ABSTRACT:
Coupler for joining two optical fibers to a third fiber, while preserving good optical isolation between the first two fibers. The coupler is preferably formed of an approximately index-matching plastic, and the fiber ends are cemented in place. The two fibers which are to be isolted are located parallel and adjacent to each other, and their ends are glued into an elongated hole on one side of the coupler. Opposite to this hole is a second hole into which the union fiber is seated. Epoxy glue is used to connect the fibers in place. Plastic fibers are preferably used.
