A reinforcement for reinforcing a joint at which two lengths of an optical-fiber cable consisting of at least one optical fiber are spliced by fusion welding, such that a spliced stripped part of each optical fiber and adjacent coated parts of the cable are secured to the reinforcement by an adhesive material. The reinforcement is formed of a transparent crystallized glass which has a major crystalline component consisting of Li2O, Al2O3 and SiO2 and which has a low coefficient of thermal expansion. The reinforcement has a contact surface which is roughened by machining and at which the reinforcement contacts the optical-fiber cable. A strengthened layer is formed by ion exchange, on an entire surface of the reinforcement, and an adhesive layer is formed on the rough contact surface, to secure the optical-fiber cable to the contact surface, upon heating of the adhesive layer, such that the adhesive material serves to smooth the rough contact surface, and thereby renders the rough contact surface transparent.

A reinforcement for reinforcing a joint at which two lengths of an optical-fiber cable consisting of at least one optical fiber are spliced by fusion welding, such that a spliced stripped part of each optical fiber and adjacent coated parts of the cable are secured to said reinforcement by means of an adhesive material, wherein the improvement comprises: a base formed of a transparent crystallized glass which has a major crystalline component consisting of Li2O, Al2O3 and SiO2 and which has a low coefficient of thermal expansion; said base having a rough contact surface which is roughened by machining and at which said base contacts said optical-fiber cable; a strengthened layer which is formed by ion exchange, on an entire surface of said base including said rough contact surface; and an adhesive layer which consists of said adhesive material and which is formed on said rough contact surface, said adhesive layer securing said optical-fiber cable to said base, upon heating of said adhesive layer, such that said adhesive material serves to smooth said rough contact surface, and thereby renders said rough contact surface transparent.
