The Cisco QDD-8X100G-FR module supports 100G breakout link lengths of up to 2 km. The module has eight pairs of single-mode fiber with MPO-12 APC connectors. It is compliant to the IEEE 802.3cu for 100GBASE- FR1. The 400 Gigabit Ethernet signal is carried over eight parallel lanes by one wavelength per lane. It can be used as 8x100G breakout to QSFP28 100G-DR (up to 500 m), 100G-FR (up to 2 km), and 100G-LR (up to 2 km). It may also be used as two independent 400GBASE-DR4 transceivers in a single port. FEC is performed on the host platform.
