Cisco QDD-2X400G-FR4= network transceiver module Fiber optic 400000 Mbit/s QSFP-DD

The Cisco QDD-2X400G-FR4 module supports link lengths of up to 2 km SMF with two duplex LC connectors. It is compliant to IEEE 802.3cu for 400GBASE-FR4 requirements and 100G Lambda MSA group. The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device. FEC is performed on the host platform.
