Abstract
En la presente invención se describe, que la presencia de birrefringencia (típicamente no intencional) en la fibra óptica de modo único puede limitar severamente la utilidad de la fibra para, por ejemplo, los sistemas de comunicación de fibra óptica análoga o de alta velocidad de bitios, debido a la dispersión de modo de polarización (DMP) resultante. Ahora se ha descubierto que la DMP se puede reducir en forma substancial si, durante el estiramiento de la fibra (13), se aplica un par de torsión a la fibra de tal forma que se ejerza o imprima una 'rotación' o 'giro' sobre la fibra. Deseablemente el par de torsión se aplica de tal forma que el giro que se ejerce sobre la fibra no tiene una frecuencia espacial constante, por ejemplo, tiene una helicidad, alternativamente, en el sentido de las manecillas del reloj y en el sentido contrario. De conformidad con la invención, cuando menos una porción de la fibra óptica tiene un giro cuya frecuencia espacial excede 4 giros/metro.
