ABSTRACT:
A method for determining optical transmission characteristics and efficiencies in multi-path optical fiber networks which include, for example, inter-fiber couplings and optical components, includes introducing light energy into the entry port of the network, measuring the light energy at the network exit port or ports, exposing a portion of the light energy transmitting core in one of the optical paths of the network by, for example, removing the cladding from core, surrounding the exposed core with a material, such as a liquid, having an index of refraction greater than that of the exposed core to cause the light energy to escape and thereby quench light transmission, and remeasuring the light energy at the network exit ports. The change in energy transmission before and after light quenching is a measure of transfer characteristics of the selected optical path and related couplings.
