Unrepeatered Transmission Reach Extension by Receiver-Side all-Optical Back-Propagation

Improvements in SNR (1.98 dB), Mutual Information (0.95 bit/symbol) and maximum transmission distance (almost 12%) are demonstrated for dual-polarization WDM 16-QAM unrepeatered transmission using optical-phase-conjugation-based back-propagation at the receiver through power and dispersion engineering.
