Abstract

An optical communication cable is comprised of one or more optical transmission elements loosely positioned within a double-layer synthetic material wrapping. A spun covering composed of elongated (50 to 200 mm) intertwined or unintertwined fibers at least partial coated with an adhesive is positioned about the wrapping. A relatively soft outer casing composed of a synthetic material having a modulus of elasticity smaller than 500 N/mm.sup.2 is bonded onto the spun covering via the adhesive layer. Such cable construction provides improved flexibility and mechanical stability.
