光缆基础知识
光缆应按芯线领示色排列确定A、B端,敷设时端别朝向应一致, A端朝铁路上行方向,B端朝铁路下行方向。
The cable should be arranged according to the coloring line of the core line to determine the A and B ends. The end orientation should be consistent when laying, the A end faces the railway upward direction and the B end faces the downward direction of the railway.
施工中宜整盘敷设,不得任意切断光缆。
The whole plate should be laid in the construction, and the optical cable should not be cut off at any time.
施工中应保证光缆外护(层)套不得有破损,缆两端头密封性能良好。
In the construction, the outer cover (layer) of the cable should not be damaged, and the sealing performance of the two ends of the cable is good.
敷设过程中最小弯曲半径光缆不应小于护套外径的20倍。
The minimum bending radius of the cable in the laying process should not be less than 20 times the outer diameter of the sheath.
光缆敷设时的张力、扭转力、侧压力应符合工厂规定;牵引力不应大于光缆允许张力的80%,主要牵引力应加在光缆的加强构件上。
The tension, torsional force and lateral pressure of the cable laying shall conform to the factory regulations. The traction force should not exceed 80% of the allowable tension of the optical cable, and the main traction force should be added to the reinforced component of the cable.
施工过程中,应避免光缆受冲击力和重物碾压;不得使光缆变形;当发现变形时,应进行护套密封性检查及光缆衰减性能的检查测试。
During construction, we should avoid the impact of optical cable and the rolling of heavy objects. We must not make cable deformation. When we find deformation, we should carry out the inspection of the sheath seal and the attenuation test of the optical cable.
2. 光缆的敷设方式
The laying mode of 2. optical fiber cable
光缆的敷设一般分为管道,架空和直埋三种。
The laying of optical fiber cable is generally divided into three types: pipeline, overhead and direct burial.
3.新型光缆的布放
The distribution of 3. new optical fiber cable
新型光缆的布放:顶管、吹缆、微管等,
The distribution of new optical cable: pipe jacking, blowing cable, microtubule, etc.
现主要介绍常用两种顶管和吹缆。
Two kinds of pipe jacking and blowing cable are mainly introduced.
