摘要
随着互联网技术全面融入人们的生活,通信技术的重要性越发凸显,而作为通信技术重要载体之一的通信光缆也不断更新换代,承担着传输信号的责任。根据铺设位置的不同,可以将其分为陆地光缆和海底光缆。海底通信光缆的业务承载能力不次于陆地光缆,而为了能够在不同的环境中实现同样的功能,其网络拓扑结构以及主要技术就成为了关键。针对海底通信光缆的常用光纤网络组合方式以及海底光缆信息传输系统的特点,基于同步数字体系(Synchronous Digital Hierarchy,SDH)、波分复用(Wavelength Division Multiplexing,WDM)、SDH+WDM等3种不同的网络设计方案对海底光缆的系统化铺设工作进行了可行性、可靠性以及复杂性分析,旨在为该工作的实际应用提供理论支持。
With the full integration of Internet technology into people's lives,the importance of communication technology has become more and more prominent,and the communication optical cable,one of the important carriers of communication technology,is constantly being updated and is responsible for transmitting signals.Divided into terrestrial optical cable and submarine optical cable.The service carrying capacity of submarine communication optical cable is not inferior to that of terrestrial optical cable.In order to realize the same function in different environments,its network topology and main technology become the key.According to the common optical fiber network combination method of submarine communication cable and the characteristics of submarine optical cable information transmission system,three different networks are based on Synchronous Digital Hierarchy(SDH),Wavelength Division Multiplexing(WDM),SDH+WDM and so on.The design plan analyzes the feasibility,reliability and complexity of the systematic laying of submarine optical cables,aiming to provide theoretical support for the practical application of the work.
