摘　　要：文章针对基于OPGW单芯光纤的输电线路监测系统网络的远距离、高带宽特点和低抗毁性的缺点,提出了一种基于多级级联技术的OPGW光纤网络的组网方法,给出了二级级联模式下系统失效的马尔科夫模型与概率计算公式,与单芯传输模式下的可靠性进行了分析对比,并分析了该模式下系统的抗毁性。采用多级级联技术的网络可靠性优于单芯传输模式,并且可靠性随着级联数的增加而提高。The monitoring system of transmission line based on the optical fiber composite overhead ground wire（OPGW）using single-core fiber optic has such disadvantages as long distance, broad bandwidth and lower invulnerability, so a networking method of OPGW fiber optic network based on the multistage concatenation technology is proposed. The Markov model with invalid system and the probability calculation formula under the two-stage cascade model are given. The reliability of the proposed network is compared with that in single-core transmission mode ＇and its invulnerability is analyzed. The network reliability with multistage concatenation technology is superior to that under single-core transmission mode, and the reliability is improved with the increase of the cascade number.
