Abstract
An optical branching unit and method for producing the unit which comprises an optical branching element having a body portion with at least one surface having the waveguides extending thereto, said surface and the waveguides being polished optically flat to extend perpendicular to the longitudinal axis of the waveguides, each of the units being secured in a housing, which has a port associated with each optical waveguide and a device for receiving and holding an external waveguide being axially aligned with the axis of each optical waveguide so that an external waveguide can be held in an abutting and aligned contact with the polished optical waveguide of the polished optical flat surface to form an optical waveguide communication with the waveguide of the branch element.
