Direct Buried Fiber Optic Cable is designed for underground installation without protective conduits. It features multiple protective layers to withstand environmental conditions like humidity, heat, and soil acidity. This cable type is built for durability, resisting physical and environmental stresses, and is used in telecommunications and network infrastructures where overhead cabling is not suitable.
