Abstract

PROCEDIMIENTO DE FABRICACION DE ACOPLAMIENTOS OPTICOS POR FUSION, CON POLARIZACION SELECTIVA (1), LOS CUALES PRESENTAN VARIAS FIBRAS DE ENTRADA Y DE SALIDA Y QUE ESTAN CONSTITUIDOS EN LA REGION DE ACOPLAMIENTO (ZONA DE FUSION 6) POR FIBRAS MONOMODO PARALELAS, DEL TIPO MATCHED CLADDING, QUE NO PRESENTAN DOBLE REFRACCION. SEGUN DICHO PROCEDIMIENTO, ANTES DE LA FUSION DE LAS FIBRAS, SE HACE LLEGAR A UNA DE LAS FIBRAS DE ENTRADA (2) LUZ POLARIZADA LINEALMENTE DE UNA DETERMINADA LONGITUD DE ONDA, QUE ES DETECTADA EN LOS EXTREMOS DE LAS FIBRAS DE SALIDA (3) Y A CONTINUACION SE FUNDEN ENTRE SI LAS FIBRAS, AL TIEMPO QUE SE ESTIRA EL ACOPLAMIENTO HASTA QUE EL SOLAPAMIENTO ENTRE LAS DOS FIBRAS SE ESTANCA, DESCONECTANDOSE DESPUES LA FUENTE DE CALOR. DE ESTE MODO SE OBTIENEN ACOPLAMIENTOS POR FUSION (1) CON TRAMOS DE TRACCION DE SOLO UNOS 10 A 15 MM.
