Titel
Coherent reception and 126 GHz bandwidth digital signal processing of CO-OFDM superchannel generated by fiber frequency conversion
Abstract
We implement 126-GHz bandwidth coherent receiver and demonstrate multichannel reception with nonlinear compensation (NLC) of a precisely frequency-allocated four-channel 28-GBd-QPSK OFDM superchannel sequentially aggregated using fiber-optic signal processing. Multi-channel back propagation-based NLC improved transmission performance.
