Gyxts optical cable can be buried underground

GYXTS optical cables are suitable for direct burial and underground installation, offering robust mechanical and water-blocking protection.

Suitability for Underground Burial

GYXTS cables are specifically designed for outdoor and underground applications, including direct burial where additional mechanical protection is required. They feature a central loose tube filled with water-blocking compound, surrounded by steel wire or steel tape armor, and finished with a double PE/MDPE sheath for environmental and mechanical protection . This construction ensures the cable can withstand soil pressure, moisture, and potential rodent damage.

Typical Construction

The standard structure of a GYXTS cable (center to outside) includes:

1. Optical fibers housed in a PBT or HDPE central loose tube with water-blocking compound.
2. Central strength member, often steel wire, providing tensile strength.
3. Loose tube stranding and fillers around the strength member for compactness and stability.
4. Water-blocking layer, such as tape or yarn, to prevent longitudinal water ingress.
5. Steel tape armor for mechanical protection against crushing and impact.
6. Inner PE sheath for additional protection.
7. Outer PE or MDPE sheath, UV-resistant, for environmental durability .

Advantages for Direct Burial

• Mechanical protection: Steel wire and tape armor resist crushing, rodent attacks, and soil pressure.
• Water resistance: Water-blocking compounds and sheaths prevent moisture penetration.
• Flexibility: Suitable for duct, aerial, and direct buried installations.
• Durability: Designed for long-term outdoor and underground use, including harsh environments .

Installation Considerations

• Depth of burial and soil conditions should follow local standards to ensure protection.
• In high-risk areas, additional ducting or reinforced armor may be used.
• GYXTS cables are non-self-supporting, so they are not intended for unsupported aerial spans without additional support .

Summary

GYXTS optical cables are fully suitable for underground direct burial, providing high mechanical strength, water-blocking capability, and long-term durability. They are widely used in telecom backbone, distribution networks, and outdoor installations where robust protection is required .
