ABSTRACT:
A optical fiber cable wound about an overhead transmission line stretched between supporting poles installed a predetermined distance apart from each other, comprises a tension member, a plurality of plural-core type optical fiber tape-shaped strands arranged on the outside of the tension member, a buffer layer covering outer surface of the arrangement of the plural-core type optical fiber tape-shaped strands, and a sheath covering the outer surface of the buffer layer. The tape-shaped strands each include a plurality of optical fibers arranged side by side, and a covering layer collectively covering the plurality of side by side optical fibers. The particular construction permits the optical fiber cable to house a larger number of optical fibers for a given diameter of the cable while maintaining a high heat resistance and satisfactory mechanical properties.
