Description

ZK-Q56-2H31L-S4 Optical Transceiver is a QSFP56 transceiver module designed for 400m optical communication applications with single mode fiber. It is compliant with IEEE 802.3-2018 200GBASE FR4, SFF-8679, and CEI-56G-VSR-PAM4 standards. Digital diagnostic management interface (DDMI) is realized by I2C interface in compliance with CMIS4. The module is RoHS 2 compliant.

The module can convert 4-channel 53.125 Gbps electrical data to 4-channel optical signals, and multiplex them into a single channel for 212.5 Gbps optical transmission. Similarly, it optica lly de- multiplexes a 212.5 Gbps input into 4-channel signals, and converts them to 4-channel output electrical data on the receiver side. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interf erence. A block diagram is shown in below picture.
