- Loose Tube:
The GYTA Outdoor Buried Armored Fiber Optic Cable are placed in a high-strength PBT loose tube. The loose tube is filled with water-blocking compound, effectively preventing moisture from entering and protecting the fibers from humid environments.
- Moisture-proof Aluminum Tape:
The loose tube is wrapped with a longitudinally corrugated aluminum tape, which provides moisture resistance and prevents water from entering the cable. It also protects against rodent damage.
- Jacket:
The cable usually made of polyethylene (PE). These provide additional mechanical protection, capable of withstanding high tensile and compressive forces.
- Filling Yarn:
Between the loose tube and the sheath, there is a suitable amount of filling yarn to ensure the roundness and structural stability of the cable.
