Today, let's take a look at the common obstacles and causes of indoor fiber optic cable lines.
1. All lines are interrupted: R-LOS alarm occurs on the optical board, the possible reasons are that the optical cable is cut, blown or pulled due to external force;
2. The communication quality of individual systems is degraded: an error code alarm occurs, and the possible cause of the line is that the fiber optic cable is damaged during the laying and connection process, causing the line loss to be small; the movable connector is not in place, or there is slight pollution, or other The reason is that the adaptation is good or bad; the performance of the optical fiber is reduced, and its dispersion and loss characteristics are affected by environmental factors; Some special points are under pressure (such as fiber compression in the containment tray), etc.
After determining the line obstacle, use OTDR to test the line to determine the nature and location of the obstacle. When the indoor fiber optic cable line is blocked due to external forces such as natural disasters or external construction, the maintenance personnel shall, according to the location provided by the tester, It is generally easier to find, but if it is not for the above situation, it is not easy to find the obstacle location from the abnormal phenomenon on the route.
At this time, the distance from the obstacle point to the test point measured by the OTDR must be checked with the original test data to find out which section the obstacle point is in. After necessary conversion, the ground distance between them must be accurately measured until Find the exact location of the obstacle point. However, things are often unsatisfactory, and the obstacle point is very different from the position of the measurement and calculation, which is a waste of manpower and material resources, and the impact or loss caused by the obstruction of the optical cable line will be greater.
