An optical fiber cable suitable installation using an air-blown method is disclosed. The optical fiber cable has a center tensile member located at a center of the optical fiber cable to provide tension-resistant force, at least three loose tubes each of which includes at least one optical signal transmitting medium, and located to surround a peripheral portion of the center tensile member, a binder surrounding the loose tubes to maintain an alignment pattern of the loose tubes, and a sheath located at an outermost portion of the optical fiber cable. The optical fiber cable has a polygonal sectional shape having smooth edges.
