光缆线路在山区施工中由于受地形地貌的限制 ,往往很难达到线路设计标准要求 ,这就要求施工时根据地形实际情况合理地安排线路走向。一般从便于施工、线路架设难易程度等方面考虑线路的走向。( 1)以方便施工、方便线路架设为前提 ,同时兼顾以后维修维护方便等问题 ,综合安排光? Due to the restriction of topography and geomorphology of optical fiber cable in mountainous area construction, it is often difficult to meet the requirements of the standard for circuit design. This requires rational arrangement of the line direction according to the actual situation of the terrain during construction. Generally from the ease of construction, easy to set up the line to consider the line direction. (1) To facilitate the construction, to facilitate the erection of the line as a prerequisite, taking into account future maintenance and other issues of convenience, the overall arrangement of light?
