ABSTRACT:
An optical fiber band comprising a pair of thermally sealed thermoplastic films with a plurality of optical fibers in side-by-side relation and following undulate paths embedded therebetween, and a telecommunication signal cable formed by winding a plurality of such bands around an insulated metal rope. The thermoplastic films and the fibers are fed between rollers or cylinders while the fibers are undulated. The films are heated to their softening temperature on at least parts of their facing surfaces prior to reaching the cylinders. The films may each be composite films of different temperature characteristics or may be wider than the final band, heated only at their central portions and then trimmed to the final band size.
