Abstract
We report experimental results on the transmission performance of a
coherent dual-polarization quadrature phase-shift-keyed (DP-QPSK) transceiver
with real-time electronic equalization over fiber having 50-ps mean polarization
mode dispersion (PMD). Both single-channel, single-span and multi-channel,
multi-span measurements were performed over the high PMD fiber, which has
near Maxwellian statistics for the differential group delay (DGD) as well
as higher order PMD as expected for a long, mode-coupled fiber. Transmission
of eighty channels was achieved over 8$\,
\times \,$100 km of TrueWave Reduced Slope fiber plus distributed
high PMD fiber, where individual channels had instantaneous DGD as high as
127 ps. The dependence of the OSNR penalty on the launch state of polarization
was evaluated and found to be minimal, and the contribution of fiber nonlinearities
to the transmission penalty was evaluated for two different per-channel launch
powers. Finally, using a transceiver equipped with forward-error-correction,
error-free transmission over the 800-km link was demonstrated over a 10-day
period; during this time the DGD of the measured channel varied from 13 to
116 ps.
