Abstract
Compensating for intercarrier nonlinear distortion allows launching higher
power into the transmission fiber and it leads to an increase in the
transmission distance. Numerical calculations show that the launch power is
increased by 10 dB and the maximum transmission distance is more than
tripled, when the optical repeater spacing of 80 km, dispersion-shifted
fiber, and signal format of 10 Gb/s nonreturn-to-zero are assumed. It is
experimentally demonstrated that waveform distortion due to the four-wave
mixing (FWM) among different carriers in wavelength-division multiplexing
(WDM) becomes deterministic by phase-locking optical carriers and that FWM
distortion can be compensated at 5 Gb/s with three-channel condition by
employing DSP at the transmitter or receiver.
