First claim
Opening claim text (preview).
What is claimed is: 1 . An optical fiber cable for air-blown installation, comprising: a plurality of optical fibers or a plurality of optical fiber ribbons; a cable sheath accommodating the plurality of optical fibers or the plurality of optical fiber ribbons; at least one tensile strength member embedded in the cable sheath; and a connection member connected to end portions of the plurality of optical fibers or end portions of the plurality of optical fiber ribbons. 2 . The optical fiber cable according to claim 1 , wherein an outer diameter of the optical fiber cable is 12 mm or more and 15 mm or less. 3 . The optical fiber cable according to claim 1 , wherein the cable sheath is made of a flame-retardant material. 4 . The optical fiber cable according to claim 1 , wherein the optical fiber cable comprises a plurality of optical fiber ribbons, and the plurality of optical fiber ribbons are an intermittent coupling type optical fiber ribbon in which an outer diameter of an optical fiber constituting the optical fiber ribbon is 220 μm or less. 5 . The optical fiber cable according to claim 1 , wherein the optical fiber or an optical fiber in the optical fiber ribbon is a multicore fiber.
