Definition of Direct Buried Fiber Optic Cable
Directly buried fiber optic cables are buried directly underground without protection. Direct buried fiber optic cable does not have any cover or jacket.
Most direct burial fiber optic cables are unique in that they can withstand humidity, heat, and soil acidity in the soil. And the direct burial fiber cable also has the certain conductivity.
Description of single mode fiber direct burial
Direct burial cables have no protective covers and they are buried directly underground. They may be exposed to harsh environmental conditions such as changes in temperature and humidity in the soil. Therefore, the different environments faced by direct burial cables determine the level of protection required.
The Nestor Cables range includes a wide range of rugged, straight-buried cables. These include classic cables with central tubes, new innovative fiber optic cables with stranded loose tube construction, and new innovative fiber optic cables with flexible construction. This series of cables is suitable for difficult installation conditions.
Whether it's a solid armored fiber optic cable buried directly in the ground, or a conduit that can pass anything, a direct-buried fiber optic cable is an ideal mounting material. Corrugated steel strips provide a protective barrier between the cable and its surrounding components thanks to its excellent water resistance. Armored direct-burial fiber optic cables operate over the -40°C to 85°C temperature range, so they are well protected against harsh temperatures.
