ABSTRACT:
In a method for fixing a polarization-preserving optical fiber the fiber is illuminated transversely and orientation of the polarization-preserving plane of the fiber is monitored by direct visual examination of internal components of the fiber rendered visible by such illumination. The illumination is effected through the wall of a transparent ferrule holding the fiber. The method has applications in fiber optical telecommunications systems.
