1. Optical cable is too long
2. Excessive bending
3. The optical cable is compressed or broken, and the optical fiber is subjected to uneven tension. For example, when the optical fiber is subjected to pressure or temperature changes, the shaft of the optical fiber bends slightly irregularly or even breaks. Loss of energy.
4. Bad splicing of the optical cable
5. Core diameter mismatch
6. Filler diameter mismatch
7. Connector contamination, fiber connector contamination and moisture in the pigtail are one of the most important reasons for optical cable communication failures.
8. Poor joint polishing
Poorly polished joints. Poor connector contact primarily occurs at the end of the optical path, such as optical distribution boxes and optical switches. It may be due to operator negligence, equipment quality problems or aging of connectors, etc., resulting in loose fiber optic connectors, causing reflection loss and leakage attenuation of optical signals.
