Abstract
An optical fiber cable includes a plurality of optical fibers and at least one tubular jacketing element surrounding the plurality of optical fibers. The jacketing element has a jacketing material containing at least a first ingredient being a thermoplastic polymer, a second ingredient being an intumescent material capable of releasing gas, under the influence of heat, for generating a foam, and a third ingredient being a stiffening agent capable of decomposing, under the influence of heat, with formation of a glass and/or of a ceramic material for stiffening the foam.
