What are the causes of cable line failure?

1 Optical Cable fault analysis

1.1 Concept of optical cable fault

Optical cable fault refers to the phenomenon that the communication service is interrupted due to external factors or damage to the Optical Fiber.

1.2 Optical Cable Fault Causes

(1) Excavation. The main cause of cable failure is excavation. In the process of underground engineering construction, the direction of underground communication lines is still unknown, and blind construction poses a direct threat to optical cable.

(2) Technical operation error. Artificial obstacles caused by technicians during equipment maintenance and installation. During the maintenance of the cable line, the obstacle is easy to fail to meet the operating specifications. For example, when connecting optical fibers, the optical fibers are scratched due to the negligence of technical personnel; 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 fiber is switched, the running optical fiber is switched incorrectly.

(3) Other external factors. Optical cable line failure, there are other factors, such as mouse bite optical cable, resulting in optical fiber breakage; The vehicle is too high or the hanging optical cable of the overhead optical cable sags, resulting in the vehicle hanging the overhead optical cable; The fire causes the explosion of the overhead cable or the cable in the building; Natural factors such as flooding and lightning strikes have disrupted cable lines.

Most obstacles in fiber optic lines are man-made. The obstacles caused by natural disasters and the quality problems of the cable itself are relatively small. Therefore, we must pay attention to daily maintenance work, strictly abide by the operating procedures, to avoid human factors caused by optical cable failure.
