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.
