XPM penalty mitigation for a 42.7-Gb/s DQPSK channel co-propagating with 10.7-Gb/s OOK channels using SSMF and dispersion map

We demonstrate that the XPM penalty on a 42.7-Gb/s DQPSK channel from co-propagating 10.7-Gb/s OOK channels is reduced to less than 3 dB at practical power levels using SSMF and large residual dispersion per span.
