A high-reliability optical network architecture based on wavelength division multiplexing passive optical network

A highly reliable wavelength division multiplexing passive optical network architecture for the fifth generation (5G) applications is designed by combining a tree topology with a dual-fiber ring. While the tree topology ensures the transmission quality of the network, the dual-fiber ring topology allows one to achieve flexible switching between the nodes, which aims to provide fault protection and network reliability. The signal transmission under the normal and three types of protection modes are analyzed. The performance analysis verifies the feasibility of the proposed architecture.     

风振对OPGW偏振态和通信的影响

光纤复合架空地线(OPGW)中光信号的偏振态会因风振而改变,进而导致系统性能的劣化.为了了解风振对OPGW偏振态的影响,通过实验模拟了在不同摆动情况下OPGW的偏振态变化,并基于所测试的数据分析了偏振态的变化规律和风振对相干光通信的影响,给出了相干光通信系统中所需要补偿算法的计算依据.实验结果表明:2种风振导致的信号光...
