摘要
通过对三级光纤联网时前端、光纤和电缆分配部分的指标分配和计算,指出光缆联网级数越少,电缆分配部分的器材越容易选择,造价也越经济。
Through three levels of optical fiber network, front end, the optical fiber and the electric cable assignment partial targets assignment and the computation, the paper pointed out optical cable network progression less, the electric cable assignment partial equipments are easier to choose, the construction cost is also more economic.
