Abstract
ENLACE OPTICO DE TRANSMISION CON DETECCION DE INTRUSION. CONSTA DE FIBRAS OPTICAS DE TRANSMISION DE INFORMACIONES Y DE MEDIOS DE DETECCION DE INTRUSION QUE INCLUYEN EQUIPOS TERMINALES EMISORES/RECEPTORES DE UNA SEÑAL DE VIGILANCIA DE INTRUSION. SE CARACTERIZA PORQUE COMPRENDE, ADEMAS, FIBRAS DE VIGILANCIA (4) MONTADAS SOBRE UNA FUNDA RANURADA INTERNA (10), QUE RODEA A LAS FIBRAS DE TRANSMISION (3), Y ARROLLADAS EN BUCLE EN LOS EXTREMOS DEL CABLE AL MENOS A TRAVES DE LOS EQUIPOS TERMINALES (2). EL INVENTO ES APLICABLE A CABLES ESPECIALES.
