PROCEDE ET DISPOSITIF POUR LA TRANSMISSION DE SIGNAUX ANALOGIQUES AU MOYEN D'UN SYSTEME DE TRANSMISSION UTILISANT DES LIGNES DE TRANSMISSION OPTIQUE

摘要

The invention concerns a device comprising: a voltage/frequency converter (3 to 7) which receives the input voltage and emits pulses of a frequency proportional to this voltage; an electro-optical converter (8) which transforms the electrical pulses into light pulses; an optical transmission line (L) to the input of which the light pulses are applied; an opto-electronic converter (8') which transforms the light pulses at the output of the line (L) into electrical pulses; a counter circuit (9) enabling digital data representative of the input voltage to be supplied; and a digital-analogue converter (11) which transforms the digital data into analogue output data. The invention is used in data transmission in which the data transmitted are critical and do not tolerate interference well.
