城市通信管道光缆集中接续与定点盘留研究

Study on Centralized Connection and Fixed Coil of Optical Cable in Urban Communication Pipelines

为了解决城市通信管道与光缆日益突出的供需矛盾,通过调查目前管道光缆敷设现状和存在问题,分析了光缆接头和盘留的功能及用途,研究了当前光缆网建设规模持续增大后网络维护需求的变化,提出了将光缆接续集中于光缆交接箱、光缆盘留定点于光交前井的方案,并对光缆交接箱及其配套人(手)井建设提出相关要求,进而给出光缆网分层结构的整体优化思路和实施建议。

in order to solve the increasing supply and demand contradiction between urban communication pipeline and optical cable, the status and potential problems in existing pipeline optical cable laying were investigated. The function and application of optical connector and coil were analyzed. The change of the maintenance requirement in the case of progressively increased construction scale of optical cable networks was investigated to propose a scheme that centralized connection in the optical cross connects cabinet and the optical cable coil was placed at the fixed well betbre the cabinet. Corresponding requirements of the optical cross connecting cabinet and its matched supporting construction were presented. In addition, the overall optimization strategy and implementation proposal on the hierarchical structure of optical cable networks were put forward.
