OPTICAL FIBER CABLE

Through the present invention, an increase in the flexural rigidity of an optical fiber cable is suppressed even when an optical fiber ribbon having a large number of cores is used. An optical fiber cable provided with a plurality of optical fiber ribbons having 12 or more cores, a slot rod having a plurality of slot grooves in which a plurality of optical fiber ribbons are accommodated, a tensionmember provided on the inside of the slot rod, and a cable jacketing for covering the outside of the slot rod, wherein, between some or all optical fiber cores in a state in which a plurality of optical fiber cores are arranged in parallel in the optical fiber ribbons, connecting parts in which adjacent optical fiber cores are connected and non-connecting parts in which adjacent optical fiber cores are not connected are provided intermittently in the longitudinal direction, and the relationship between the number x (cores) of optical fiber cores accommodated in the optical fiber cable and theflexural rigidity y (N.mm
