Abstract
El sistema permite la medida de redes de sensores de fibra optica en redes opticas pasivas, mediante la utilizacion de láseres sintonizables de semiconductor operando en régimen de onda continua. Concretamente el láser sintonizable (2), con su correspondiente controlador (3) y a través de un circulador (4), envía senales de una determinada longitud de onda a la red pasiva (1) de sensores opticos durante un período T1, tras el que cambia de longitud de onda, recibiéndose las senales reflejadas en la red de sensores en un conversor electro optico (6), perfectamente a través de un filtro (5) de banda eliminada, que rechaza la banda ôoffö.The system allows the measurement of fiber optic sensor networks in passive optical networks, through the use of tunable semiconductor lasers operating in a continuous wave regime. Specifically, the tunable laser (2), with its corresponding controller (3) and through a circulator (4), sends signals of a certain wavelength to the passive network (1) of optical sensors during a period T1, after which The wavelength changes, with the signals reflected in the sensor network being received in an electro-optical converter (6), perfectly through a eliminated band filter (5), which rejects the ôoffö band.
