摘要

随着电网对通信带宽的需求逐步增长，光传送网（optical transport network，OTN）在电力通信中的应用日益广泛、深入，在应用过程中出现了一系列亟待解决的问题：OTN的长距离传输问题、雷电导致OPGW承载的偏振复用OTN系统闪断问题、业务需求的发展趋势与OTN设备功能组合的匹配问题。简要梳理、介绍了这3个问题的背景、原理；在实际的OTN系统建设工程中使用前后向拉曼放大器及后向遥泵放大器，并将其光信号沿着光纤远传的功率分布进行了理论计算并以工程实测数据验证，定量证明了前后向拉曼放大器及后向遥泵放大器对 OTN 系统的单跨段传输距离的增益；对自然雷电导致光信号 SOP 旋转的速度进行了理论估算并在实际系统中进行测量，提出了对 OTN 设备跟踪 SOP 能力的测试方法并进行了实际测试；提出了应用分组光传送网（pakect optical transport network，POTN）技术提升OTN带宽调度灵活性的思路。

Abstract

With the gradual increase in the demand for communication bandwidth in the electric power grid

the application of optical transport network (OTN) in electric power communication has become increasingly extensive and in-depth.A series of problems to be solved have been found in the application process.The long-haul transmission problem

the interruption problem of OTN with polarization multiplexing carried by OPGW which is caused by lightning strikes

the problem of mismatch between trend of service requirement development and functions combination of OTN equipment.The background and principles of the above three issues were briefly sorted out and introduced.The forward and backward Raman amplifiers and remote optical pumping amplifiers were applied in the practical OTN system construction project.Theoretical calculations of the optical power distribution along the fiber were carried out and verified by field measured data

which quantitatively proved the gain of amplifiers mentioned above on the single-span transmission distance of OTN systems.The speed of the rotation of SOP caused by natural lightning strikes was theoretically estimated and measured in the practical OTN system.A test method for the SOP tracking ability of the OTN systems was proposed and carried out.An idea of applying the pakect optical transport network (POTN) to imporve the flexibility of OTN bandwidth administration was proposed.
