The 400G QSFP-DD ZR+ Pro 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 modulattion format.The transceiver is compliant with the OIF QSFP-DD MSA and supports digital diagnostics functions.It is intended to be used in conjunction with a host platform to support 400G transmission over optical links in DCI applications.
