The interruption of the cable line blocking caused by external factors or the optical cable itself affecting the communication service is called a fiber optic cable failure. Blockage of fiber optic cables does not necessarily lead to service interruptions. If the fault causes the service to be interrupted, please follow the fault repair steps to deal with it, which will not affect the service fault. So, what is the cause of fiber optic cable failure?
Optical cable line failure
1. The optical cable is completely broken
If there are reservations on both sides of the site, make a centralized reservation and add connectors to handle it;
There are joints near the breakpoint, and there are sufficient reserves on site. Pull the reserve and process it with the original joint;
There are no reserved and no connectors near the point of failure.
2. The part of the optical cable
rupture of a single tube or rupture of some fibers
The maintenance premise does not affect other active optical fibers. It is recommended to use the skylight connection method to repair the faulty fiber.
What is the reason for the optical cable line?
The causes of optical cable line failures can be roughly divided into four categories: external forces, natural disasters, defects in the optical cable itself, and human factors.
1. Line failure caused by external force
(1) Excavation by external force: deal with construction failures of excavators. Duct cables are opened by manholes near the point of failure to check if the cables are damaged in the manholes and the cables are interrupted in both directions.
(2) Vehicle suspension: When dealing with the vehicle suspension fault, the optical fiber should be tested in both directions at the fault point to confirm the number of blocked optical cables, and then deal with them in a targeted manner.
2. Line failure caused by natural disasters
3. Line failure caused by the fiber optic cable itself
Fiber optic cable application scenarios
(1) Natural fiber breakage: Since the optical fiber is pulled out from glass and plastic fibers, it is relatively fragile. Static fatigue will occur over time and the fiber will gradually age and cause the natural fiber to break. Otherwise the water in the splice box can lead to increased fiber loss and even fiber breakage.
(2) Influence of ambient temperature: If the temperature is too low, the water in the splice box will freeze, the cable jacket will shrink longitudinally, and the micro-bending caused by the pressure on the optical fiber will increase the attenuation or interrupt the optical fiber. If the temperature is too high, it is easy to damage the cable jacket and other protective materials, and affect the performance of the optical fiber.
4. Line failures caused by human factors Work obstacles: human errors caused by technicians' maintenance, installations and other activities. For example, when splicing fibers, the fibers are scratched. The bend radius of the fiber is too small; when cutting the cable, the running fiber is cut by mistake; when splicing, the fiber is not spliced. Fiber breaks.
The above is all the content of fiber optic cable line failures and the reasons for fiber optic cable line failures. I believe you already have a more complete understanding of fiber optic line failures and their causes.
