Gyxts optical cable can be buried underground

GYXTS optical cable is suitable for direct burial underground, with proper protection and installation practices.

Suitability for Underground Use

GYXTS optical cables are designed for outdoor direct burial and can also be installed aerially . They feature a jelly-filled loose tube containing optical fibers, surrounded by a layer of galvanized steel wires and a black polyethylene (PE) sheath, which provides mechanical protection, moisture resistance, and rodent protection . This construction makes them suitable for long-haul communication, subscriber networks, and local area networks in underground environments.

Installation Considerations

When burying GYXTS cables underground, several factors should be considered:

• Trench Depth: Typical burial depth ranges from 18–36 inches, depending on soil type, local regulations, and traffic load. Urban areas may require shallower burial (12–24 inches), while rural or high-traffic zones may need deeper burial (24–48 inches) for added protection .
• Mechanical Protection: Although GYXTS cables have steel wire armor, additional protection such as conduits or warning tapes may be used to prevent accidental damage during excavation .
• Bend Radius and Pulling Tension: During installation, maintain the cable's minimum bend radius and avoid exceeding the maximum pulling tension to prevent fiber damage .
• Environmental Conditions: GYXTS cables are rated for operation in temperatures from -40℃ to +70℃, making them suitable for a wide range of underground environments .

Comparison with Other Buried Cables

• GYTA53: Stronger in compressive resistance, tensile strength, rodent proofing, and moisture protection, often preferred for high-risk environments .
• GYTY53: Single-armored, suitable for power plants and high-voltage areas, but less robust than GYTA53 .
• GYXTW53: Thinner and less suitable for deep direct burial .

Best Practices

• Conduct a site survey to assess soil conditions, traffic load, and potential hazards.
• Use direct burial in stable, low-risk areas, or conduit installation in urban or high-traffic zones for extra protection .
• Install marker tapes above the cable to aid future maintenance and prevent accidental cuts .
• Ensure proper splicing, termination, and testing after installation to maintain long-term network reliability .

In summary, GYXTS optical cable can be safely buried underground if installed according to recommended depth, mechanical protection, and environmental guidelines. For higher-risk or high-traffic areas, consider using more robust alternatives like GYTA53 or installing the cable within a protective conduit.
