| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | 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 carrier-suppressed OSSB (OSSB-SC) 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 in optical fiber. In order to equalize the waveform degradation, this paper proposes the novel equalization scheme that makes additional phase modulation to OSSB-SC signal. The depth of phase modulation is proportional to the optical power. Post and pre equalizing method was investigated and the results prove the equalization has the possibility of 15dB improvement of fiber input power. | |
