The 400G QSFP-DD ZR+ Transceiver is a high performance, high output power,cost effective module for optical datacommunication applications from 100G to 400G.The 400G QSFP-DD ZR+ is designed to 100G/200G long haul and 300G/400G Metro IP over DWDM applications without inline chromatic dispersion compensation.
The 400G QSFP-DD ZR+ is a C-Band optical frequency tunable coherent optical module, combines 7nm coherent DSP ASIC functionality with best in class ultra-narrow line-width tunable lasers, high speed modulators and high responsively coherent receivers to deliver high performance at 100G DP-QPSK/ 200G DP-QPSK / 300G DP-8QAM / 400G DP-16QAM modulation format. With EDFA and VOA inside the TX optical path the output optical power is -10~1dBm tunable, at the 400G Gray Light mode (193.7THz) the output power is 4dBm.
The 400G QSFP-DD ZR+ coherent transceiver is compliant with the OIF QSFP-DD MSA. Digital diagnostics functions are available via an I2C interface as specified by the QSFP-DD MSA. Mechanical dimensions, connectors and footprint conform to QSFP-DD MSA. The module is 18.35 mm x 93.26 mm x 8.50 mm in size and hot pluggable by 76 PIN PAD and host connector.
