Abstract
A multiplexed transmission system using external electro-optic modulation of a CW multimode laser diode is described. The system relies on a novel multiplexing method wherein path differences larger than the source coherence length act as independent signal carriers. The performances of the system are described in the frame of analogue transmission of video signals.
