Abstract
EL INVENTO DESCRIBE UN PROCEDIMIENTO PARA LA TRANSMISION DE MENSAJES OPTICOS ENTRE EMISORES Y RECEPTORES SEPARADOS ESPECIALMENTE. SE APLICA EL PRINCIPIO DE LOS RECEPTORES HETERODINOS. UN PORTADOR OPTICO NO MODULADO DE UNOS LASERS DISPUESTOS EN LATERALES DE LOS RECEPTORES DISTRIBUYE EN DOS PORCIONES DE UNOS ACOPLADORES (KE) DE FIBRAS OPTICAS, LA TRAYECTORIA DE TRANSMISION (EMF) Y LA TRANSMISION LOCAL DEL LASER (LL). EN UNA RAMA SE EFECTUA UNA DESVIACION DE FRECUENCIA DE LA SUMA AF. EL PORTADOR OPTICO NO MODULADO RECORRE UNA FIBRA DE UN MODULO DE INTRODUCCION EN DIRECCION LATERAL AL EMISOR Y SE MODULA CON UNA SEÑAL UTIL EN UN MODULADOR (MOD). ESTA SEÑAL OPTICA MODULADA RECORRE DE NUEVO EL LATERAL DEL RECEPTOR, SE TRANSCONECTA CON LA TRANSMISION LOCAL DEL LASER (LL) EN UNA BANDA DE FRECUENCIA INTERMEDIA.
