Abstract

LAS FIBRAS DE TRANSMISION OPTICA SIRVEN PARA TRANSMITIR SEÑALES SOBRE ALGUNA DISTANCIA. DICHAS FIBRAS HAN SIDO CONSTRUIDAS TRADICIONALMENTE DE FIBRA DE VIDRIO; CONSTAN DE UN NUCLEO CENTRAL Y UN CHAPADO EXTERIOR, UNA COPA BLANDA CIRCUNDANTE ALREDEDOR DE DICHA FIBRA Y UNA CAPA DURA ALREDEDOR DE LA CAPA BLANDA. A CAUSA DEL MATERIAL DE CONSTRUCCION, DICHAS FIBRAS TENIAN ALTAS PERDIDAS DINAMICAS. POR ALTERACION DE LOS MATERIALES UTILIZADOS ALREDEDOR DE LA FIBRA DE VIDRIO, LA PRESENTE INVENCION HA REDUCIDO ENORMEMENTE LA PERDIDA DINAMICA Y ADEMAS, HA MEJORADO NOTABLEMENTE LAS POSIBILIDADES PARA LA TRANSMISION DE SEÑAL. EL MATERIAL ORGANICO UTILIZADO PARA REALIZAR LA TRANSMISION, PUEDE VARIAR PERO EL EFECTO ES TAL QUE LA PERDIDA DINAMICA SE MANTIENE BAJA COMPARADA CON TECNICAS PREVIAS.
