DIRECTIONAL OPTICAL FIBER SIGNAL SAMPLING DEVICE

摘要

A directional optical fiber signal tapping assembly. A light pipe rod encircles and accepts stray light rays leaving the otherwise bare outer surface of a length of optical fiber in a region following a location having a bend that induces a selected degree of outward leakage of optical signal rays in the bend following longitudinal light pipe region. Curvature of one end of the light pipe rod conducts the extracted optical signal sample to an optical detector device.
