摘　　要：随着互联网宽带的应用和升级,中国移动、中国联通和中国电信等运营商已经开始为用户提供千兆全光网络宽带业务,实现了4K、8K等高清晰视频业务的传输,严重侵蚀了中国广电的市场业务,尤其是直播电视业务。因此,广电网络为了满足用户高清晰视频发展需求,也积极地升级和改造传输网络,利用吉比特无源光网络(Gigabit Passive Optical Network,GPON)技术实现全光网络传输直播业务。对此,详细分析GPON技术在广电传输网络的应用,重点分析GPON技术在高清晰电视直播业务中的应用,以期能够以点带面,实现广电传输网络的升级,进一步实现高速数据传输。With the application and upgrading of Internet broadband,operators such as China Mobile,China Unicom and China telecom have begun to provide users with Gigabit all-optical network broadband services,realizing the transmission of 4K,8K and other highdefinition video services,which has seriously eroded the market business of China radio and television companies,especially the live TV business.Therefore,in order to meet the development needs of users’high-definition video,the radio and television network also actively upgrades and transforms the transmission network,and uses Gigabit Passive Optical Network(GPON)technology to realize the all-optical network transmission live broadcast service.This paper analyzes the application of GPON technology in the radio and television transmission network in detail,and focuses on the application of GPON technology in the high-definition TV live broadcast service,so as to realize the upgrading of the radio and television transmission network from point to area and further realize the highspeed data transmission.
