Basic knowledge of Jiangmen optical cable
Optical cable: Use appropriate materials and cable structures to contain and protect communication optical fibers, so that the optical fibers are protected from mechanical and environmental influence and damage, and can be used in different situations.
Optical cable is made of one or more optical fibers or optical fiber bundles Structure that meets chemical, mechanical and environmental properties.No matter what type of structure, optical cables are basically composed of three parts: cable core, reinforcing element and sheath.
1. Keep the optical fiber in the best position and condition within the cable to ensure stable optical fiber transmission performance.
When the optical cable is subjected to certain external forces such as pulling and lateral pressure, the optical fiber should not be affected by external forces.
2. The cable core cross-section should be as small as possible to reduce costs.
There are optical fibers, sleeves or skeletons and reinforcing elements in the cable core. The cable core also needs to be filled with grease to have reliable moisture-proof performance and prevent moisture from spreading in the cable core.
3. As long as the sheath of the optical cable protects the cabled optical fiber core from external mechanical force and environmental damage, the optical fiber can be adapted to various laying occasions, so the sheath is required to have It has the characteristics of pressure resistance, moisture resistance, good temperature characteristics, light weight, chemical resistance and flame retardancy.
