Optical cable monitoring device

Abstract

The invention discloses an optical cable monitoring apparatus, belonging to professional field of telecommunication network maintenance. The apparatus comprises an OTDR meter, an optical cable monitoring centre server, a large distributed database, a system client end. The OTDR meter is arranged in the centre equipment room of prefectures via connection of the DCN network; optical channel selecting switching is arranged in the meter to respectively monitor optical fibers with different directions; the optical cable monitoring centre server, system client end use working ways of C/S or B/S; the system client end of the prefectures logins the optical cable monitoring centre server of provincial company via the permission; the optical cable monitoring centre server controls the OTDR meters to process test; the test data are uploaded to the optical cable monitoring centre server to process automated analysis and comparison via the DCN network, automatically generating warming and forming sorts of maintenance statements. This invention effectively enhances the optical cable maintenance efficiency and timely finds hidden troubles in the optical cable, in addition the construction cost is low and the position-setting is simple and convenient and easy for maintaining.

Description

technical field [0001] The invention belongs to the professional field of telecommunication network maintenance. Background technique [0002] As a communication optical cable carrying information, it is often damaged due to various reasons. Once the optical cable is blocked, it will cause huge economic losses and adverse social impacts. Therefore, the requirements for the quality of optical cable maintenance are getting higher and higher. At present, most of the maintenance methods adopt manual inspection and regular OTDR to measure the backup fiber. The maintenance effect of the optical cable is not ideal, and it is difficult to find the hidden dangers on the optical cable in a timely manner. When an obstacle occurs, it takes a long time to determine Whether it is a transmission equipment failure or a cable failure, this maintenance method can no longer meet the needs of the ever-expanding maintenance scale of transmission optical cables. The daily maintenance of optical c...

Problems solved by technology

At present, most of the maintenance methods adopt manual inspection and regular OTDR to measure the backup fiber. The maintenance effect of the optical cable is not ideal, and it is difficult to find the hidden dangers on the optical cable in a timely manner. When an obstacle occurs, it takes a long time to determine Whether it is a transmission equipment failure or a cable failure, this maintenance method can no longer meet the needs of the ever-expanding maintenance scale of transmission optical cables. The daily maintenance of optical cables cannot only adopt the passive management method of "remedial work", and it is necessary to prevent the deterioration of optical fibers. Trends and eliminate hidden dangers in time

With the rapid expansion of the basic network of optical cables in the province, the interruption of optical cables has also increased year by year. In order to ensure communication, it is required to invest more maintenance forces, strengthen maintenance methods, and improve maintenance levels. However, the current optical cable maintenance system mainly It is difficult to meet higher-level maintenance requirements through decentralized and passive manual maintenance methods. The following are the outstanding problems faced in practice:

On the other hand, due to the short construction time of China Mobile's optical cable, there is an essential difference in line maintenance from China Telecom, and a large number of agent maintenance methods are used. Due to the consideration of maintenance costs, it is impossible to achieve the same level as China Telecom. , Complete line departments at all levels from the city to the county, but adopt the method of centralized setting of maintenance units. In a city, there are often only 1-2 maintenance centers (stations), and when a line failure occurs, the maintenance center ( Station) rushing to the fault point, it often takes a lot of travel time, which virtually prolongs the fault duration

Secondly, since most of the current computer rooms are unmanned aerial vehicles, when the transmission system of the primary, secondary and remote computer rooms needs to define line faults and equipment failures, there is often a problem of unmanned cooperation in the computer room, resulting in some faults being unable to be accurately judged and maintenance efficiency. Low; Third, with the further deepening of the reform of the centralized maintenance system, the technical force of on-site maintenance personnel is relatively weak, and the proficiency in instrument operation cannot be guaranteed. fourthly, the current maintenance system mainly judges faults through the maintenance agency, and due to the limitations of various factors, the transmission resource management system cannot be fully shared with the maintenance agency, and the fault judgment mainly relies on paper Data search cannot guarantee the time limit and accuracy of fault location, and it is impossible to automatically dispatch faults; fifth, according to statistics, current line faults account for 30-40% of the entire network faults, and the original maintenan...
