Title
(EN) WAVELENGTH DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK FOR PROVIDING BOTH OF BROADCASTING SERVICE AND COMMUNICATION SERVICE AND CENTRAL OFFICE USED THEREOF
(FR) RESEAU OPTIQUE PASSIF A MULTIPLEXAGE PAR REPARTITION EN LONGUEUR D'ONDE DESTINE A FOURNIR UN SERVICE DE RADIODIFFUSION ET UN SERVICE DE COMMUNICATION ET CENTRAL ASSOCIE
Abstract
(EN)
Disclosed is a wavelength division multiplexing passive optical network for simultaneously providing a broadcasting service and a data service by employing a broadband light source, which uses mutually injected Fabry-Perot laser diodes, as well as a central office used for the same.
(FR)
L'invention concerne un réseau optique passif à multiplexage par répartition en longueur d'onde destiné à fournir simultanément un service de radiodiffusion et un service de données par utilisation d'une source de lumière à large bande, laquelle utilise des diodes laser Fabry-Pérot à injection mutuelle, ainsi qu'un central associé.
