Abstract
UN CABLE DE COMUNICACIONES QUE CONTIENE UN NUCLEO DE MEDIOS DE TRANSMISION TALES COMO FIBRAS OPTICAS, POR EJEMPLO, DISPUESTOS EN UN TUBO CENTRAL Y UN SISTEMA DE VAINAS (32) QUE INCLUYE MEDIOS PARA IMPEDIR EL MOVIMIENTO DEL AGUA DENTRO DEL CENTRO DEL CABLE. PROVISIONES QUE BLOQUEAN EL AGUA (26) SE DISPONEN EN EL TUBO CENTRAL Y PUEDEN CONTENER UNA CINTA O UN HILO, POR EJEMPLO, O AMBOS. LA CINTA PUEDE TENER CINTAS INTERMEDIAS ENTRE LAS CUALES SE DISPONE UN MATERIAL SUPERABSORBENTE EN FORMA DE POLVO EL QUE AL CONTACTO CON EL AGUA SE HINCHA E INHIBE EL MOVIMIENTO DEL MISMO. EN OTRO MODO DE CONSTRUCCION, UN HILO QUE SE HINCHA CON EL AGUA SE PUEDE EXTENDER LONGITUDINALMENTE EN LINEA CON LAS FIBRAS OPTICAS EN EL CENTRO. LAS PROVISIONES QUE BLOQUEAN EL AGUA Y EL INDICE DE LA SUMA DE LA AREAS DE SECCION CRUZADA DE LAS FIBRAS OPTICAS Y DE LAS PROVISIONES QUE BLOQUEAN EL AGUA Y DE CUALQUIER OTRO ELEMENTO DEL CABLE DENTRO DEL CENTRO HASTA EL AREA DENTRO DEL TUBO CENTRAL SON TALES QUE LOS MEDIOS DE TRANSMISION EN EL CENTRO ESTAN SUSTANCIALMENTE SEPARADOS DEL SISTEMA DE VAINAS AL MENOS EN UNA DIRECCION TRANSVERSAL DEL EJE LINGITUDINAL DEL CABLE. POR OTRO LADO, EL MEDIO DE TRANSMISION ESTA UNIDO SUFICIENTEMENTE AL SISTEMA DE VAINAS EN LA DIRECCION LONGITUDINAL QUE PROVOCA EL MOVIMIENTO SUSTANCIAL DEL MEDIO DE TRANSMISION JUNTO CON EL SISTEMA DE VAINAS CUANDO AL CABLE SE LE APLICAN FUERZAS DE TRACCION.
