Title
(EN) Optical fiber cable
Abstract
(EN)

An optical fiber cable comprises optical units having a plurality of optical fiber ribbons, a slot rod having a plurality of slot grooves in which the optical units are accommodated, and a cable sheath configured to cover an outer side of the slot rod, each of the optical fiber ribbons is intermittently provided with coupling portions, at which adjacent optical fibers are coupled therebetween, and non-coupling portions, at which adjacent optical fibers are not coupled therebetween, in a longitudinal direction between a part or all of the optical fibers in a state where the plurality of optical fibers is arranged in parallel, and an outer diameter of the optical fiber cable is 35 mm or less and a number of the optical fibers in the optical unit accommodated in one slot groove is 100 or more.
