Abstract

UN DESPOLARIZADOR OPERA DIVIDIENDO LA LUZ QUE VIAJA A LO LARGO DE UNA FIBRA OPTICA (12) EN DOS SUB-HACES. UNO DE LOS SUB-HACES SE INSERTAN EN EL INTERIOR DE UN BUCLE DE RECIRCULACION (28), EN DONDE TIENE SU ESTADO DE POLARIZACION ALTERADO. LA LUZ EN EL BUCLE DE RECIRCULACION (28) SE REINSERTA ENTONCES EN EL INTERIOR DE LA FIBRA EN UNA POSICION ANTERIOR A LA QUE SE PRODUJO LA DIVISION.
