GYTA53 Outdoor Fiber Optic Direct Burial Cable Layer Loose Tube
GYTS53 Outdoor Fiber Optic Direct Burial Cable Layer Loose Tube
Description
The fibers reside within high modulus plastic tubes, fortified with a water-resistant compound. At the core's
center, a steel wire—possibly coated in polyethylene for high-fiber-count variants—serves as a metallic str-
ength component. These tubes and fillers encompass the strength member, shaping a compact, circular ca-
ble core. To shield against water, the core is filled with a protective compound and encased in a thin PE inner
sheath. After applying PSP (Polyethylene Terephthalate), the cable is completed with a PE outer sheath.
Application
* Customized for outdoor deployment, adept at withstanding diverse environmental conditions.
* Versatile compatibility enables usage in aerial, duct, and direct burial installations.
* Tailored for both long-distance communication and local area network connectivity, providing adaptability for
varied communication requirements in outdoor environments.
Characteristic
1 Strong Mechanical & Temperature Performance: Robust strength and resilience across temperatures for reliable operation.
2 Hydrolysis-Resistant High-Strength Loose Tube: Durable tube safeguards components from hydrolysis damage.
3 Special Tube Filling Compound: Specific compound enhances fiber durability and performance.
4 Crush Resistance & Flexibility: Balances pressure resilience with installation adaptability
5 Watertight Design Measures:
* Steel Wire Central Strength Member
* Complete Filling of Tubes & Cable Core
* APL Moisture Barrier
* PSP for Moisture Resistance
* Water-Blocking Material
