Multi Mode HDPE Direct Burial Fiber Optic Cable 1000~4000m/Reel
Description of Burial Fiber Optic Cable
Buried cable is a kind of communications cable which is especially designed to be buried under the ground without any kind of extra covering, sheathing, or piping to protect it. This cable is built to specific tolerances to heat, moisture, conductivity, and soil acidity.
Feature of Burial Fiber Optic Cable
1. Low dispersion and attenuation
2. Proper design, precise control for fiber excess length and distinct stranding process render the cable
3. excellent mechanical and environmental properties
4. Compact structure and lightness, flexible and good bend-resistant performance
5. With small cable diameter, light cable weight, self-supporting
6. Operating Temperature : -40 ~ +60 C
