The 400G QSFP-DD ZR+ is a C-Band optical frequency tunable coherent optical module, that combines with best-in-class ultra-narrow line-width tunable lasers, high-speed modulators and high responsively coherent receivers. It provides 400GBASE-ZRPH throughput up to 120km over single-mode fiber (SMF) using a wavelength of 1528.58~1567.54nm via an LC/UPC connector. It can operate at temperatures between 0 and 75°C. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. It is intended to be used in conjunction with a host platform to support 400G transmission over optical links in DCI applications, meeting customers' high-speed data transmission needs over various distances.
