光保护技术在新疆电力通信系统中的应用
|
摘要
针对新疆电力通信系统中存在的问题,介绍了OLP(光线路保护)系统的工作原理,重点研究了OLP系统在巴州-库车段超长距线路实际应用中的可靠性保障措施,包括光功率补偿、色散补偿、OSNR(光信噪比)补偿以及切换时间等,并给出了具体实现的原理和方法。实际测试结果表明,OLP设备能在毫秒级时间内完成新疆电力通信系统主干线路的路由切换功能,保障业务通信正常,大大降低了业务故障率。
In connection with the problems existing in Xinjiang electric power communication systems,this paper introduces the working principle of Optical Line Protection(OLP)system,focusing on the measures for ensuring the reliability of the OLP system in the ultra-long lines of the Bazhou-kuche section in practical applications,including optical power compensation,chromatic dispersion compensation,OSNR compensation and switch time and gives the principle and methods for its concrete implementation.The actual test results show that the above-mentioned OLP devices can complete the optical router switching of the backbone trunk lines of the Xinjiang electric power communication system in milliseconds,ensuring normal service communication and greatly reducing the service failure rate.
