Реферат: A method of synchronising an optical transmitter and modulator comprising transmitting a calibration sequence of pulses from the transmitter to the modulator; varying a control timing drawn from the set comprising the transmit interval timings and the modulator transmission interval timings; monitoring the resulting pulses transmitted by the modulator and selecting a preferred control timing; controlling the optical transmitter and/or modulator responsive to the selected control timing. Corresponding apparatus, systems, signals and programs for computers to implement or control the arrangement are also provided.
