Abstract :
The optical transmission system is being upgraded from 10G to 40G even 100G due to the increasing demands of wide-bandwidth network. We numerically investigate the nonlinear tolerance of 112 Gb/s polarization-multiplexed return-to-zero differential quadrature phase-shift keying signal with different types of neighboring channels on a 50-GHz grid over 1,000 km field fiber. Our transmission result proves showing the feasibility of 100G overlaying existing 10G/40G commercial systems despite the presence of strong cross-phase modulation.
