Comelink QSFP-DD-400G-SR4.2 400Gb/s QSFP-DD SR4 BiDi PAM4 850nm/910nm 100m/150m OM4/OM5 MMF MPO-12 FEC Optical Transceiver Module
400G QSFP-DD SR4 BIDI PAM4 Optical Transceiver Module (850nm/910nm MPO-12 OM4/OM5 100m/150m with FEC DDM)
400Gb/s QSFP-DD SR4 BiDi Module, which is capable of supporting Ethernet links of up to 400 Gigabits and up to four 100 Gigabit Ethernet breakout link lengths over OM4 Multimode Fiber (MMF) at distances of up to 100 meters. The module includes four pairs of MMF featuring an MPO-12 UPC connector and complies with the IEEE 802.3bm protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standards. To transmit the 400 Gigabit Ethernet signal, the module employs two bidirectional wavelengths per fiber across four parallel pairs of threads. Additionally, the module can function as a 4x100GE breakout to QSFP-100G-SR1.2 modules, and Forward Error Correction (FEC) is conducted on the host platform.
