This reliable Round Type Drop Cable  is specifically engineered as a resilient backbone for FTTH and FTTx applications. Its durable, UV-resistant design supports aerial, duct, and micro-duct installation methods. Constructed with G.657.A1 bend-insensitive fiber and high-strength reinforcement elements, the cable ensures long-lasting, high-performance deployment for residential and rural broadband projects.

By offering unified performance specifications, this product eliminates the need for separate indoor and outdoor cables. Its robust 8.7 mm LSZH (Low Smoke Zero Halogen) jacket not only fully complies with stringent indoor fire safety standards (IEC 60332-1) but also offers excellent UV resistance for outdoor environments. This continuous cable run effectively connects outdoor lines with indoor wiring, thereby reducing splice points and the need for additional transition hardware.

Premium Cable Structure

Technical Performance and Environmental Resilience

With a compact 8.7 mm diameter, this ftth round type drop cable features a robust, UV-resistant HDPE outer jacket. This durable construction allows installers to seamlessly route the cable through underground pipes, conduits, or tight aerial pathways while ensuring long-term resistance to harsh outdoor climates.

Mechanical Reinforcement and Versatile Deployment
To ensure exceptional structural stability, the cable integrates dual FRP rods and heavy-duty aramid yarns as its primary strength members. This mechanical reinforcement delivers the high tensile strength required for reliable aerial installations, last-mile drops, and air-blown micro-duct deployments.

While the tough HDPE sheath withstands severe weathering, the cable retains enough flexibility to transition smoothly into subscriber premises for direct indoor ONT (Optical Network Terminal) wiring.

Efficient Installation and Material Safety
The slim 8.7 mm profile lowers surface friction during pulling, which accelerates installation and minimizes the risk of micro-bending losses or physical jacket damage.

For projects requiring specialized compliance, we also offer alternative material grades, including flame-retardant and FRNC (Flame Retardant Non-Corrosive) options. These configurations make the cable fully suitable for indoor-outdoor transition zones, meeting strict fire safety standards across diverse building environments.

Q. What is an FTTH round type drop cable?

A: An FTTH round type drop cable is a compact, circular optical fiber cable designed for last-mile connections in Fiber-to-the-Home networks. Unlike traditional flat drop cables, its all-dielectric round structure offers multi-directional flexibility, making it much easier to route through tight bends, conduits, and complex indoor/outdoor pathways without kinking.

Q. What are the benefits of a tight-buffered fiber cable design?

A: A tight-buffered design (typically featuring a 900 µm buffer layer) encases the fiber core directly to provide excellent mechanical protection and crush resistance. For installers, the main benefit is convenience—it allows for direct stripping and fast termination with standard connectors (like SC/APC or LC/UPC) without needing separate fan-out kits or messy gels.

Q. Can this round drop cable be used both indoors and outdoors?

A: Yes. This universal round drop cable is engineered to eliminate the need for transition splicing between outdoor plants and indoor wiring. It features a 3.0 mm LSZH (Low Smoke Zero Halogen) jacket that complies with indoor fire safety standards (IEC 60332-1) while offering robust UV resistance and weatherability for outdoor exposure.

Q. Why does this cable use G.657.A2 bend-insensitive fiber?

A: G.657.A2 fiber is chosen for its extreme flexibility and low bend radius (dynamic < 20 mm, static < 10 mm). This ensures the cable maintains stable, low-attenuation signal transmission even when sharply bent around wall corners or tightly packed inside subscriber premises and distribution boxes.

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.
