Real-time Monitoring System For Fiber-optic Network Design And Implementation,

With the rapid development of the optical fiber network,the complexity of network increase the work of management and maintenance become much more heavy in the physical network of optical fiber,the fiber lines appear malfunction frequently,such as broken by somebody,infiltrated by water etc.The malfunction will not interrupt the transmitting signal quickly,but we must konw the place and type of the malfunction,to avoid to lose service and device.So researching Real-time monitor and test the fiber in optical fiber network become a very important problem and has practical value very much.To solve the proplems effectively, this paper put forward a method.In this paper, the developmental status is analysed about domestic technique and market in fiber monitor and test, then the framework is designed in hardware, and devices is choosed reasonably .The system monitor and test the spare optical fiber in optical fiber network in place of the status of the optical cable. 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. The software system include some modules,such as power monitor,device information management,log management, obstacle dispose,user infomation management,configure management,alarm dispose and so on.The system accomplish data collection and analysis,and then dispose the analytical result.The system run with handware well.
