Hello！Shenzhen Yihong optical fiber and cable Co., Ltd
Custom various fiber and optical cables
With the rapid development of communication technology, optical fiber communication systems have been widely used, from the original long-distance communication lines to the optical fiber to the road, the optical fiber to the building, and the optical fiber to the home. The optical cable barrier is the main factor causing communication interruption. Approximately two-thirds of the statistical obstacles are optical cable obstacles. In order to ensure that the optical fiber line is not blocked, a series of measures have been taken. For example, in the construction of optical cables, corresponding protective measures are taken according to the use environment. Perform daily inspection system, daily maintenance test, etc. in daily maintenance. Due to the widespread use of optical cable lines and long lines, failures will inevitably occur during use. To ensure communication quality, it needs to be repaired immediately. Accurately finding the point of failure is the main step to achieve quick repair.

1 Analysis of the causes of fiber optic cable line failure
1.1 The concept of fiber optic cable line failure
Fiber optic cable line failure refers to the phenomenon that communication services are interrupted due to external factors and damage to the optical fiber itself.
1.2 Causes of fiber optic cable line failure
(1) Excavation. The main cause of fiber optic cable failure is excavation. During the construction of underground projects, the direction of underground communication lines is still unknown, and blind construction poses a direct threat to optical cables.
(2) Technical operation error. Man-made obstacles caused by technicians in the process of equipment maintenance and installation. During the maintenance of the optical cable line, the obstacle easily does not meet the operating specifications. For example, when the optical fiber is connected, the optical fiber is scratched due to the negligence of the technician; or when the optical fiber is used, the bending radius of the optical fiber is too small and does not meet the specifications: when the optical cable is switched, the running optical cable is incorrectly switched, etc.
(3) Other external factors. Fiber optic cable line failures, there are other factors, such as the mouse biting the fiber optic cable, causing the fiber to break; the vehicle is over-elevated or the suspended fiber optic cable of the overhead fiber optic cable sags, causing the vehicle to hang the overhead fiber optic cable; the fire causes the overhead fiber optic cable or the fiber optic cable in the building to explode; natural factors such as Flooding and lightning strikes have caused the fiber optic cable line to be interrupted.
Most of the obstacles in the fiber optic cable line are man-made. The obstacles caused by natural disasters and the quality of the optical cable itself are relatively small. Therefore, we must pay attention to daily maintenance work, strictly abide by the operating procedures, and avoid human factors causing fiber optic cable failure.
