1. Avoid bending: Optical fiber has a certain bending radius requirement, and if over-bending will lead to fiber damage. Therefore, excessive bending of the fiber should be avoided during installation and maintenance.
2. Avoid stretching: stretching of optical fibers can lead to breakage of glass fibers in optical fibers, so excessive stretching of optical fibers should be avoided during installation and maintenance.

3. Avoid twisting: Twisting the fiber can cause the glass fiber to break, so you should avoid twisting the fiber during installation and maintenance.
4. Avoid excessive bending radius: If the bending radius of the fiber is too small, it will cause the glass fiber in the fiber to break. Therefore, the correct bend radius requirement should be followed during installation and maintenance.
5. Avoid squeezing: squeezing of optical fiber can cause the glass fiber in the fiber to break, so you should avoid squeezing of the fiber during installation and maintenance.
6. Avoid contamination: contamination of the fiber can lead to light attenuation and signal loss, so the fiber should be protected from dust, grease, water, fingerprints and other contaminants during installation and maintenance.
7. Use the right tools: You should use the right tools during installation and maintenance to avoid using improper tools that can cause damage to the fiber.
8. Regular inspection: regularly check the tightness of the fiber optic connection and the cleanliness of the connector to find and fix problems in time to prevent fiber damage.
