摘要： The present invention aims to prevent formation of defect or break-off at ridges of fixing grooves of optical fiber-fixing substrates (1) when an optical fiber is received in the fixing groove (3) or when an end surface of the substrate is polished by a grinding work. For that purpose, the ridges (4) of the fixing grooves of the substrate have a curvature of radius of not less than 5 µm over the entire portion of the ridges viewed in the lateral cross-sectional view of the fixing grooves. Preferably, the bottoms of the fixing grooves of the substrate have a curvature of radius of not more than 5 µm viewed in the lateral cross-sectional view of the fixing groove. The fixing grooves may be produced by press forming.

摘要： A method of inspecting V-shaped grooves, e.g. grooves for optical fibres, is carried out in the following steps. Coordinates of more than 20 points per groove (1) on a substate formed with V-shaped grooves ar emeasured with a stylus (3) moving in directions perpendicular to the longitudinal directions of the grooves. Data measured within regions of at least 10 µm at the edges (5) and bottom (6) of the grooves are removed from the data so obtained. Shapes formed by straight lines are then calculated on the basis of remaining data on effective measuring lengths of more than 40 µm. A method of working the V-shaped grooves is effected by the following steps. A circle (7) having a diameter substantially equal to that of fibres to be supported in the grooves is drawn inscribed in the interior of a V-shaped groove of shape calculated by the above method. The groove is then worked, while errors in the centre position of the circle are fed-back into the working process of the groove of the substrate to compensate for variation of depths and pitches of the V-shaped grooves being worked.

摘要： A reinforcement for reinforcing a joint at which two lengths of an optical-fiber cable (30) consisting of at least one optical fiber (30a) are spliced by fusion welding, such that a spliced stripped part (3l) of each optical fiber and adjacent coated parts (32, 32) of the cable are secured to the reinforcement (l, 2) 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 rough contact surface (3, 4) which is a 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 (3, 4, 5, 6) of the reinforcement. An adhesive layer (7, 8) 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.
