Management ofCommunication System in Pipeline IndustryBased on OLP Technology

In order to effectively improve the fault self-healing ability of pipeline communication system and reduce the events of communication interruption caused by fiber break or performance degradation of optical line, this paper introduces the basic principle, system composition working mode and technical requirements of OLP technology. The OLP system is firstly introduced into the relay section of long-distance pipeline to build the standby route with the spare optical fiber as material. When the in-service route is broken or the performance of optical fiber is reduced, the OLP system can automatically switch to the standby route within 50 ms to ensure the communication transmission service be uninterrupted, and even no error code alarm. Through engineering test in pipeline industry, the operability of OLP technology applied to the pipeline communication system is verified. Using the real-time monitoring data of optical cable through OLP system, we can analyze the evolution trend of optical cable line quality, precontrol in advance, and improve the level of communication management.
