Self-supporting Bow-type Drop fiber optic cable

The optical fiber unit is positioned in the center, Two parallel Fibre Reinforced plastics(FRP) are placed at the two sides. A steel wire as the additional strength member is also applied. then cable completed with a black or color LSZH material jacket.

Characteristics

● Special low-bend sensitivity fiber provides high bandwidth and excellent communication transmission properties.

● Two parallel FRP strength members ensure good performance of crush resistance to protect the fiber.

● Simple structure, lightweight, and high practicability.

● Novel flute design, easily strip, and splice, simplify the installation and maintenance.

● Low smoke, zero halogen, and flame retardant sheath.

● Single steel wire as the additional strength member ensures good performance of tensile strength.

Question? Check out our answer.

1. What is the difference between self-supporting butterfly cables and traditional optical cables?

A: Self-supporting butterfly cables use steel wire as a tensioning element, eliminating the need for additional flyers or support structures and allowing for direct overhead installation. The flat main cable has internal reinforcements (such as steel wire and FRP/KFRP) that independently support its own weight and external loads, significantly reducing installation cost and complexity.
2. What is the maximum span of an self-supporting fiber drop cable? How should I select a cable based on this span?

A: The maximum span is designed based on meteorological conditions (wind speed, icing).
For example, under moderate load conditions, it can reach 500 feet (approximately 152 meters), while under heavy icing conditions, it can reach 400 feet (approximately 122 meters).
Key to FTTH drop fiber cable selection: The cable must be customized based on the maximum span (not the average span) to avoid fiber breakage due to overloading. For example, an 80-meter span requires a dedicated cable; a 50-meter span cable cannot be used as a substitute.
3. Are specialized tools required when installing a self-supporting bow-type drop cable? What precautions should be taken?

A: Specialized tools (such as a tension controller) are required. Manual pulling can easily damage the sheath and fiber core. Key requirements include:
Long-term tension ≤ 300N, short-term tension ≤ 600N;
Working bend radius ≥ 30mm (static) 137.
4. Can the outdoor fiber optic drop cable withstand extreme temperatures?

A: Yes, the operating temperature range is -40°C to +70°C, and the storage temperature is also -40°C to 70°C. It can withstand harsh climates, including extreme cold and high temperatures.
5. What are the fiber types and attenuation performance?

A: Fiber type: Standard G.657.A1/A2 single-mode fiber, compatible with G.652, supports high-bend scenarios (such as building corners).
Attenuation: ≤0.36/0.22 dB/km (1310nm/1550nm bands), ensuring low signal loss.
6. Are prefabricated terminations available? What plug types are available?

A: Single-ended and double-ended prefabricated terminations are supported, with optional SC/UPC or SC/APC plugs. Various waterproof and through-wall prefabricated terminations are also available.
UPC plugs: spherically polished end face, return loss ≥ 47dB;
APC plugs: 8° beveled end face, return loss ≥ 55dB, suitable for demanding scenarios such as HD video.
7. What is the mechanical performance of the optical bow-type drop cable?

A: It has undergone multiple rigorous tests:
Compressive strength: 1000N/100mm long-term, 2000N/100mm short-term;
Impact resistance: 2.94N-m (26 in-lb);
Flame-retardant jacket: Meets LSZH/PVC standards, reducing fire risks.
8. How can I quickly distinguish between different telecom companies' self-supporting bow cables after installation?

A: We can add color-coded identification strips based on customer needs.
9. How do you inspect fiber cable quality? How do you troubleshoot fiber breaks after installation?

A: Inspection: Use an OTDR to measure attenuation and verify that the tension/bend radius complies with Specification 710.
Fiber break troubleshooting:
1. Check for over-span installation;
2. Confirm that meteorological parameters match the design (e.g., if ice coverage is ≥10mm, the Class II standard must be met);
3. Eliminate damage caused by improper construction tools;
4. Check for bending, twisting, or squeezing during installation.
10. What are the packaging specifications and custom length requirements for outdoor self-supporting fiber optic cables?

A: You can choose between multi-layer composite wood or plastic reels.
Common reel lengths include 1000 feet, 500 meters, 1000 meters, and 2000 meters.
11. My purchase quantity is relatively small. Can we customize cable for me?

A: Of course. We support small-batch customization and can provide tailored solutions based on your specific needs to meet your specific usage scenarios.
12. Can products ordered from other factories be shipped to your company for loading together?

A: Of course. If you agree, we can also inspect the goods and pack them together for you.
