Abstract

Facilitated by variable differential-group-delay (DGD) modules, we propose a simple method to extend polarizationmode- dispersion (PMD) monitoring windows three times larger using either degree-of-polarization (DOP) for 40-Gbaud differential-phase-shifted-keying (DPSK) differential-quadrature-phase-shifted-keying (DQPSK) signals. Such approach can be further incorporated into PMD compensators.
