Directional optical fiber signal tapping assembly
First Claim
Patent Images
1. A directional optical fiber signal tapping assembly comprising:
- (a) first and second light pipes each including a groove;
(b) an optical fiber positioned in the grooves in said light pipes;
(c) a support member having a first opening therein with said first light pipe being fixed rigidly in said opening, said support member also having a second opening therein with positioning means supporting said second light pipe in said second opening such that said light pipes can be selectively displaced from each other in a longitudinal direction thereby selectively bending said optical fiber thereby changing the amount of light which is coupled into said light pipes due to leakage from said optical fiber.

Abstract
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.
