Universal Flat Drop Cable With Single Fiber

Suitable for direct buried, aerial or duct installation
G.657.A1 bend resistant fiber
High tensile & crush strength
UV‑resistant outdoor sheath

Universal Flat Drop Cable With Single Fiber meets all your needs for Fiber to the Home (FTTH) and versatile FTTx network deployments. This premium, all-dielectric, and UV-resistant solution features a unique arc-runway flat profile. It delivers exceptional reliability and flexibility for modern access networks.

The cable features a central, bend-insensitive G.657.A1 tight-buffered fiber. Twin 1.5 mm strength members flank the core to deliver high tensile strength and dimensional stability. An integrated 24 AWG copper conductor provides reliable post-burial traceability. Finally, a rugged, black UV-resistant PE sheath with water-blocking properties encloses all components. This makes the design ideal for direct burial and demanding outdoor environments.

Premium Cable Structure

Central Tight-Buffered Fiber: This core element uses premium, bend-insensitive G.657.A1 fiber. It ensures exceptional signal transmission, lower attenuation, and superior reliability even in tight-bending drop environments.
Water-Blocking Protection: Advanced water-blocking properties guard the core elements. This design effectively blocks longitudinal moisture ingress and protects the fiber from water damage in underground environments.
Parallel Strength Members: Twin 1.5 mm FRP rods sit symmetrically on both sides of the optical fiber. They deliver outstanding tensile strength, prevent elongation, and ensure structural stability during installation.
Durable Outer Sheath: A rugged, black, UV-resistant Polyethylene (PE) jacket encloses the entire cable. The flat profile resists mechanical wear, environmental stress-cracking, and extreme weather during direct burial.

Q: What is the maximum span length for aerial installation with this flat drop cable?

A: This flat drop cable is primarily engineered for short-span applications (typically up to 50 meters / 164 feet, depending on local wind and ice load conditions). Its lightweight, flat profile significantly minimizes wind load, making it ideal for rural FTTH deployment and pole-to-building drop routing.

Q: What are the tensile strength and crush resistance ratings?

A: The cable features robust MB-coated FRP strength members, allowing it to withstand a maximum rated design tension of up to 3 kN (674 lb) and a crushing load resistance of 0.4 kN/cm (228 lb/in). This ensures the fiber cores remain fully protected during pulling and under environmental stress.

Q: What type of fiber cores do you use, and can I choose the fiber count?

A: We use standard 250um colored coating fibers (typically G. 657. A1 or G.657.A2 bend-insensitive fiber for tight FTTH routing). Our standard configuration supports 1 to 12 cores inside the central loose tube, and it can be customized/expanded up to 24 cores upon request.

Q: Is this cable fully waterproof for underground or sewer applications?

A: Yes. The central loose tube is internally filled with a thixotropic water-blocking gel (or water-blocking compound). This design effectively prevents longitudinal water penetration, making the cable perfectly reliable for underground ducts, drainage pipes, and direct burial.

Q: Can it withstand extreme weather conditions, such as high UV or freezing temperatures?

A: Absolutely. The outer jacket is made of co-extruded High-Density Polyethylene (HDPE), which provides superior UV protection, wear resistance, and environmental stress-cracking resistance. It has a wide operating temperature range from (-40 °C to +70 °C (-40 °F to +158 °F)), suited for diverse global climates.

Q: Does this cable require grounding?

A: No, grounding is not required. This is a 100% All-Dielectric (metal-free) cable. It utilizes FRP (Fiber Reinforced Plastic) as strength members instead of steel wire. This eliminates the risk of lightning strikes and electromagnetic interference (EMI), making it entirely safe and worry-free for direct burial or high-voltage corridor routing.

Q: How does the design save time during installation?

A: Two key features boost installation efficiency:

Flat Arc-Runway Profile: Easy to identify, align, and securely fasten with standard drop clamps.
Integrated Rip Cord: Placed right under the HDPE jacket, allowing installers to rapidly split and strip the outer sheath without damaging the internal loose tube.

Q: Can you customize the outer jacket color or print our logo on the cable?

A: Yes, we offer full OEM/ODM services for independent station buyers. We can customize the sheath marking (including your brand name, meter marks, and model number) and adjust the jacket material (e.g., LSZH for indoor-rated requests) based on your project requirements.

Q: What is the standard packaging and MOQ for this flat drop cable?

A: The cable is typically delivered on seaworthy wooden or plywood drums (standard lengths are 2 km or 4 km per drum). Our MOQ is negotiable depending on your specific fiber count and customization needs. Please Contact Us directly for a detailed quotation and MOQ options.
