METHOD AND DEVICE FOR OPTICAL DATA TRANSMISSION

摘要

The invention relates to a method and device for optical data transmission, in particular a method for transmission of data by means of digitised infrared signals. Data sequences are transmitted using a time-division multiplex access protocol with communication frames comprising single sequential windows with a given minimal bit transmission rate. At least one control impulse sequence is provided in each communication frame. According to the invention, the control impulse sequence is transmitted at a bit transmission rate which is lower than the minimum bit Transmission rate for the data sequence.
