Abstract: An optical fiber cable includes an optical fiber core wire; a pair of tension members extending parallel to each other in an extension direction of the optical fiber core wire, sandwiching the optical fiber core wire; and a rectangular jacket covering the optical fiber core wire and the pair of tension members, and in a cross-section orthogonal to the extension direction, having a major axis in a facing direction of the tension members and a minor axis in a direction orthogonal to the facing direction, wherein each of the tension members is glass fiber reinforced plastic having a diameter in a range of 0.7 mm or more and 1 mm or less, and the jacket has a friction coefficient of 0.3 or less, the major axis of 4 mm or less, and the minor axis of 2.8 mm or less.

Abstract: An optical fiber cable includes: a slotted core which houses and holds an optical fiber in a rectilinear slotted groove disposed along a longitudinal direction of the cable; a cylindrical sheath covering the entire slotted core; a rectilinear hanger line integrally provided continuously to the sheath; and a rectilinear tension member mounted in the slotted core. The tension member is located in a region having an angle about the cable center line within a predetermined value with respect to a plane including a center line of the suspension wire and the cable center line.
