Method for testing quality of optical network components

摘要

A method of testing the quality of a component in an optical network (10), comprises the steps of: (a) introducing a first calibrated reflector (15) at a location on an optical fibre (14) immediately before or in place of the component (16) to be tested; (b) measuring the reflection Ro from the first calibrated reflector (15) on the optical fibre (14); (c) replacing the first calibrated reflector (15) on the optical fibre (14) with the component (16); (d) connecting a second calibrated reflector (19) after the component (16); (e) measuring the reflection R2, from the second calibrated reflector (19); and (f) calculating the loss Lc through the component (16), by comparison of the reflections Ro and R2
