The Research of Overmodulation AMCC for Optical Access Network
摘要
Abstract
[Objective]The Auxiliary Management and Control Channel(AMCC)based on overmodulation technology is inde-pendent of the data service and has the advantage of ultra-low latency jitter,aligning with the development trend of access net-works,which feature large bandwidth,low latency,and intelligence.This article aims to explore the principles,implementation methods,and technical verification of overmodulation AMCC technology in optical access networks,and provides an in-depth analysis of its novel applications in access networks.This serves as a reference for further research and development,as well as engineering applications of this technology in access networks.[Methods]Through a literature review and analysis of experimen-tal data,the article systematically elaborates on the technical principles of overmodulation AMCC.The research focuses on ex-ploring low-cost implementation pathways for it in optical access networks,including technologies such as direct modulation lasers and split detectors.The paper also analyzes the application of overmodulation AMCC technology in different optical network sys-tems and its impact on network performance.It further discusses the application methods of related technologies in access network systems for multi-channel monitoring,reflection,optical power estimation,and the avoidance of Time Division Multiplexing(TDM)Passive Optical Networks(PON)silent windows.[Results]The study shows that overmodulation AMCC technology can effectively support multi-channel monitoring and management in access networks,distinguishing it from traditional methods.It is particularly applicable in The 5th Generation Mobile Communication Technology(5G)front-haul transmission,optical line reflection monitoring,and low-latency TDM PON systems.This technology supports high-speed network transmission while en-abling the perception and management of optical layer channels,demonstrating significant technical potential in addressing TDM PON silent window issues.[Conclusion]The overmodulation AMCC technology can achieve low-cost,multidimensional multi-plexing of high-speed data and low-speed signals in access networks to a certain extent.It has broad application prospects in opti-cal access networks,enhancing the intelligent management level of networks while fulfilling requirements for large bandwidth and low-latency communication.Additionally,it facilitates perception at the optical layer.Implementing this technology can improve network efficiency and stability,meeting the developmental needs of The 5th Generation Fixed Network-Advanced(F5G-A)and The 6th Generation Fixed Network(F6G)in future.Further research on its application in PON structures,more modulation formats,and additional application scenarios could optimize its performance and adaptability,promoting its vigorous development.关键词
