1. A method of optically encoding data for transmission over a wavelength division multiplexed optical communications system comprising the steps of:

  • generating a periodic series of optical pulses defining a series of time slots, wherein one pulse appears in each time slot;

    filtering the pulses to produce carrier pulses extending over more than one time slot; and

    modulating the pulses with data for transmission;

    wherein the filter gives rise to the pulses having a temporal profile with a minimum substantially in the center of each of the time slots adjacent to the time slot for that pulse.
