The Cisco QDD-400G-SR4.2-BD module supports 400GE links and up to four 100GE breakout link lengths of up to 100m over OM4 MMF. The module has four pairs of MMF with an MPO-12 UPC connector. It is compliant to the IEEE 802.3bm protocol and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over four parallel pairs of fibers by two 50Gbps bidirectional wavelength per fiber. It can also be used as 4x100GE breakout to QSFP-100G-SR1.2 modules. FEC is performed on the host platform.
