There is provided an optical fiber communication cable as described including at least one rigid tension element provided in combination with conventional single tube loose buffer cable and grooved spacer core cable constructions in order to provide greater tensile strength and an enhanced operating temperature range.

Ruggedized optical communication cable

A bonded sheath cable is disclosed of the type having a metallic shield wrapped around a cable core so as to form a longitudinal seam. A jelly-like lubricant overlays the metallic shield seam area and serves to decouple the bond between the metallic shield and an outer plastic jacket. The lubricant allows for relative movement between the longitudinal ends of the metallic shield and the overlying jacket layer without damaging the jacket layer if the bond between the overlapping ends of the metallic shield is broken and the cable twisted during installation or in some other manner.

Bonded sheath cable with lubricant over seam

There is provided a flat optical fiber cable comprised of a plurality of plastic coated optical fibers arranged parallel to one another and enveloped within a fiber-reinforced plastic jacket and possessing enhanced mechanical strength and thermal stability. A plurality of the flat optical fiber cables may be stacked together and surrounded by a plastic sheath which does not require additional strength members in view of the inherent strength of the flat cables contained therein.
