Abstract
Single fiber cables of the composite buffer type are provided which include: (a) a central optical waveguide fiber; (b) a layer of fill compound surrounding the optical fiber; (c) a layer of aramid fiber surrounding the fill compound; and (d) a plastic jacket surrounding the layer of aramid fiber. Multi-fiber cables are also provided which include: (a) a plurality of optical waveguide fibers; (b) a layer of aramid fiber surrounding the optical fibers; (c) fill compound in contact with the inner surface of the layer of aramid fiber and with the optical fibers; and (d) a plastic jacket surround the layer of aramid fiber. Methods for producing cables of these types are disclosed.
