Technical Development and Application Scenarios of 50G-PON
With the popularization and development of technology,the optical access network is continuously developing and evolving in multiple dimensions,such as higher bandwidth、full service bearer and stronger intelligence.Since 2020,three major domestic telecom operators have launched"three gigabit"services,namely,gigabit 5G,gigabit broadband and gigabit Wi-Fi,to provide users with a full scene,immersive gigabit experience.Based on the current status of EPON/GPON/10G PON network and the demand for network access of new business scenari-os such as high-definition video,industrial Internet and industry digitalization in the future,this paper introduces the research prospects,development needs and key technologies of 50G PON optical network.
