Patent ID: 8014640

Claim:
A method comprising: robotically moving a photo detector to a particular optical fiber, of a plurality of optical fibers secured at least one end by a fiber tension device, where the fiber tension device provides slack in a first portion of each of the plurality of optical fibers and the photo detector is moved to a position adjacent to a second portion of the articular optical fiber; fixing the particular optical fiber between cooperating surfaces of the photo detector and a fiber rail to cause the fiber tension device to extend the first portion of the particular optical fiber to take up the slack provided in the first portion of the particular optical fiber and form a bend in the second portion of the particular optical fiber; detecting, using the photo detector, light leakage in an area of the second portion of the particular optical fiber, where the light leakage at least partially results from forming the bend in the second portion of the particular optical fiber; and determining, based on the detected light leakage, signal strength transmission associated with the particular optical fiber.
