Abstract

CABLES DE FIBRAS PROVISTOS DE PROTECCION CONTRA LA ABSORCION DE HIDROGENO GASEOSO POR PARTE DE DICHAS FIBRAS OPTICAS. CONSTAN DE UN NUCLEO OPTICO (2) FORMADO POR VARIAS FIBRAS OPTICAS (10) REUNIDAS ALREDEDOR DE UN ELEMENTO (12) RESISTENTE A LA TRACCION, PUDIENDO DICHO NUCLEO CONTENER DIVERSOS ELEMENTOS RESISTENTES A LA TRACCION ASI COMO ELEMENTOS AUXILIARES; DE UNA O MAS CINTAS (14) QUE ENVUELVEN AL NUCLEO OPTICO (2), PUDIENDO EXISTIR ENTRE DICHA FUNDA (16) Y EL NUCLEO OPTICO (2) UN RELLENO CON FUNCIONES MECANICAS Y UN TAPONADOR (21) CONTRA LA INFILTRACION DEL AGUA.FIBER CABLES PROVIDED WITH PROTECTION AGAINST THE ABSORPTION OF GASEOUS HYDROGEN BY SUCH OPTICAL FIBERS. THEY CONSIST OF AN OPTICAL CORE (2) FORMED BY SEVERAL OPTICAL FIBERS (10) GATHERED AROUND AN ELEMENT (12) RESISTANT TO TRACTION, SAID CORE MAY CONTAIN VARIOUS ELEMENTS RESISTANT TO TRACTION AS WELL AS AUXILIARY ELEMENTS; OF ONE OR MORE TAPES (14) SURROUNDING THE OPTICAL CORE (2), MAY EXIST BETWEEN SAID COVER (16) AND THE OPTICAL CORE (2) A FILLER WITH MECHANICAL FUNCTIONS AND A PLUG (21) AGAINST WATER INFILTRATION.
