Abstract :
We implement 126-GHz bandwidth coherent receiver and demonstrate multi-channel 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.
