Leerrohr-Lichtleiterbandkabel unter Verwendung von Lichtleitfaserbündeln, und Verfahren zur Herstellung eines derartigen Kabels

摘要

An optical fibre cable has a plurality of optical fibre ribbon bundles 10 disposed in a tube 16. The ribbon bundles 10 are each bound by distinguishable binders 12. The binders 12 may be distinguished by different colours. The ribbon bundles 10 may be protected from moisture by a gel compound 14. The cable may have a waterproof tape layer 18 formed of a non-woven fabric coated in powder or tension yarns 30 applied to the tube to increase the tensile strength. The cable may have a steel tape layer 20 applied to the waterproof layer 18 or the tension yarn layer 30 and may have a polyethylene sheath 23 covering the steel tape. The cable may include tension members 22 installed outside the steel tape layer 20 and diametrically opposed to one another.
