Abstract:
A high-order polarization mode dispersion (PMD) compensation arrangement for receiving an optical input data signal comprising first and second polarization components for each bit of data that have been subjected to PMD, the PMD compensation arrangement comprising:a clock recovery arrangement for generating an electrical clock output control signal including a predetermined phase modulation depth and phase and a data rate of the received optical input data signal;a phase modulator responsive to the optical input data signal received by the PMD compensation arrangement and the electrical clock output control signal from the clock recovery arrangement for generating an optical output signal wherein the phase of the first and second polarization components associated with each data bit are delayed by a predetermined amount; anda dispersive unit for introducing a predetermined amount of dispersion to the first and second polarization components in the optical output signal from the phase modulator for generating an output optical signal from the PMD compensation arrangement wherein the first and second polarization components for each data bit are in phase.
