In fiber optic cabling, signal attenuation is also inevitable. There are two reasons: internal and external: the internal attenuation is related to the optical fiber material, and the external attenuation is related to the construction and installation, so it should be noted that:

1. The first thing that should be done is that the technical personnel who have received strict training should carry out the termination and maintenance of the optical fiber, and operate in accordance with the optical fiber construction specifications.

2. There must be complete design and construction drawings for convenient and reliable construction and future inspections. During construction, be careful not to make the optical cable under heavy pressure or punctured by hard objects; in addition, the traction force should not exceed the maximum laying tension.

3. When the fiber is to be turned, its turning radius should be greater than 20 times the diameter of the fiber itself. When the optical fiber passes through the wall or floor, a protective plastic pipe with a mouth guard should be added, and the pipe should be filled with flame retardant filler. A certain amount of plastic pipes can also be pre-laid in the building.

4. When the optical fiber is used in the backbone network, at least 6-core optical cable should be used in the wiring room of each floor, and 12-core optical cable should be used for advanced applications. This is considered from three aspects: application, backup and expansion.

5. The most important thing for long-distance optical fiber laying is to choose a suitable path. The shortest path is not necessarily the best, but also pay attention to the right to use the land, the possibility of erection or burial, etc.

The above is the reason for the signal attenuation of fiber optic cable introduced to you, I hope it can help you. If you have any other questions, you can contact online customer service.
