We propose a C+ L-band lumped repeater configuration using optical phase conjugators
(OPCs) and erbium-doped fiber amplifiers (EDFAs). The OPC based on a highly efficient …

The weakness of the dispersion-managed link, which is combined with optical phase
conjugation to compensate for optical signal distortion caused by chromatic dispersion and …

All-optical wavelength converters (AOWCs) based on state-of-the-art highly nonlinear optical
fibers (HNLFs) are best matched with future large-capacity optical networks because of their …
