Abstract

El método descrito para la fabricacion de fibra optica (43) involucra aplicar a la fibra, en forma alternada, un giro en el sentido del movimiento de las manecillas del reloj, y otro en sentido contrario, a medida que la fibra se estira a partir de un material preformado (41), de tal forma que se imprime o imparte, sobre la fibra, un espín o giro permanente. El toque o momento torsor se aplica a través de medios novedosos, a decir, un rodillo (15) de una geometría tal que cause que la fibra ruede sobre la superficie del rodillo, en forma alternada, en una direccion opuesta. La novedosa técnica puede facilitar el estiramiento de fibra de baja dispersion del modo de polarizacion (baja DMP) a una velocidad relativamente alta.
