400 Gbps PM-QPSK Transmission for Metro-DCI Applications Employing 20 Gbaud Transmitter

Not Accessible

Your library or personal account may give you access

Abstract

A PM-QPSK superchannel transmission is experimentally demonstrated for 400-Gbps data center interconnects, based on 20-GBd transmitter and coherent receiver technology, yielding a spectral efficiency of 4-b/s/Hz.
