Abstract
A method for making a multimode fiber optic subassembly includes alignment of an optical detector with a fiber termination of an optical fiber. The output of the optical detector (e.g. photocurrent) can be measured from light being transmitted through the optical fiber and detected by the optical detector. The end of the optical fiber and/or the optical detector can be positioned and angularly oriented in order to obtain relative maximum or peak output of the optical detector for a given position and orientation. The output of the optical detector can be monitored while mechanically manipulating, e.g. bending, flexing, shaking and/or twisting, the optical fiber, in order to verify that the positional relationship between the end of the optical fiber and the optical detector corresponds to a position and/or orientation that provides stable output from the optical detector. If the optical detector output is not stable, the end of the multimode optical fiber and the optical detector can be moved, changing the position and/or the orientation of one or both, until the output of the optical detector is stable during manipulation. If the optical detector output is stable, the end of the m…
