摘要
光功率是光纤通信的重要指标,光功率的有效管理对于电力系统通信实现状态检修等工作具有重要意义。针对电力长跨距传输系统存在的EDFA等光放大设备,文章提出通过CORBA接口对EDFA进行光功率采集、分析和管理。对EDFA的工作原理、应用方式及特性进行分析,并以10 G骨干网为例,对BA和PA的配置和性能指标进行研究,推导出不同配置情况下光纤衰耗的理论计算公式。依托通信资源管理系统,设计实现了EDFA光功率采集子系统,并根据生产实际进行了数据分析,验证了该系统的实用性。
Optical power is the main index of optical fiber communication, and its effective management has important significance to realize state maintenance and other work for power system communication. Aiming at the EDFA and other optical amplification device existing in the power long-span optical communication system, this paper carries out optical power acquisition, analysis and management of EDFA through CORBA interface. The principle, application methods and characteristics of EDFA are introduced and analyzed. Taking the 10 G backbone network as an example, configuration and performance indexes of BA and PA are studied, and theoretical calculation formula of optical fiber attenuation is derived. Based on the communication resource management system, optical power acquisition subsystem of EDFA was designed and realized and the practicability of the system is verified by the actual production data analysis.
