Optical fiber cable with high friction buffer tube contact

摘要

An optical communication cable is provided. The cable includes a cable sheath including an inner surface defining a channel within the cable sheath and a plurality of buffer tubes located in the channel of the cable sheath. Each buffer tube including an outer surface, an inner surface and a channel defined by the inner surface of the buffer tube. The cable includes a plurality of optical fibers located within the channel of each buffer tube. The cable includes a friction structure located on at least one of the inner surface of the sheath and the outer surfaces of each of the plurality of buffer tubes and the friction created by the friction structure provides resistance to cable deformation under loading, such as crush loading. A cable also including an elongate rod located in the channel of the cable sheath is additionally provided. The friction structure may be located on the outer surface of the elongate rod.
