广电节目传输中心多业务光传送网络的建设

Construction of Multi-service Optical Transmission Network in Radio and Television Program Transmission Center

为了适应新时代广播电视卫星信号源安全可靠传输工作要求,满足高清、4K、8K超高清等大容量电视信号传输需要,中央广播电视塔节目传输中心建设了多业务光传送网络(MS-OTN)。本文主要介绍了节目传输中心MS-OTN的组网方案,该方案应用统一线卡技术实现多种速率和类型信号的接入,以及业务级的网络自愈方式。网络建设完成后的验收测试结果符合国家和行业相关标准。

In order to meet the requirements of safe and reliable transmission of radio and television satellite signal source in the new era and meet the needs of high-definition,4K,8K,ultra-high definition and other high-capacity TV signal transmission,the program transmission center of China Central Radio and TV Tower has built a multi-service optical transmission network(MS-OTN).This paper mainly introduces the networking scheme of program transmission center MS-OTN,the application of universal line board technology to realize the access of various rates and types of signals,and the service level network self-healing mode.After the network construction is completed,the network is tested,and the test results meet the relevant national and industrial standards.
