This invention makes use of focusing lens in combination with a coupler region to expand and collimate the output from a single fiber so that optical radiation may be coupled from one fiber to another and coupled off to a separate line. A mirror or mirrors may be positioned at a 45 degree angle to the axis of the optical path to couple out a fraction of the radiation to other lines.
