ABSTRACT:
A composite optical fiber overhead cable having improved long-term strength and loss characteristics. A plurality of optical fibers are accommodated in spiral grooves of the spacer around which conductor strands are wound. The fibers contain flourine in at least one of the core and cladding layers thereof. Each of the optical fibers is provided with a surrounding hermetic coat, and a heat-resistant elastic material is filled between each optical fiber and the bottom of its respective groove to restrain movement of the optical fibers in the grooves in the longitudinal direction.
