The patent application concerns an optical coupler for use in an optical path defined by a single fiber optic filament. This coupler uses first and second rod gradient index positive lens elements positioned in the optical path and which have a central member optically abutted between the rod gradient index positive lens elements. It is an object to provide an efficient optical coupler for use in a data bus employing single fiber optic cable which may be used in optical communications network systems.
