Zusammenfassung:An optical fiber cable comprises a cable core including at least one optical transmission element to transfer light, and a cable jacket surrounding the cable core. The cable jacket is embodied as a multilayered structure having a first sheath layer and at least a second sheath layer being surrounded by the first sheath layer. The material of the first and the second sheath layer is halogen free. The material of the first sheath layer and the material of the second sheath layer have a different flame retardant additive providing different flame retardant mechanisms.
