Abstract :
We describe an experimental evaluation of a Nyquist-WDM-based transmission system. Nine 10.7 GHz-spaced WDM channels were generated, carrying polarisation-division-multiplexed QPSK with digital Nyquist pulse shaping at 10 Gbaud. Back-to-back characterisation and long-haul transmission tests using a recirculating fibre loop are described, and a comparison of experimental performance with that predicted by theory, based on the Gaussian-noise model of nonlinear propagation, is carried out.
