A line transmission system comprises n optical signal modulators (1-4) for modulating respective optical signals under the control of respective isochronous electrical signals (DI). Multiplexing means (7-14) is provided for time division multiplexing the modulated optical signals to generate a multiplexed output signal so that multiplexing is carried out in the optical domain.read more
