Abstract

UN CABLE DE FIBRAS OPTICAS (20) QUE INCLUYE ACCESORIOS PARA EN EL NUCLEO DEL MISMO PARA PREVENIR QUE EL AGUA FLUYA LONGITUDINALMENTE A LO LARGO DEL NUCLEO Y PARA PREVENIR LA CONGELACION DE TAL AGUA. LOS ACCESORIOS PARA PREVENIR LA CONGELACION DEL AGUA DENTRO DEL NUCLEO, LO CUAL AFECTARIA DE MANERA ADVERSA A LAS FIBRAS OPTICAS, INCLUYE UN MATERIAL ANTICONGELANTE. SE PUEDEN IMPREGNAR DOS CINTAS CON UN MATERIAL ANTICONGELANTE TAL COMO, POR EJEMPLO, PROPILENGLICOL Y SE PUEDE UTILIZAR PARA OBTENER UN MATERIAL ESTRATIFICADO CON UN POLVO SUPERABSORBENTE ENTRE MEDIAS. RESULTA VENTAJOSO QUE EL CABLE SEA IGNIFUGO DE MODO QUE SE PUEDA EXTENDER SALIENDO DE UNA CAMARA SUBTERRANEA EXTERIOR HASTA LOS PUNTOS DE DISTRIBUCION DE UN EDIFICIO.
