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
