Optical Cables for Railway Transportation
13Pages

With the increase of operation length, the corresponding demands for communication devices of rail transit keep increasing. Optical cables are widely used in rail transit for their remarkable safety, electromagnetic compatibility, reliability, multi-interfaces and extendibility. Meanwhile, the safety of rail transit has become more and more important. For the optical cables, the most serious accident is fire. Once the cable is damaged by fire, the communication might be interrupted, making it impossible to monitor the signals and control the key devices, thus making it difficult for the...

Merits of YOFC's Optical Cables for Rail Transport: • A full range of optical cables and all-round measures are provided, including cabling in limited space and emergency treatment, etc. • Easy for construction and maintenance, with low later-stage costs • Optical cables of different fire-resistance levels are available for different applications on request • Special fire-resistant structure and materials are used, which are environment friendly • Comply with relevant standards including IEC60754-1&2, IEC 60332-1&3, IEC 60331 and IEC61034, etc. Yangtze Optical Fibre and Cable Joint Stock...

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member to form a cable core. The core is armored with a layer of fire resistance tape and glass fibre yarns. Then, a LSZH outer sheath is extruded. Features • Accurate process control ensuring good mechanical and temperature performances • The material of loose tubes with good hydrolysis resistance and relatively high strength • Small size and light weight, easy for installation • Fire-resistant...
