            Abstract : 
We investigate the dependence of nonlinear penalty on symbol-rate in polarisation-multiplexed coherent DQPSK WDM-transmission systems over an uncompensated SSMF link with a fixed spectral efficiency of 2 bit/s/Hz. The performance is found to be similar, irrespective of the symbol-rate.
