Cisco QDD-400G-SR4.2-BD Compatible 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.
