Method to change reflectance of an end of an optical fiber

Abstract

A level of reflectance of an optical signal by an end of an optical fiber is effected by providing a terminating component at an end of the fiber which provides a first level of reflectance and by bringing into engagement a movable component which allows the optical signal to enter the movable component and to have a second level of reflectance which is different from the first level of reflectance. The movable component comprises a ferrule which provides the second level of reflectance at the end face. Thus in one arrangement the fiber is terminated by a perpendicular face which is reflective and the movable component has a non-reflecting end. Or in the alternative the fiber is terminated by an angled face which is non-reflective and the movable component has a reflecting end.
