Abstract

EN UN SISTEMA DE COMUNICACION OPTICA CON UN ACOPLADOR EN ESTRELLA PASIVO, LA MEDIDA NO DEBIERA INTERFERIR CON EL FUNCIONAMIENTO DE OTRAS ESTACIONES. LA MEDICION DE LA DISTANCIA SE EFECTUA MEDIANTE LA DETERMINACION DEL RETARDO DEL ECO. SE USA OTRA LONGITUD DE ONDA. EL SISTEMA USA UNA MULTIPLEXACION DE DIVISION DE TIEMPO Y LONGITUD DE ONDA COMBINADA. UNA LONGITUD DE ONDA SE MANTIENE SIEMPRE LIBRE DE MEDICIONES SI ELLO FUERA POSIBLE. PARA LA MEDICION, PUEDE USARSE EL MISMO FORMATO DE DATOS QUE EL QUE SE EMPLEA DURANTE EL FUNCIONAMIENTO NORMAL. LA MEDICION PUEDE REPETIRSE DE FORMA CONTINUA SIN CAMBIAR DURANTE SU FUNCIONAMIENTO.
