AOC is short for Active Optical Cable, which consists of multimode fiber, optical transceiver, control chip and parallel optical module. The optical transceivers at both ends provide photoelectric conversion and optical transmission functions to improve the transmission speed and transmission distance of the optical cable without compromising compatibility with standard electrical interfaces. It is mainly used in short-range multi-channel data communication applications.
Why use Active Optical Cable (AOC)?
AOC is used primarily because of its assemblies to replace copper technology in data center and high performance computing (HPC) applications.
As far as we know, the weight and volume of passive optical cable are large, which do not meet the high density requirements of data centers, and due to the nature of electrical signals, electromagnetic interference (EMI) limits the performance and reliability of copper. However, AOC break through the limitations of passive optical cables and play an important role in high-speed data transmission.
What are the advantages of AOC?
What factors should be considered when choosing a cost-effective active optical cable (AOC)? This is a concern of many people. I hope the following analysis can help you.If you have better suggestions, please contact us to discuss.
AOC connection port
When selecting AOC, it is necessary to determine whether the optical port of the equipment is SFP+ or QSFP+.
Data type and rate of transmission
AOC suitable for Ethernet switches, LAN:1G 10G 40G Ethernet；
Storage service,SAN:1G 2G 4G 8G Fiber Channel；
Infini Band switch, Infini Band:SDR DDR QDR(2G 5G 10G)。
Transmission distance
For Ethernet services, 10G SFP+ AOC, 40G QSFP+ AOC cable: OM2 cable, transmission distance is 20m; OM3 cable can reach 300m.
For storage services, 10G SFP+ AOC: With OM3 fiber optic cable, 4G service transmission distance can reach 380m, and 8G service transmission distance can reach 150m.
Quality guarantee
Common AOC include H3C, Cisco, etc. The price of the original factory is prohibitively high. At the same time, the market is mixed, there are many old goods and even fakes. It is especially important to choose a brand-compatible manufacturer.
