摘　　要：现有国际海底光缆和陆地光缆传输系统是依据各自规范独立设计的,两类系统在海底光缆登陆站采用背靠背方式连接。针对现有方式存在投资和运营成本相对较高的问题,阐述了海底光缆、陆地光缆光传输系统联合组网的发展需求,在分析海底光缆系统和陆地光缆系统设计规范的基础上,建议采用广义信噪比指标衡量总体传输系统性能。最后,结合实例对海底光缆、陆地光缆光传输系统联合设计进行了研究,并给出了系统应用建议。The existing international submarine cable system and terrestrial cable transmission system are designed independently according to their respective specifications,the two types of systems are connected through back-to-back method in the submarine cable landing station.In view of problems of relatively high investment and operating costs problems in existing methods,this paper elaborates the developing requirements of the joint network design of the submarine cable and terrestrial cable optical transmission system.Based on the analysis of the design specifications of submarine cable system and terrestrial cable system,it is suggested to use the generalized signal-to-noise ratio index to measure the overall transmission system performance.Finally,the joint design of the submarine cable and terrestrial cable optical transmission system is studied based on examples,deploying suggestions are given as well.
