Abstract
We present experimental and numerical investigations of Kerr
nonlinearity compensation in a 400-km standard single-mode fiber link with
distributed Raman amplification with backward pumping. A dual-pump
polarization-independent fiber-based optical parametric amplifier is used for
mid-link spectral inversion of 5 × 28-GBd polarization-multiplexed 16-
QAM signals. Signal quality factor (Q-factor) improvements of 1.1 dB and
0.8 dB were obtained in the cases of a single-channel and a five-channel
wavelength-division multiplexing (WDM) system, respectively. The
experimental results are compared to numerical simulations with good
agreement. It is also shown with simulations that a maximum transmission
reach of 2400 km enabled by the optical phase conjugator is possible for the
WDM signal
