Abstract
The present invention is an optical fiber connector with an internal structure which allows the polarization axis of an optical element to be freely rotated and fixed with respect to an rotational orientation-indicating reference on an external surface of the connector. The reference then provides an external physical indication of the spatial direction of the birefringence axes of the optical element.
