Abstract

EL ELEMENTO DE FIBRA OPTICA COMPRENDE AL MENOS UN ALOJAMIENTO PARA LA MISMA CONSTITUIDO POR (A) UN MATERIAL POLIOLEFINICO PROVISTO DE AL MENOS UN ADITIVO QUE LO PROTEGE CONTRA LA DEGRADACION DEBIDO A LA OXIDACION, EL CALOR O LA PROXIMIDAD DE METALES, Y (B) AL MENOS UN AMORTIGUADOR DE ABSORCION-H2. EL ADITIVO SE SELECCIONA DEL GRUPO QUE COMPRENDE ANTIOXIDANTES, ESTABILIZADORES Y DESACTIVADORES METALICOS Y QUE REDUCE LA CAPACIDAD DE ABSORCION DE HIDROGENO A MENOS DEL 30% EN EL O EN CADA AMORTIGUADOR DE ABSORCION-H2 CUANDO EL O CADA AMORTIGUADOR HA ESTADO EN CONTACTO CON LA POLIOLEFINA QUE CONTIENE EL O CADA ADITIVO DURANTE 30 DIAS A 100 C EN UNA ATMOSFERA DE AIRE SATURADO CON VAPORES DE AGUA A 150 MBARS.
