ABSTRACT:
A method of reducing correlation between channels in an optical communication network. A transmission characteristic of first data on a first channel is altered to reduce correlation between the first data and second data on a second channel. The reduction in correlation reduces crosstalk. The transmission characteristic may be one or more of time delay, scrambling, inversion or modulation.
