Abstract

UNA RED EN LA QUE NO SOLO LA TRANSMISION DE SEÑALES OPTICAS Y SEÑALES DE INFORMACION EN SECCIONES DE TRANSMISION (1,1A), SINO TAMBIEN LA CONMUTACION EN DISPOSITIVOS DE CONMUTACION (24) Y LA UNION O LA SEPARACION DE SEÑALES DE CONTROL Y SEÑALES DE INFORMACION TIENEN LUGAR EN EL CAMPO OPTICO. LAS SEÑALES DE CONTROL (C) Y LAS SEÑALES DE INFORMACION (D) EN EL CAMPO OPTICO SON DISTINGUIBLES ENTRE SI, Y AMBAS ESTAN ACOPLADAS CON CONEXION Y DESCONEXION EN EL MISMO CONDUCTOR OPTICO (1,1A). PARA DISTINGUIR LAS SEÑALES DE CONTROL DE LAS SEÑALES DE INFORMACION, LOS MODOS DE TRANSMISION (POR EJEMPLO, LA LONGITUD DE ONDAS O EL MODO DE POLARIZACION) DE LAS MISMAS PUEDEN SER DIFERENTES. ASIMISMO PUEDE REALIZARSE UNA DISTINCION ENTRE LA SEÑAL DE CONTROL Y LA SEÑAL DE INFORMACION MEDIANTE DIFERENTES DIRECCIONES DE TRANSMISION; PARA CONTROLAR UN DISPOSITIVO DE CONMUTACION, SE TRANSMITE UNA SEÑAL DE CONTROL AL DISPOSITIVO DE CONMUTACION A TRAVES DE UNA FIBRA DE VIDRIO, LA CUAL, A SU VEZ, SIRVE PARA LA TRANSMISION DE SEÑALES DE INFORMACION EN UNA DIRECCION OPUESTA.
