Abstract
Provided is an optical fiber cable whereby macrobend loss can be suppressed even when ribbons are mounted at high density in grooves. An optical fiber cable provided with optical units in which ribbons each having a plurality of optical fiber cores arranged in parallel are collected, a slot rod having a plurality of grooves for accommodating optical units, a tension member on which tension is applied, and a cable jacket for covering the outside of the slot rod. Each of the optical units is accommodated in the corresponding groove in a stranded state, and the occupancy of the optical units calculated from the cross-sectional area of the optical units with respect to the cross-sectional area of the groove is 25% to 65%.
