现有的输线结构铜缆地区通信网成为探讨未来光纤地区通信网的出发点。已出现覆盖式通信网和岛形结构,为适应用户的地理分布,提高通信网密度,从而提出了规划、建设和扩建的措施。对于一个技术上有意义、经济上能够负担得起的通信网方案,改单线为二纤维是有意义的。光缆为纤维束结构,用于主线的光缆建议采用10根光纤并以主束扭绞,用于支线的光缆建议采用5根光纤而以分层扭绞。这种地区性的光缆方案揭示了从5根直到2000根光纤束光缆的优点。
The existing transmission line copper network regional communications network to explore the future of fiber optic communications network starting point. Covering communication networks and island structures have emerged. In order to adapt to the geographical distribution of users and increase the density of communication networks, measures for planning, construction and expansion have been put forward. For a technically meaningful and economically affordable communications network, it makes sense to change a single line to two fibers. The optical fiber cable is a fiber bundle structure. For the main cable, 10 optical fibers are recommended and twisted in the main beam. For the optical fiber for the feeder, it is recommended to use 5 fibers to twist the layers. This regional fiber optic cable solution reveals the benefits of up to 5 and up to 2,000 fiber optic cable.
