40-Gb/s 2-Channel all-optical 3R regeneration using data-pumped fiber parametric amplification based on HNLF

Abstract

40-Gb/s 2-Channel all-optical 3R regeneration with simultaneous wavelength conversion has been realised by a fiber parametric amplifier(FPA) with the data signal to be regenerated as the pump,eliminating the unequal suppression of noise between bit0 and bit1. Signal to noise ratio is improved respectively from 2.7,2.4 to4.9,5.2.
