Abstract
A reinforcing apparatus for an optical-fiber coupler is formed by placing fused optical fibers into a grooved U-shaped base structure. A cover which has a different longitudinal length than the base structure is centered on top of the U-shaped base structure. There exists an exposed groove section of the U-shaped base structure which lies on either side of the cover. An adhesive is inserted into these exposed groove sections so as to fix the reinforcing casing and the optical-fiber coupler to each other.
