This module offers a cost-effective 100Gbps solution for data centers utilizing parallel fiber infrastructure rather than wavelength division multiplexing

Cisco QDD-400G-FR4-S Compatible 400GBASE-FR4 QSFP-DD PAM4 1310nm 2km DDM/DOM Duplex LC SMF Optical Transceiver Module Model:QDD-400G-FR4 For modern AI cloudsDescription NADDOD Cisco QDD 400G FR4 S Compatible QDD 400G FR4 optical transceiver features a duplex LC connector and supports transmission distances of up to 2 km over parallel single mode fiber. It converts eight 50 Gb s PAM4 electrical signals into four CWDM optical channels, multiplexed into a single 400 Gb s optical link. On the receiving side, the 400 Gb s optical signal is demultiplexed into four CWDM channels and converted back into eight 50
