An experiment of all-optical regeneration of short-pulse differential phase-shift keying (DPSK) signals using fiber nonlinearity is reported. Bit error rate (BER) performance is measured for a two-span transmission system where the regenerator is inserted between the spans. Two cases are examined where the signal degradation before the regenerator is due mainly to nonlinearity of the transmission fiber, i.e., the nonlinear phase noise, and is due to addition of amplified spontaneous emission (ASE). The regenerator is shown to be more effective in recovering signal quality in the former case of degradation due to phase noise.
