摘要：

We investigate the potential of 100Gb/s polarization division multiplexed (PDM-) quadrature phase shift keying (QPSK) paired with coherent detection to enable the future capacity upgrade of current networks designed for 10Gb/s non-return to zero (NRZ) on-off keying data. We experimentally assess the tolerance to nonlinear effects of such a solution over optical systems based on low chromatic dispersion fibres. We particularly study the performance penalties brought by co-propagating channels (either PDM-QPSK or 10Gb/s NRZ) onto 100Gb/s PDM-QPSK data, in which both polarisation tributaries are over-modulated with return-to-zero and temporally interleaved by half a symbol period. Besides, we investigate one option to overcome these limitations: introducing band-gaps in the multiplex.
