Patent ID: 7956992

Claim:
Method for testing the optical fiber connection quality of an optical drop fiber between a telecommunications system and a subscriber connection box in a multi-dwelling unit or other subscriber premises before connection to other subscriber equipment comprising the following steps: providing a fiber holding device having at least two main clamping sections arranged by a first of the main clamping sections independently operable from a second of the main clamping sections, the first main clamping section being undisturbed by subsequent clamping or unclamping of the second main clamping section; inserting a reflection-producing body in the first of the main clamping sections; placing the end of the optical drop fiber to be tested in the second main clamping section of the fiber-holding device, which holds the fiber end in alignment with the reflection-producing body; providing an optical signal from a direction of the telecommunications system which is reflected by the said reflection-producing body back towards the telecommunications system; and detecting the reflected signal by an instrument to confirm acceptable signalling quality of the optical path between the telecommunications system and the drop fiber end.
