ARMOURED CABLES FOR RAILWAY DUCTSTFvST Sheath - Micromodule structure - K209B Type DESCRIPTION AND APPLICATION Micromodule structure fibre-optic cables with a double LSZH thermoplastic sheath, fibreglass yarns and armoured with a steel tape for mechanical and rodent protection. This cable can be installed in underground ducts or directly buried. For use in medium or long distance networks. 1. Micromodules: fibres are grouped into a jelly-filled micro-structure of 6 or 12 fibres and a maximum diameter of 1.4 mm. 2. Core: The micro-modules are grouped inside without any central reinforcing element. 3. Water-blocking yarns and/or tapes. 4. LSZH thermoplastic inner sheath. 6. Corrugated copolymer-coated steel tape longitudinally applied with overlap. 7. LSZH thermoplastic outer sheath. UV protected. Markings: CA BLESCOM / Year / Number of fibres / Type of fibre / Type of sheath / Length markings Other sheath markings available upon request OPTICAL FIBRE CHARACTERISTICS Optical fibres are according to ITU-T G.652D recommendations and EN 60793-2 - Class B 50 B 1.
