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. This transceiver is also the one capable of reaching the longest transmission distance thanks to the high-performing O-FEC algorithm. With compliance to OIF MSA standards and multi-vendor interoperability, the module allows interoperability and rapid deployment with other standard-compliant components. It is intended to be used in access, edge, core, and data center, supporting an open and interoperable networking ecosystem.
