OPTICAL FIBER CABLE WOUND ABOUT OVERHEAD POWER TRANSMISSION LINE

摘要

Disclosed is an optical fiber cable wound about an overhead transmission line stretched between supporting poles installed a predetermined distance apart from each other. The optical fiber cable comprises a tension member, a plurality of plural-core type optical fiber tape strands arranged on the outside of the tension member, a buffer layer positioned to cover the outer surface of the arrangement of the plural-core type optical fiber tape strands, and a sheath positioned to cover the outer surface of the buffer layer. The particular construction permits the optical fiber cable to house a larger number of optical fibers while maintaining a high heat resistance and satisfactory mechanical properties.
