Abstract

A compensation arrangement compensates for data signal changes from one of a group consisting of timing jitter dispersion and adaptive chromatic dispersion in an optical signal using a temporal imaging technique. An optical data input signal to the compensation arrangement includes a data pulse for each bit of data that have been subjected to a data signal change. In the compensation arrangement, a clock recovery arrangement generates 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 is responsive to the optical input data signal and the electrical clock output control signal from the clock recovery arrangement for generating an optical output signal. In this optical output signal, the phase of the data signal change associated with each data bit is delayed by a predetermined amount. A dispersive unit introduces a predetermined amount of dispersion to the data signal change components in the optical output signal from the phase modulator for generating an output optical signal from the compensation arrangement wherein the data signal change for each data bit is compensated for.
