Abstract

RED ANULAR OPTICA PASIVA UNA RED MALLADA ANULAR OPTICA QUE CONSTA DE UNA PLURALIDAD DE ANILLOS OPTICOS (11A, 11B, 11C, 11D) ACOPLADO CADA UNO DE ELLOS A AL MENOS OTRO ANILLO MEDIANTE UN ACOPLADOR OPTICO CORRESPONDIENTE (12). LOS ANILLOS (11A, 11B, 11C, 11D) TIENEN UNA PLURALIDAD DE NODOS DE ENTRADA/SALIDA CONSTITUIDOS POR ACOPLADORES OPTICOS (13). LOS NODOS ESTAN COLOCADOS DE TAL MANERA QUE, Y SU NUMERO ES TAL QUE, LA LONGITUD DE LA TRAYECTORIA OPTICA ENTRE CUALQUIER PAR DADO DE NODOS INCLUYE N ACOPLADORES DONDE N ES MENOR QUE EL NUMERO DE NODOS.
