16x112Gb/s NRZ-DQPSK WDM transmission over 604 km SSMF including high PMD fibres
05 July 2010
A 16x112 Gb/s field trial with EDFA only was performed over legacy fiber infrastructure partially with high PMD. Based on 43 Gb/s components we demonstrate by use of 112 Gb/s NRZ-DQPSK modulation format Metro DWDM transmission with carrier-grade margins of more than 4 dB over ultimate Metro distances.
