摘要： A single-core optical fiber cord (1) of less than 1.2 mm in cladding diameter includes an optical fiber core (2) covered with plastic, a fiber layer (3) surrounding the optical fiber core and acting as a tension member, and a cladding layer (4) consisting of flame retardant nonhalogen resin. The flame retardance, mechanical properties and handleability of the optical fiber are maintained even though its diameter is below 1.2 mm.

摘要： PROBLEM TO BE SOLVED: To provide a terminal structure of an optical fiber cord, that is capable of suppressing bendings in the terminal region of the optical fiber cord.
SOLUTION: With a boot 18 provided on the optical fiber inserting end of an optical connector 10, an end of an optical fiber cord 1 is fixedly inserted into the optical connector through the optical fiber cord inserting hole 9 of the boot 18. The outer circumference of the optical fiber cord 1 on a side to be inserted through by the optical connector 10 is covered with a linear reinforcing pipe 11 fitted to the outer circumference. One end of the reinforcing pipe 11 is fixedly press-fitted, without using an adhesive, to the middle of the optical fiber cord inserting hole 9 of the boot 18, while the other end of the reinforcing pipe 11 is extended outwardly from the boot 18 to protect the optical fiber cord 1. The extended length of the reinforcing pipe 11 from the boot 18 is set to a long that can suppress the bending of the optical fiber cord 1 at the entrance of the optical fiber cord inserting hole 9 in the boot 18.

摘要： A mono-fiber type optical fiber cord comprising: a coated optical fiber which is an optical fiber with a fiber coat therearound, a synthetic resin coat having a substantially rectangular sectional surface for further covering the coated optical fiber, and a reinforcing member within the coat for coated optical fiber, wherein the reinforcing member is located along one of the shorter sides of the coat in the substantially parallel direction with the shorter sides in such a manner as to be embedded along the longitudinally extending direction of the coated optical fiber. An optical cord ribbon is formed by mutually bonding the longer sides of the adjacent substantially rectangular sectional surfaces of a plurality of the mono-fiber type optical fiber cords, and thereafter by coating the external surface of the thus aligned optical fiber cords by a bundling coating method.
