Research on the Application of Multimode Optical Fiber Technology in Transmission and Transformation Line Communication Systems
With the development of modern power system,transmission and substation line communication system plays an important role in guaranteeing the stability and reliability of the power system,and fiber optic technology is widely used in power system communication due to its advantages of high bandwidth,low loss,and anti-electromagnetic interference.The article compares and analyzes the performance difference between multi mode fiber and single-mode fiber,and explores the advantages of multi mode fiber in power transmission line communication system.The results show that multimode fiber has high bandwidth performance in short-distance data transmission and is suitable for local area communication in power systems.Although multimode fiber has large attenuation and nonlinear effects in long-distance transmission,dispersion compensation techniques can be used to effectively mitigate these effects.In addition,the application of Optical Time Domain Reflectometer(OTDR)technology in multimode optical fiber can quickly detect and locate faults,and improve the efficiency of system maintenance.
