Abstract

In order to achieve the optimum optical performance of fiber optic connectors, it is critical that there be good physical contact at the fiber-to-fiber interface. Loss of physical contact results in increased insertion loss and reflectance. Today's connectors are designed to have mating surfaces with tightly controlled endface geometries to ensure physical contact during temperature variations and repeated matings. However, material degradation of the fiber, ferrule, or the adhesive which holds the fiber into the ferrule, can change the endface geometry and cause eventual failure of the connector. Tests have been developed or are under development to quantify mechanical changes in these materials, including adhesive creep, fiber pistoning, ferrule deformation and roughening, and fiber deterioration. This paper will describe the latest test results acquired from applying these procedures.
