Novel method for measuring nonlinear coefficient in optical fibers based on phase mismatching four-wave-mixing is proposed. With simple setup, we demonstrate measurements for both high nonlinearity dispersion-shifted fiber and low nonlinearity standard SMF.
The authors demonstrate the successful transmission of 10 channels with 224-Gb/s POLMUX-16QAM modulation (28 GBaud) on a 37.5-GHz wavelength grid. Using large- pure-silica-core fibers they show a 656-km transmission distance with a spectral efficiency of 5.6 b/s/Hz. They report a back-to-back performance penalty of 3.5 dB compared to theoretical limits at the forward-error correction...
We compare the transmission performance of 112-Gb/s POLMUX-QPSK modulation over large-Aeff Pure-Silica core fiber and SSMF using EDFA-only amplification. The higher nonlinear threshold of the large-Aeff fiber allows for a 40% improvement in transmission distance.
