Abstract

METODO PARA FABRICAR UN ATENUADOR PREAJUSTADO DE FIBRA OPTICA DE MODO SIMPLE Y ATENUADOR PREAJUSTADO. COMPRENDE: A) UNIR POR FUSION LOS DOS TERMINALES DE UN TUBO ALARGADO DE FIBRA DE CRISTAL A LOS TERMINALES DE LOS EXTREMOS DE UNA FIBRA DE CRISTAL DE MODO SIMPLE; B) CALENTAR SUAVEMENTE UNA PORCION DEL FRAGMENTO INTERMEDIO DE LA UNION; C) ALINEAR LOS EXTREMOS SEPARADOS DEL FRAGMENTO INTERMEDIO CALENTADO, PARA AJUSTAR JUSTAMENTE EL VALOR DE LA ATENUACION DEL ATENUADOR; D) ASEGURAR LOS EMPALMES AJUSTADOS POR UN ADHESIVO; Y E) RECUBRIR A LOS EMPALMES CON UNA CUBIERTA PROTECTORA. CONSTA DE: DOS FIBRAS OPTICAS (1, 4), UN EMPALME (3); UNA CUBIERTA PROTECTORA DE FIBRA DE ACERO Y DOS REVESTIMIENTOS PALSTICOS (51, 52).
