title: Transmission of 100 Gb/s coherent PDM-QPSK over 16 x 100 km of standard fiber with allerbium amplifiers.
abstract: We report on the performance of 100 Gb/s coherent non return-to- zero (NRZ-) polarization division multiplexed (PDM-) quadrature phase shift keying (QPSK) transmission over 16 x 100 km of standard single mode fibre under constraints of typical transparent terrestrial networks, employing Erbium-Doped Fibre Amplifiers. We first evaluate the impact of cross non linear effects onto the performance of 100 Gb/s coherent PDM-QPSK signals and we investigate the impact of shifting one of the polarization multiplexed tributaries by half a symbol duration with respect to the other one. Finally we show that this solution is robust against channel-to-channel cross-talk from transparent nodes and does not suffer from performance degradation stemming from co-propagating 40 Gb/s channels.
