There is disclosed a method and apparatus for forming a metallic sheath about a conductor element comprised of a plurality of optical fibers whose length within the sheath is uniformly greater than that of the encompassing sheath. Such forming is achieved by continuously drawing a metallic strip and a conductor element into a forming apparatus, while heating a portion of the metallic strip for temporarily lengthening it as it is being formed about the conductor element.
