AOC is stands for Active Optical Cable, which consists of multimode fibers, optical transceiver devices, control chips, and parallel optical modules. The optical transceivers at both ends provide photoelectric conversion and optical transmission functions to improve the transmission speed and distance of the optical cable, without weakening compatibility with standard electrical interfaces. Mainly used for short distance multi-channel data communication applications.
Why use active fiber optic cable AOC?
The main reason for using active fiber optic cables is to replace copper technology in data centers and high-performance computing (HPC) applications with active fiber optic cable components. Due to the large weight and volume of passive copper cable DACs, they 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, the emergence of active optical cable (AOC) has broken through the limitations of passive optical cables and played an important role in high-speed data transmission.
What are the advantages of active fiber optic cable AOC?
What factors should be considered when choosing a cost-effective active optical cable (AOC)?
When selecting AOC connection ports, it is necessary to first determine whether the optical port of the device is SFP+ or QSFP+.
The type and rate of data transmitted
1, AOC optical cable is suitable for Ethernet switch machines, LAN: 1G 10G 40G Ethernet;
2, Storage services, SAN: 1G 2G 4G 8G Fiber Channel;
3, InfiniBand switch, InfiniBand: SDR DDR QDR (2G 5G 10G)
Transmission distance
For Ethernet services, 10G SFP+ AOC, 40G QSFP+ AOC cables: OM2 optical cable with a transmission distance of within 20m; The optical cable of OM3 can reach 300m. For storage services, 10G SFP+AOC: using OM3 optical cables, the transmission distance of 4G services can reach 380m, and the transmission distance of 8G services can reach 150m.
