智能变电站改变了传统变电站的建设模式，其全站组网的构架使得通信光缆成为变电站的主要通信介质。现有户外光缆联接手段存在诸多弊端，已不能满足智能变电站的发展需求。提出了一种基于预制光缆的户外组网解决方案，并将其成功应用到实际工程中，有效提高了变电站网络通信的安全性、可靠性和稳定性。该解决方案具有结构简单、施工方便、安全可靠、使用寿命长等优点，增加少量投资就可以大幅度缩短施工周期、提高智能变电站的抗故障能力。

The smart substation changes the construction mode of traditional substation, in which the optical fiber cable becomes the main medium for communication because of its network. The existing connecting way of outdoor optical fiber cable has many disadvantages and can not satisfy the need of smart substation development. A solution based on prefab optical fiber cable for the outdoor network is proposed, which had been successfully applied to practical project and could efficiently improve the security, reliability and stability of network communication in substation. This solution has many advantages, such as simple structure, convenient construction, safety, durable use. It can greatly shorten the construction period and improve the fault resistance ability of smart substation, with increasing a little investment.
