Demo: 400 Gbps Transmission over 800km in a 75 GHz-spaced DWDM System

NeoPhotonics says it has demonstrated that its 400ZR+ QSFP-DD coherent pluggable transceiver can effectively transmit at a 400 Gbps data rate over a distance of 800 km in a 75 GHz-spaced DWDM system with more than 3.5 dB of OSNR margin in the optical signal. This 400ZR+ coherent pluggable transceiver module is based on NeoPhotonics high ...
