Switch SFP Part QSFP-DD-400G-DR4-C is in UK stock and 100% Compatible with Cisco part QSFP-DD-400G-DR4. The 400 Gigabit Ethernet signals are transmitted over four parallel channels on one wavelength per channel and supports Single mode fiber (SMF) link lengths of up to 500m via MPO-12 connectors. 

This module supports eight electrical interface channels that operate in 100G PAM4 coding mode to produce 400G (4x100G) data rates. It is compliant with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard.

The multiplexing and demultiplexing of eight wavelengths are managed within the device and connect 400G signals from the server side (NIC) to the data center aggregation switch.
