3.6-Tbps Duobinary 16-QAM Transmission with Improved Tolerance to Cascaded ROADM Filtering Penalty
23 September 2018
We successfully transmit 9-channel duobinary 16-QAM at bitrate of 3.6 Tb/s over 2100 km fiber in a system impaired by cascaded ROADM filtering. Duobinary shaping leads to significant reach extension with improved tolerance to bandwidth narrowing effect.
