Abstract
EL TRANSMISOR DE VALORES DEL LUGAR OPTICO DE FIBRAS MUESTRA UN CARRETE DE FIBRA DEL CONDUCTOR DE LUZ (1.2) CON AL MENOS UNA POSICION DEL BOBINADO, DENTRO DE LAS ESPIRAS VECINAS LOS TRAMOS DE LA FIBRA DE CONDUCTOR DE LUZ SON IGUAL DE LARGOS. UN DEDO DE PRESION (2.2), QUE ESTA UNIDO CON UN SOPORTE DE CARRERA (2) MECANICO, SE LLEVA SOBRE LA POSICION DEL BOBINADO Y SE EJERCE EN UNA POSICION ESTRECHA DE LA FIBRA DE CONDUCTOS DE LUZ DE UNA ESPIRA UNA PRESION MECANICA, COMPARATIVAMENTE, POR LO CUAL SE PRODUCE UN EFECTO MICROBENDING EN LA FIBRA DE CONDUCTOS DE LUZ. UNA INSTALACION OPTOELECTRONICA EMISORA - RECEPTORA, QUE ESTA CONECTADA CON LA FIBRA DEL CONDUCTOR DE LUZ, AVERIGUA EL LUGAR, QUE SE ORIGINA A TRAVES DEL DEDO DE PRESION (2.2) DE LA POSICION DE PRESION Y CON ESTO LA POSICION DEL DEDO DE PRESION TAMBIEN (2.2).
