A method for scrambling a polarization of light signals, comprising the steps of scrambling the polarization of a light signal with a scrambling frequency, and combining the polarization scrambled light signal with at least one other light signal to form a wavelength division multiplexed light signal. The step of scrambling comprises the steps of scrambling the polarization of a first light signal with a first scrambling frequency, and scrambling the polarization of a second light signal with a second scrambling frequency which is different from the first scrambling frequency. The step of combining comprises combining the first and second polarization scrambled light signals to form the wavelength division multiplexed light signal. Such scrambling suppresses non-linear optical effects during transmission, such as four wave mixing and cross-phase modulation.
