Cisco QDD-400G-SR8-S= network transceiver module QSFP-DD

The Cisco QDD-400G-SR8-S Module (Figure 5) supports 400GE links and up to 8x 50GE breakouts or two 200GE breakout links lengths of up to 100m over OM4 MMF. The module has 8 pairs of MMF with an MPO-16 APC connector. It is compliant to the IEEE 802.3 400GBASE-SR4 and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over eight parallel pairs of fibers by 50Gbps signals per fiber. It can also be used as 8x 50GE breakout to SFP56-50G-SR modules or 2x QSFP-200G-SR4-S modules. FEC is performed on the host platform.
