Abstract

UN CABLE (20) DE FIBRA OPTICA INCLUYE UN NUCLEO (21) QUE COMPRENDE UNA PLURALIDAD DE UNIDADES 22-22. CADA UNIDAD SE FORMA CON UNA PLURALIDAD DE FIBRAS OPTICAS (24-24), LAS CUALES ESTAN ENSAMBLADAS JUNTAS SIN UN PRETENDIDO TRENZADO. CADA UNA DE LAS FIBRAS OPTICAS INCLUYE UN NUCLEO, REVESTIMIENTOS INTERIOR Y EXTERIOR CON EL REVESTIMIENTO INTERIOR CARACTERIZADO POR UN INDICE DE REFRACCION MAS BAJO QUE EL REVESTIMIENTO EXTERIOR. LA PROPORCION DEL DIAMETRO DEL REVESTIMIENTO INTERIOR AL DIAMETRO DEL NUCLEO Y LA PROPORCION DE DIFRENCIA EN LOS INDICES DE REFRACCION DE LOS REVESTIMIENTOS INTERIOR Y EXTERIOR A LA DIFERENCIA EN INDICES DE REFRACCION ENTRE EL NUCLEO Y EL REVESTIMIENTO INTERIOR SON TALES QUE CADA FIBRA OPTICA ES CAPAZ DE OPERACION EN UN MODO UNICO, EN UNA PREDETERMINADA LONGITUD DE ONDA. TAMBIEN LA DIFERENCIA ENTRE LOS INDICES DE REFRACCION DEL NUCLEO Y EL REVESTIMIENTO INTERIOR ES SUFICIENTEMENTE ALTA COMO PARA CAUSAR QUE CADA FIBRA SEA SUSTANCIALMENTE INFLEXIBLE A MICROFRICCIONES. LA PLURALIDAD DE UNIDADES SE ENCIERRAN EN UN TUBO COMUN (34), LO CUAL PROPORCIONA UNA DENSIDAD DE EMPAQUETAMIENTO PREDETERMINADA. EN UNA REALIZACION, UN MATERIAL DE OBSTRUCCION (46) SE DISPONE DENTRO DEL TUBO PARA LLENAR LOS INTERSTICIOS ENTRE LAS FIBRAS OPTICAS Y ENTRE LAS UNIDADES. EL MATERIAL DE OBSTRUCCION ES TAL QUE SU TENSION DE FLUENCIA CRITICA NO EXCEDE 70 PA A 20 GRADOS CENTIGRADOS Y TAL QUE TIENE UN MODULO A CORTADURA DE MENOS DE ALREDEDOR DE 13 KPA A 20 GRADOS CENTIGRADOS. EL TUBO COMUN SE ENCIERRA CON UN SISTEMA DE BAINA. ESTA DISPOSICION ES TAL QUE EL TRABAJO DEL CABLE, DESDE UN PUNTO DE VISTA OPTICO, NOS DEGRADA A TEMPERATURAS TAN BAJAS COMO -40 GRADOS F.
