Abstract

Use of an optical single side-band (OSSB) modulation signal engenders high bandwidth efficiency because the OSSB signal occupies only half the channel bandwidth necessary for intensity modulation. Previous reports have been clarified that the binary phase shift keying OSSB (optical BPSK-SSB) signal has relative high sideband suppression ratio and tends to degrade the detected waveform as fiber input power increases. The waveform degradation is induced by self-phase modulation (SPM) in optical fiber. In order to equalize the waveform degradation, this paper proposes the novel pre-equalization scheme that makes additional phase modulation to optical BPSK-SSB signal. The depth of phase modulation is proportional to the optical power. The equalizing method was investigated in dispersion-compensated fiber transmissions with BPSK-SSB modulation. The results prove the equalization has the possibility of 15dB improvement of fiber input power compared to the no-equalization case.
