Abstract

La presente invencion se refiere a un aparato y método que proporcionan señales de multiples longitudes de onda utilizando una fuente de banda amplia optica simple, para generar muchos canales de longitud de onda optica independiente. Un transmisor optico incluye un dispositivo de compresion de pulsos que separa los componentes de frecuencia de pulsos opticos periodicos en el dominio de tiempo que forman canales de longitud de onda separados que se modulan separadamente por un modulador optico de banda amplia de alta velocidad. Un receptor incluye un separador pasivo para separar los canales de longitud de onda individuales. El transmisor de pulso comprimido puede ajustarse convenientemente para proporcionar traslape optimo de canales de longitud de onda con los espectros de canal moduladores.
