Fiber optic end-face transparent protector system and method

A protective assembly method using a transparent layer within the fiber interconnect system aids in optical coupling by preventing an air gap from forming between the fiber cores within a connector. A thin transparent film (or with adhesive) is placed over the fiber end-faces at the connector interface, the film having characteristics which allows it to conform to the fiber end and minimize coupling loss between fibers.
