摘要： PROBLEM TO BE SOLVED: To provide an inspection method for accurately inspecting flaws on an end face of an optical fiber and chippings of its circumferential end edge.
SOLUTION: This inspection method includes: a reflected-light inspection process R for performing inspection by irradiating the end face 31 to be inspected of the optical fiber 30 with light F and using reflected light from the end face 31; and a transmitted-light inspection process T for inspecting the end face 31 by irradiating the other end face 12 on the opposite side to the end face 31 with the light F, allowing the light to pass through the optical fiber 30, and using the transmitted light FT.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber bundle which is satisfactory in workability during the manufacturing and which can suppress deterioration in quality and also to provide a manufacturing method of the same.
SOLUTION: The optical fiber bundle 10 is provided with a bundle body 11 composed of a bundle of a plurality of coated optical fibers 14 each having an optical fiber 13 and a coating part 15 covering the optical fiber 13, and with bundling fixtures 12a, 12b externally fitted to at least one end of the bundle body 11. The bundle body 11 includes a tip section 18 composed of the bundle of optical fibers 13 without having the coating part 15, and a base end section 19 composed of the bundle of coated optical fibers 14 having the coating part 15 continuous to the tip section 18. The plurality of optical fibers 13 constituting the tip section 18 is bundled with an adhesive, while the plurality of coated optical fibers 14 constituting the base end section 19 is bundled with a bundling means 20.

摘要： PROBLEM TO BE SOLVED: To obtain an extrusion molding machine for manufacturing a coaxial cable without lowering transmission characteristics. SOLUTION: An inner conductor 1 has a crosshead 5 including a rotor K traveling in its hole 19. The extrusion molding machine forms a cordelle string 2 obtained by spirally winding a resin extruded from one extruder on an outer peripheral side of the conductor 1, and an insulating tube 3 for covering the conductor 1 and the string 2. A distribution unit 29 for distributing the resin for the string and the tube is provided at the rotor K near a resin injection port 21 of the crosshead 5. And, the resin is extruded from independent two channels via the unit 29.
