160 Gbit/s-based field transmission experiments with single-polarization RZ-DPSK signals and simple PMD compensator

Single-polarization 160 Gbit/s-based field transmission experiments have been successfully conducted. By utilizing 160 Gbit/s RZ-DPSK signals and a simple PMD compensator, single-channel transmission and 8 WDM transmission with 300 GHz channel spacing have been achieved over the inter-city 200 km SMF.
