Abstract

1. An optical fire-resistant communication cable having at least one fibre suitable for optical communication, the optical fibre being surrounded by a sheath of plastics material and the cable containing supporting and/or stress relief reinforcements, characterised in that the fibre sheath (2), the supporting and/or strength reinforcements (3, 4, 5) and the outer cable sheathing (6) consist of a halogenfree, non-crosslinked polyolefin copolymer mixture with flexible properties which does not drip in the event of fire and is filled in a flame-resistant manner, the flame-resistant fillers consisting of 120 - 600 parts of metal hydroxide to 100 parts of polymer.
