摘要:

针对智能变电站即插即用就地化线路保护装置通信与其他设备交互时单模和多模即双模光信号在同一光接口传输的要求，设计了一种性能可靠、连接快速的双模(单模+多模)高密度预制光缆。该预制光缆能长期在恶劣气候、环境下使用，光纤连接器具有低连接损耗和高回波损耗的特点。该预制光缆解决了现有预制光缆光传输单一、性能不可靠等问题，提高了光连接的高效性和可靠性。通过对双模预制光缆的测试和验证，表明该预制光缆性能优异，达到了预期的目标。

Abstract:

When outdoor installation line protection devices communicate with other devices in the plug-and-play smart substation, transmitting single-mode and multi-mode optical signals should be at the same optical interface, and then a high-density prefabricated dual-mode (single-mode and multi-mode) optical cable with reliable performance and fast connection is designed. The prefabricated optical cable can be used in harsh weather for a long period. The optical fiber connector has the characteristics of low insertion loss and high return loss. This prefabricated optical cable overcomes the problems of single optical transmission and unreliable performance of existing prefabricated fiber optic cable, and improves the efficiency and reliability of optical connection. The test and verification of the dual-mode prefabricated optical cable show that it has excellent performance and achieves the expected goal. The work is supported by Science and Technology Project of State Grid Hubei Electric Power Company (No. HB1702-0348).
