Abstract

Il dispositivo di comando ottico per sistemi di monitoraggio di fibre ottiche di reti di telecomunicazioni presenta un deviatore ottico di per se noto e comprende un microprocessore destinato ad elaborare i segnali d'ingresso e a fornire al deviatore ottico le istruzioni d'indirizzo relative, un accoppiatore ottico, collegato all'ingresso del deviatore ottico e destinato a prelevare una parte del segnale ottico d'ingresso ad esso trasmessi, un fotorivelatore, connesso a detto accoppiatore ottico e a detto microprocessore, destinato a convertire i segnali ottici provenienti da detto accoppiatore ottico in impulsi elettrici e ad inviare a microprocessore, una coppia di commutatori identificatori, collegato al microprocessore. Il microprocessore, il fotorivelatore ed il deviatore ottico sono alimentati da un'unità d'alimentazione di energia.The optical control device for optical fiber monitoring systems of telecommunication networks has an optical diverter per se known and comprises a microprocessor intended to process the input signals and to provide the optic diverter with the relative address instructions, a coupler optical, connected to the input of the optical deviator and intended to take a part of the optical input signal transmitted to it, a photodetector, connected to said optical coupler and to said microprocessor, intended to convert the optical signals coming from said optical coupler into pulses electrical and to send to the microprocessor, a pair of identifier switches, connected to the microprocessor. The microprocessor, the photodetector and the optical diverter are powered by a power supply unit.
