Abstract

IMPULSAR AL MOLDE BASE EN UN CONDUCTOR DE ONDA DE LUZ MONOMODE NO ES NADA PROBLEMATICO, SI PARA ELLO SE UTILIZA UN LASER, CUYA LONGITUD DE LA ONDA DE FUNCIONAMIENTO ESTA POR ENCIMA DE LA LONGITUD DE LA ONDA LIMITE DEL CONDUCTOR DE LA ONDA DE LUZ. ESTE LASER ES MOMENTANEAMENTE MUY CARO. ESPECIALMENTE EN LA UTILIZACION DENTRO DEL CAMPO DE CONEXION DEL ABONADO, EN EL CUAL Y POR MOTIVOS DEL TRAYECTO DE TRANSMISION RELATIVAMENTE CORTO SE DEBE TENER EN CONSIDERACION UNA CIERTA ATENUACION. POR LO CUAL SE ACONSEJA LA UTILIZACION DE UN LASER (6) MAS ECONOMICO, CUYA LONGITUD DE LA ONDA DE FUNCIONAMIENTO ESTA POR DEBAJO DEL CONDUCTOR DE ONDA DE LUZ (10) QUE CONECTADO A LA LONGITUD DE LA ONDA LIMITE. LA IMPULSION DEL MOLDE BASE SOLO ES POSIBLE CON ESTE TIPO DE LASER (6). TIENE UNA CAJA MODULO (1) DE UNA SOLA PIEZA DE METAL, EN LA CUAL, EL LASER (6) ESTA TRANSVERSAL AL EJE MEDIO DE LA CAJA (1). EXISTE UNA OPTICA DE IMAGEN MAYOR (9). CON EL AUMENTO SE CONSIGUE UNA DISMINUCION DEL ANGULO QUE SE ENCUENTRADEBAJO DE ESTE EN CONEXION CON LA LUZ LASER SOBRE LA SUPERFICIE FRONTAL DEL CONDUCTOR DE ONDA DE LUZ (10). ESTE ANGULO ES COMO MAXIMO IGUAL QUE EL ANGULO DE ACEPTACION DEL CONDUCTOR DE ONDA DE LUZ (10). EL CONDUCTOR DE ONDA DE LUZ (10) SE LLEVA DE FORMA COAXIAL A UN TALADRO CILINDRICO (5) Y SE AJUSTA Y SE FIJA POR UN ACOPLAMIENTO OPTIMAL AXIAL.
