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

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.
