基于WDM的高精度光纤远程时间传递技术
High Precision Optical Fiber Remote Time Transfer Technology Based on WDM
摘要
Abstract
The real-time and synchronization of the power optical fiber communication network directly affect the efficiency of the entire power grid communication network.To address issues such as line noise and delays in traditional time transmission techniques,this paper constructs an optical fiber timing system based on single-fiber bidirectional wavelength division multiple-xing(WDM)technology.Using master-slave time synchronization,precision measurement and control techniques to construct a noise transfer model,the end-to-end delay of optical fiber is locked by servo device,and the node clock time base aging and optical fiber line drift are monitored.Both the model and field verification indicate that a WDM-based optical fiber timing net-work can achieve remote and high precision time transfer.关键词
