Abstract:
1. A system comprising: a polarization beam splitter operable to split an input optical signal into a first polarization component and a second polarization component; a clock recoverer operable to recover a first clock from the first polarization component, recover a second clock from the second polarization component and determine a delay time between the first clock and the second clock; a tunable dispersion compensation module; a dispersion determiner operable to determine dispersion based on the delay time and operable to control the tunable dispersion compensation module to dynamically compensate for the dispersion determined by the dispersion determiner; and a polarization beam combiner operable to combine the first polarization component and the second polarization component to form a recombined signal; wherein the tunable dispersion compensation module is configured to act on any one of: a) the recombined signal; and b) the input optical signal, in order to dynamically compensate for the dispersion determined by the dispersion determiner.
