ABSTRACT:
An optical device such as a branch element comprising a body having at least one port with each port being formed by an integral cylindrical guide plug extend from an outer surface of the body and coaxially receiving an optical waveguide such as a fiber with the end surface of the waveguide and the plug being coplanar. The optical device is made by assembling a plurality of parts having planar surfaces with the planar surfaces engaged with each other and with the parts having semi-cylindrical projections having a flat surface lying in the plane of the planar surfaces to aid in aligning the projections to form the guide plugs, the planar surfaces are provided with coacting adjustment portions comprising recesses receiving projections or posts.
