摘要
文章研制一种双纤双向光线路1+1保护装置,利用高速电子开关代替传统光开关,实现1+1保护状态下故障瞬间光路自动切换,并在电力通信网进城主干光缆、地区环境较差的主干光缆光路两端进行了部署应用。试验证明,该系统的倒换时间比传统的光开关型光纤自动切换装置缩短近一半,确保了SDH光传输业务的连续性,从而保障了光传输通信网的稳定可靠运行。
Using high-speed electronic switch to replace traditional optical switch, a 1+1 protection device with double two-way optical fiber line has been developed in this paper, which can realize fault instantaneous optical fiber automatic switching in 1+1 protection state. The device has been deployed at both ends of the electric power communication network backbone optical fiber to city and backbone optical fiber in poor environment. Tests show that it reduces ahnost half of rearrangement delay time than the traditional optical switch type optical fiber automatic switching equipment. The device can ensure the continuity of SDH optical transmission business, and guarantee the stable and reliable operation of the optical transmission network.
