Cisco QDD-400G-FR4-S Compatible 400GBASE-FR4 QSFP-DD PAM4 1310nm 2km DDM/DOM Duplex LC SMF Optical Transceiver Module 100G EDR It supports scalable spine–leaf and

It supports scalable spine–leaf and rack-to-rack architectures

As server network interface card (NIC) speeds continue to increase

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

and it is also compatible with the NDR IB network protocol

SN4600 allows for maximum flexibility

Cisco QDD-400G-FR4-S Compatible 400GBASE-FR4 QSFP-DD PAM4 1310nm 2km DDM/DOM Duplex LC SMF Optical Transceiver Module 100G EDR It supports scalable spine–leaf andDescription 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
