection applications, ranging from 1 to 100 m. It is suitable for supercomputers and SDR, DDR and QDR based on InfiniBand. In addition, AOC active optical cable has many advantages compared with connected copper cable, such as lower transmission power on the system link, only a quarter of the weight of directly connected copper cable, slightly half the volume of copper cable, and has better air flow heat dissipation in the wiring system of the computer room, the bending radius of the optical cable is smaller than that of copper cable, and the transmission distance is longer. The bit error rate of product transmission performance is also better.
