Cable Section Design
Application
- ✰ Frequent lightning area and anti electric field : The subway, tunnel
- ✰ Long-distance communication: Local trunk network & User network
- ✰ Duct and direct buried application
- ✰ Harsh environment
Features
- Good mechanical and temperature performance.
- Special control of exceed length and layer stranding technology.
- Low attenuation and dispersion.
- Single armor and double sheath providing excellent crush resistance, water proof, and avoiding rat bite.
- FRP (non-metallic) Strength Member ensures good anti-electromagnetic interference.
- Stranded loose tube improves the tensile strength.
- Water -blocking material enhances water-blocking & moisture-proof.
- Friction reduction because the tube filling compound ensures a critical protection of the fiber.
- Double sheath design enhancing the crushing performance, good moisture-resistance, ultra violet radiation resistant.

Hot Model Series Direct-buried Fiber Optic Cables
GL' 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 unique for its conductivity and is built for durability, resisting physical and environmental stresses. It's used in telecommunications and network infrastructures, particularly where overhead cabling is not suitable.
