Abstract
This optical fiber cable comprises an optical unit obtained by creating strands of a plurality of optical fiber tape cores, a tube in which the optical unit is housed, and a cable sheath that covers the outside of an aggregate of a plurality of tubes. The optical fiber tape cores have provided thereto, between some or all of optical fiber cores when a plurality of optical fiber cores are positioned in parallel, and intermittently in the longitudinal direction thereof, connecting parts that connect adjoining optical fiber cores, and non-connecting parts at which adjoining optical fiber cores are not connected. The tube has a Young's modulus lower than the Young's modulus of the cable sheath, and the aggregate is such that the plurality of tubes on the inside of the cable sheath deform elastically with respect to one another, with some thereof being in surface contact with the cable sheath.
