Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber route calibration device based on optical fiber vibration sensing technology. Background Art

[0002] Optical fiber communication has the advantages of large capacity, high quality of information transmission, long transmission distance, stable performance, strong anti-electromagnetic interference and corrosion resistance, and has been vigorously developed in recent years. With the expansion of the scale of optical fiber networks and the increase in network complexity, a higher level of monitoring and management system is required to timely and accurately monitor the possible blocking positions of each optical cable segment in the entire network, so as to organize personnel for emergency repair in a timely and effective manner, greatly reduce and compress the duration of faults, and change passive maintenance to active maintenance.

[0003] The operation and maintenance of the optical cable network involves work at multiple levels. In terms of business, when the optical cable fails or even breaks, it is necessary to ensure that the business can continue without interruption. In terms of maintenance, it is hoped that regular inspections and monitoring can be carried out to provide early warning of faults, and accurate analysis and positioning of faults can be carried out when they occur to ensure rapid repairs. In addition, it is also necessary to effectively manage basic data such as optical cable facilities.

[0004] To ensure the normal operation of optical cable communications, operators need to arrange personnel to conduct daily line inspections with reference to routing drawings, so that they can handle safety issues in a timely manner when construction is found near the optical cable. However, due to factors such as insufficient line inspection personnel, many constructions are not discovered by the operation and maintenance personnel during line inspections, and many of them are barbaric constructions without prior reporting. When the optical cable is cut afterwards, it cannot be reported in time. For these faults, the operation and maintenance personnel can only find the fault point and repair it according to the length of the optical cable fault skin and the routing layout diagram.

[0005] However, there are often large differences between the existing optical cable laying drawings and the actual optical cable directions, which makes line operation and maintenance difficult. With the continuous iteration of optical fiber communication technology, after many years of addition, reconstruction and adjustment, the optical cable resources in the pipeline are in chaos, and it is impossible to accurately identify effective communication optical cables, making maintenance and repair difficult. When an optical cable fails, it is impossible to quickly find the specific geographical location of the optical cable fault point based on the length of the optical cable skin, which makes the line repair efficiency very low.
