We describe the impact of fiber nonlinear effects in coherent optical communication systems and discuss some nonlinearity compensation techniques.

We investigated the mitigation of distortion due to SPM and dispersion in 40 Gbit/s NRZ WDM transmission using a multichannel optical equalizer.

We receive the full optical field of a 176-GHz wide, 1.2-Tb/s PDM-16QAM superchannel after 960-km TWRS using a spectrally-sliced coherent receiver.

We demonstrate compensation of fiber nonlinearities using repeated optical phase conjugation (OPC) in a WDM system with 8 32-Gsym/s PDM 16-QAM channels, showing improved performance over a single m

We demonstrate compensation of fiber nonlinearities using optical phase conjugation of an 8-channel WDM 32-Gbaud PDM QPSK signal.

We discuss various electronic and optical techniques to reduce the impact of fiber nonlinearity and improve other system performance aspects in the context of optically-routed networks.

After reviewing models and mitigation strategies for interchannel nonlinearity, the synergic effect of symbol-rate optimization and phase-noise compensation is investigated.

We demonstrate fiber nonlinearity mitigation by using multiple optical phase conjugations (OPCs) in the WDM transmission systems of both 8 × 32-Gbaud PDM-QPSK channels and 8 × 32-Gbaud PDM-16-QAM c

We experimentally demonstrate fiber nonlinearity mitigation using multiple optical phase conjugations (OPCs) in WDM transmission systems with 8 × 32-Gbaud PDM-QPSK channels and with 8 × 32-Gbaud PD

Electroabsorption modulators (EAM) have proved to be very attractive both as optical sources (monolithically integrated NRZ transmitters and RZ pulse generators) as well as for very fast signal pro
