ABSTRACT:
A method for measuring attenuation of light signals passing through an opal fiber and means for effecting such measurements. The attenuation can be measured over varying angles of bend and with light of different wave lengths. The determinations made are of value in the evaluation of effects of bending optical fibers used in telecommunications, with certain sensors and the like.
