The Application Of Optical Fiber Monitor & Test System In The Maintenance Of Optical Fiber Cable

Along with the rapid growth in demand for network bandwidth, fiber-optic communications technology has been more widely used in the telecommunications field. Accordingly, the fault of fiber-optic communication has risen as well, so it causes the effective monitor of the fiber failure becoming more and more urgent. Obviously, the problems cannot be completely resolved only by traditional manual inspections. Fortunately, the integration of fiber-optic communication technology, Internet technology, and software engineering technology offer us a much better resolution.At present, some foreign fiber equipment manufactures already provide some mature monitoring system solutions. But a number of problems still exist to totally import and implement these solutions. Firstly, these systems are often expensive and very high import costs. Moreover, there is poor compatibility between the systems of various manufacturers, resulting in a very narrow range of choices for upgrading. Finally, some software systems services cannot be customized, so they cause some conflict issues between the existing systems and new ones, which make a low efficiency. The researches done in this paper are working on how to deploy a fiber-optic monitor system via studying some successful foreign cases. According to the maintenance demand of the fiber cable by Shanghai Telecom, the monitoring system should cover 14 first-class cables in the area, support a flexible fiber backup and online monitor resolution fiber and show up the visual position and info of failure on an e-map with WebGis format. When the fault occurs, the system can let us know the problem immediately, figure out where it is quickly and accurately, shorten the time for the cable repair, and restore the communication business, which may lower the losses to the minimum.In this paper, it starts on comparing several popular fiber monitor systems, analyzing a various performance indicators of optical components, combining the fiber cable status in Shanghai Telecom area, researching the hardware design of fiber cable backup system, fiber routing monitor system and the optical optical devices distribution system. Then it works on the design of GIS database, researches the software design of data tables, attribute tables, warning reception daemons, warning positioning systems showing WebGIS module. Finally, it gives objective evaluations of the working status of the system and describes the lack and prospects.
