ABSTRACT:
An optical fiber termination of the expanded beam type in which the fiber end fits into one end of a glass ferrule whose other end is closed by a spherical lens. The ferrule is filled with an ultra-violet curing glue. The position of the fiber end is adjusted so that light from the fiber leaves the lens as a collimated beam and then the glue is cured by ultra-violet light injected, initially, via the lens to cure the glue at the fiber end and lens. Then the rest of the glue is cured by ultra-violet light applied through the wall of the ferrule.
