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.

Why use active Fiber Optic AOCs?

Active fiber optic cables are used primarily to replace copper technology in data center and high performance computing (HPC) applications.

Due to the heavy weight and volume of passive copper cable Dacs, they do not meet the high density requirements of data centers, and electromagnetic interference (EMI) limits the performance and reliability of copper due to the nature of electrical signals. However, the emergence of active fiber optic cable AOC breaks through the limitations of passive fiber optic cable and plays an important role in high-speed data transmission.

What are the advantages of active Fiber Optic Cable AOCs?

What factors should be taken into consideration when choosing a cost-effective active optical cable (AOC)?

C-FLINK's analysis is as follows:

AOC connection port

Choose AOC to determine the device's optical port is SFP+ or QSFP+.

Data type and rate of transmission

AOC cable is suitable for Ethernet switching machine, LAN:1G 10G 40G Ethernet;

Storage service, SAN:1G, 2G, 4G, 8G Fiber Channel;

InfiniBand switch. InfiniBand:SDR DDR QDR(2G 5G 10G).

Transmission distance

For Ethernet services, 10 Gbit/s SFP+ AOC and 40 Gbit/s QSFP+ AOC cables are OM2 cables. The transmission distance is within 20m. The OM3 cable can reach 300m.

For storage service, 10G SFP+ AOC: with OM3 cable, 4G service transmission distance can reach 380m, 8G service transmission distance can reach 150m.

Quality assurance

Common AOCs include H3C, Cisco, etc., but due to the high price, the procurement cost is high. At the same time, the market is mixed, there are a lot of old goods and even fake goods, choose a brand compatible strength manufacturers is particularly important. C-FLINK specializes in the development and production of communication cables, compatible with switches and routers of various brands.
