Claim of US Patent No. 9,374,188

1. A transmitter for use in a wavelength division multiplexed system having at least two channels that are carried over a
single fiber, said at least two channels each, respectively, employing two polarizations, said transmitter being adapted to
offset a start time of a symbol of data that is carried by a first of said polarizations of a first of said at least two channels
with respect to a starting-next-in-time symbol of data carried by a second of said polarizations employed by said first of
said channels by less than a symbol period.
