Optical fiber cable

An optical fiber cable in which an optical fiber ribbon formed by arranging a plurality of optical fibers in parallel is mounted in an internal space,

• wherein a core portion of the optical fiber is made of pure silica glass, and an effective cross-sectional area of the core portion at a wavelength of 1550 nm is 110 μm2 or more and 150 μm2 or less,
• wherein the optical fibers constitute an intermittent connection type optical fiber ribbon including 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,
• wherein 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
• wherein 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.
