  1. Optical power meter real - time monitor optical power of each optical cable, and control computer gather the value of optical power attenuation circularly, if some values excess the limit, the computer control optical switch to connect another spare optical fiber with otdr card, control the otdr card to test the optical fiber, and then find the malfunction point accurately. the system require software system to run with hardware devices tother. this paper analyze requirement and technical feasibility in software system, ooa and uml are used to analyze software and abstract the class diagram

    通過光功率計對每條光纜中的備用光纖進行實時的監控，測試光功率的衰減值，主控計算機不斷循環的對每個光功率模塊進行數據採集，並記錄每路光信號的光功率衰減值，然後進行分析處理，如發現達到設定的光功率衰減門限值就報警，並控制光開關的切換，將故障光纜中的另一備用光纖與otdr卡連接，通過otdr卡對該光纖進行測試，從而確定故障點。
