Optical fiber cable

An optical fiber cable comprising:

• a plurality of optical fibers;
• a tensile strength member set that is disposed along the plurality of optical fibers in a longitudinal direction of the optical fiber cable;
• and
• a sheath that covers the plurality of optical fibers from outside and encloses the tensile strength member sets in the sheath,
• wherein at least four tensile strength member sets are embedded in the sheath in a state where the at least four tensile strength member sets are apart from each other in a radial direction of the optical fiber cable,
• the sheath includes an outer layer and an inner layer,
• the inner layer includes a flame-retardant inorganic substance, and
• the outer layer includes a release agent.

An optical fiber cable comprising:

• a plurality of optical fibers;
• at least four tensile strength member sets each being disposed along the plurality of optical fibers in a longitudinal direction of the optical fiber cable;
• and
• a sheath that covers the plurality of optical fibers from outside and encloses the at least four tensile strength member sets in the sheath,
• wherein the at least four tensile strength member sets are embedded in the sheath in a state where the at least four our tensile strength member sets are apart from each other in a radial direction of the optical fiber cable,
• the sheath includes a flame-retardant inorganic substance and a release agent, and
• a distance from one of the at least four tensile strength member sets to a surface layer of the sheath is 0.5 mm or more.
