Abstract

LAS CURVAS DE LAS FIBRAS OPTICAS (14) SE PUEDEN MINIATURIZAR A BASE DE REDUCIR EL DIAMETRO DE UNA SECCION (18) DE LA FIBRA EN LA REGION DONDE SE DESEA LA CURVA (20). EN UN ASPECTO DE LA INVENCION, EL RADIO DE CURVATURA ES MENOR DE 100 MICRAS Y SE CONSIGUE UNA PERDIDA DE POTENCIA OPTICA MUY BAJA. UNA FIBRA CON UN DIAMETRO MUY REDUCIDO (FIG. 1D, SECCION B-B) SE PUEDE RETORCER TAMBIEN ALREDEDOR DE SU EJE LONGITUDINAL A UN GRADO MAYOR QUE UNA LONGITUD COMPARABLE DE UNA FIBRA DE DIAMETRO MAYOR. EN OTRO ASPECTO DE LA INVENCION, NO SE NECESITA REDUCIR EL AREA DE SECCION TRANSVERSAL DE LA FIBRA. LAS SECCIONES CURVAS DE LA FIBRA SE RECUECEN TERMICAMENTE FORMADO CURVAS SIN ESFUERZOS CON UN RADIO DE CURVATURA MINIMO PARA APLICACIONES A LARGO PLAZO. SE PUEDE PROCESAR CUALQUIER FIBRA OPTICA CON ELEMENTOS DE REESTIRAMIENTO Y/O QUIMICOS PARA FORMAR TAL CURVATURA O RETORCIMIENTO. LAS REGIONES TOLERANTES A LA CURVATURA O EL RETORCIMIENTO Y LAS CURVAS RECOCIDAS SE PUEDEN EMPAQUETAR POR SEPARADO O HACER QUE FORMEN PARTE SOLIDARIA DE UNA AMPLIA GAMA DE COMPONENTES DE FIBRAS OPTICAS, DETECTORES, REDES O SISTEMAS LO QUE HACE QUE SE AHORRE UNA CANTIDAD SIGNIFICATIVA DE ESPACIO, CON MAYORES PARTICULARIDADES DE COMPORTAMIENTO Y MAYOR FLEXIBILIDAD MECANICA.
