OPTICAL FIBER CABLE

PROBLEM TO BE SOLVED: To provide an optical fiber cable capable of maintaining a favorable property of taking out an optical fiber in intermediate point post-branching work when optical fiber units are formed using discrimination yarns made of a thermal adhesive material.SOLUTION: An optical fiber cable includes: a plurality of optical fiber units 1a, 1b, and 1c in which a plurality of discrimination yarns 12a to 12f made of a thermal adhesive material are wound around the circumference of a plurality of optical fibers 11a, 11b, and 11c, and which are tied in a bundle respectively by heat fusion of intersection points between the discrimination yarns 12a to 12f and are in a separated state each other; a slot core 2 having a slot groove 21 for housing the plurality of optical fiber units 1a, 1b, and 1c; a longitudinally attached tape 3 having a width shorter than the whole circumference of the slot core 2 and longitudinally attached with covering an opening 22 of the slot groove 21; and a sheath 4 for covering the circumferences of the slot core 2 and the longitudinally attached tape 3.
