新型室内/外紧套光纤无卤低烟布线光缆

New indoor/outdoor tight buffered fiber LSZH distribution cable

本文介绍了一种新型的无卤低烟 (LSZH)室内 /外用 OFNR型 UL认证的布线光缆 ,这种光缆可容纳 2 4芯以下的直径为 0 .9mm紧套光纤。缓冲层和护套材料的防紫外线性能、阻燃性能、防潮性能都非常好 ,且使光纤在低至 - 4 0°C时性能良好。这些特性使该种光缆非常适合于室内和室外环境应用。这种特殊的光缆设计保持了室内布线光缆的柔韧性、小外径、轻重量等特点 ,同时提供了室外光缆在工作温度范围内具有阻水性和防紫外线等特性。对光缆的特性和设计均进行了讨论 ,并且在 Comm Scope和 UL实验室经过实验进行了验证。也对在印第安纳波利斯动力和光波公司进行的现场安装。

This paper describes a line of Low Smoke Zero Halogen (LSZH) distribution style cables which can accommodate up to twenty four 900 micron Tight Buffer Fibers. The buffer and jacket material is UV stable, flame retardant, resistant to moisture absorption and allows the optical fibers to perform well in temperatures down to -40°C. These attributes make the cable for use in an indoor and outdoor environment. The unique cable design maintains the flexibility, small size and weight of an indoor distribution cable while providing the operating temperature range, water blocking and UV resistance of an outdoor cable construction. The cable performance characteristics and design features are discussed, as are the results from the qualification testing performed at CommScope and UL. Installation, application and results from a field trial performed in conjunction with Indianapolis Power and Light Company will also be presented.
