Abstract
A core portion of each of optical fibers of an optical fiber cable is made of pure silica glass, an effective cross-sectional area of the core portion at a wavelength of 1550 nm is 110 μmor more and 150 μmor less. The optical fibers include an intermittent connection portion in which a connection portion to which an adhesive resin is applied and a non-connection portion to which the adhesive resin is not applied are alternately provided between adjacent optical fibers. The optical fiber ribbon has a ratio of a total adhesion length to which the adhesive resin is applied to a total length between all the optical fibers of 40% or more per a unit length of the optical fiber ribbon, and an occupancy ratio of the optical fiber ribbon to a cross-sectional area of the internal space is 30% or more and 40% or less.
