这种光缆既可用于电气隔离必不可少的安装在铁路边的电气设备和架空设备的长途通信,也能用于通过危险区域的长途通信和数据传输,还可用作高压电力电缆设施的监控光缆、计算机网络和局部区域网络的连接线。若干根多模或单模光纤绕中央环氧/玻璃复合加强件扭绞在一起,每根光纤都涂以双重缓冲层——“紧密护套”被覆层。扭绞光纤之间的空隙填有阻水复合物,缆芯用聚亚胺酯包覆。为了使缆的强度更高,可用两层Kevlar粗纱和一个塑料外护套增强。英国Pirelli General Plc公司能提供2、4、6、8、10和12根多模或单模
This cable can be used for long-distance communication of electrical and overhead equipment installed on the railroad, which is essential for electrical isolation. It can also be used for long-distance communication and data transmission through hazardous areas. It can also be used as a monitor for high-voltage power cable facilities Cable, computer network and local area network cable. A number of multimode or single-mode fibers are twisted around a central epoxy / glass composite stiffener, each coated with a double cushioning layer - a “tight jacket” coating. The interstices between the twisted optical fibers are filled with a water-blocking compound, and the core is coated with polyurethane. To make the cable stronger, use two layers of Kevlar roving and a plastic outer sheath to reinforce it. Pirelli General Plc UK offers 2, 4, 6, 8, 10 and 12 multimode or single mode
