OPTICAL FIBER RECEIVING MEMBER OF OPTICAL FIBER COUPLING DEVICE AND MANUFACTURE THEREOF

摘要

A process for making a fiber optic coupler. An optical fiber reception block of rigid material that has orthogonal longitudinal and transversal planes of symmetry, an arcuate fiber receiving groove extending along the longitudinal plane of symmetry, and a plurality of reference surfaces is provided. An optical fiber is glued into the groove and the block is cut along a plane perpendicular to the longitudinal and transversal planes of symmetry to remove part of the fiber. The block is then cut in half along the transversal plane of symmetry, the two halves are superimposed in inverted positions and aligned by using a reference surface. This process forms a multibranch coupler that finds numerous applications in telecommunication systems.
