Abstract
An optical fiber coupler reinforcing member comprises an approximately rectangular member formed by a hard material, and has a flat surface along the longitudinal direction thereof. In addition, the shape thereof in cross-section is a hexagonal shape which inscribes a cylindrical member. Furthermore, a recess having a U-shaped cross-section is formed in the longitudinal direction of the above-mentioned approximately rectangular member and houses coupling section. The coupling section housed within the recess is fixed at both ends of the recess by an adhesive or the like. In addition, both ends of the inner wall surface of the recess have been given bevel sections. As a result, the optical fiber coupler reinforcing member having high reliability at low cost, with which the strength with respect to external force is improved and with which processability and the assembly operations of the optical fiber coupler are easy, are provided.
