Data transmission system for cars, has individual sources fed to multiplexer, for time or frequency division multiplexing of control area networks onto fibre optic link.

摘要

The data transmission system takes signals from several individual sources (11-16), via various Control Area Network (CAN) buses (21,22,23). These are fed to a multiplexer (3) which multiplexes them using time or frequency division multiplexing, for transmission over a fibre optic link (4). There is a signal splitting unit (5) including a filter (51) and a demultiplexer (52), to separate the buses (61,62,63) with receivers (71-76).
