无源波分设备建设策略探讨

Discussion on construction strategy of passive wavelength division equipment

随着城市管道资源紧张,光缆敷设场景也在逐步受限。5G前期各运营商争抢建设进度、工期紧,光缆敷设周期较长、资金投入大。光缆敷设最后一公里存在入户难、入户贵的问题。介绍无源波分系统网络架构,分析了无源波分建设需求及使用原则,并通过无源波分建设场景,提出无源波分建设模式、安装策略等来解决这些问题。

With the shortage of urban pipeline resources, optical cable laying scenarios are gradually limited. In the early stage of 5G,operators are competing for construction schedule, construction period is tight, cable laying cycle is long, and capital investment is large. The last kilometer of cable laying is difficult and expensive. This paper introduces the network architecture of passive wave division system,analyzes the construction requirements and application principles of passive wave division, and puts forward passive wave division construction mode and installation strategy to solve these problems through passive wave division construction scenarios.
