摘要
鉴于城市管道、杆塔资源匮乏等原因,采用10 kV光纤复合架空绝缘电缆是提高10 kV通信接入网光纤使用率的有效解决方案。由于易受雷击断股、城市改造、外力破坏等因素影响,目前在10 kV通信接入网对光纤复合电缆的使用非常谨慎。文章研制了一种可对10 kV光纤复合架空绝缘电缆的断股进行永久性快速修复的接续盒。研制的10 kV光纤复合架空绝缘电缆采用G.657.A2弯曲不敏感光纤,解决了因接续盒外径小、余留光纤弯曲损耗大的不利因素。经检测产品性能满足各相关标准要求。
Due to the inadequacy of urban cable duct and cable pole, the adoption of the 10 kV optical fiber composite overhead insulated cables is the most effective solution for increasing the utilization of optical fiber of 10 kV conununication terminal access network,. However, it is cautious to use optical fiber composite cables in the 10 kV communication terminal access network because of the influence of lightning strike, urban renovation, accidental damage. The paper develops a type of connection-box that can permanently fix the broken-cables of 10 kV optical fiber composite overhead insulated cables. Moreover, this paper solves the adverse factors, such as th small outer diameter of connection-box and the large bend loss of remained fibers by using G.657. A2 bend insensitive fibers to produce the 10 kV optical fiber composite overhead insulated cable. According to the testing results, the performance of the products satisfies the related requirements.
