Signal noise suppressed and accumulated in all-optical regeneration based on saturation of FWM in a highly nonlinear fiber is investigated. Two modulation formats, on-off keying (OOK) and differential phase-shift keying (DPSK), were use in this study. input signal OSNR was 20 dB/0.1nm. mark and space level noise were evaluated by measuring signal threshold value. The regenerator suppressed mark level noise of both OOK and DPSK signals. however, noise at space level was amplified, which degraded OOK signal performance.
