Patent ID: 8111959

Claim:
A method making a fiber optic subassembly including an optical fiber and an optical detector, the method comprising: coupling a light source to a first end of the optical fiber enabling light energy from the light source to be transmitted from the first end through the optical fiber to a second end of the optical fiber; positioning the second end of the optical fiber relative to the optical detector; measuring an output signal output by the optical detector; adjusting the position of the second end of the optical fiber relative to the optical detector to align the second end of the optical fiber with respect to the optical detector at a position that corresponds to a relative peak signal output of the optical detector; while holding the second end of the optical fiber in a constant position relative to the optical detector, manipulating a remote portion of the optical fiber and monitoring the output signal of the optical detector to confirm that the output signal of the optical detector is stable during manipulation; and fixing the second end of the optical fiber to the optical detector.
