1. An optical fiber cable comprising:
a sheath;
a plurality of tensile strength members embedded in the sheath;
a core that is housed in the sheath and comprises an intermittently-adhered optical fiber ribbon comprising:
optical fibers; and
adhesive portions that intermittently adhere the optical fibers together in a longitudinal direction; and
a wrapping tube that wraps the intermittently-adhered optical fiber ribbon, wherein the wrapping tube comprises:
a wrap portion where a first end portion of the wrapping tube overlaps with a second end portion of the wrapping tube; and
a non-wrap portion positioned between the first end portion and the second end portion,
wherein the optical fiber cable has a compressive strength of 12.8 N/mm2 or greater and 32.4 N/mm2 or less.
