200G AOC is devided into QSFP28-DD AOC and QSFP56 AOC. The wavelength is 850nm and transmission distance of 1-100 meters.
QSFP56 AOC has 4 transmitting and receiving ports, transmission rate of each channel is up to 56Gbps, and the modulation method is PAM4.
QSFP28-DD has 8 transmitting and receiving ports, transmission rate of each channel is 28Gbps, and the modulation method is NRZ.
①200G AOC to 2*100G AOC
One port is connected with an 200G optical transceiver and the other one is connected with two 100G optical transceivers, which is mainly used in data center 200G to 2 100G Ethernet branch links. The maximum transmission rate is 212.5Gbps, power consumption of 200G is less than 4W and of 100G is less than 2.5W.
②200G AOC to 4x 50G AOC
Adopts 8-channel full-duplex active optical cable, one port is connected with an 200G optical transceiver and the other one is connected with four 50G transceivers, which is mainly used in data center 200G to 4 50G Ethernet branch links. The maximum rate is up to 206.25Gbps. The power consumption of 200G is less than 4W and of 50G is less than 1.5W.
The electrical signal is input through the A terminal, and the electrical signal is converted into an optical signal of a specific wavelength through the electrical-optical conversion device. The optical signal is modulated and coupled and then input into the transmission optical cable; after the optical signal reaches the B terminal, the photodetector will convert the optical signal After detection, the corresponding electrical signal is output after amplification, processing, and conversion.
