The Universal Round Type Drop Cable With Tight-buffered offers a premium single-fiber solution optimized for FTTH last-mile connectivity. Seamlessly linking distribution terminals to subscriber premises, this versatile ftth round type drop cable features advanced G.657.A2 bend-insensitive fiber to ensure minimal signal loss within tight bends and confined spaces.

By unifying performance specifications, it completely eliminates the need for separate indoor and outdoor cable variants. The robust 3.0 mm LSZH (Low Smoke Zero Halogen) jacket complies fully with strict indoor fire safety standards (IEC 60332-1) while delivering excellent UV resistance for open outdoor environments. Implementing this continuous cable run effectively bridges outdoor plants and indoor wiring, minimizing splice points and reducing the need for extra transition hardware.

Premium Cable Structure

  • Colored Fiber: Positioned at the absolute center, this core transmission medium utilizes high-grade G.657.A2 optical fiber. It guarantees reliable signal transmission with reduced attenuation, performing flawlessly even in severely bent or high-density deployment setups.

  • Buffer Layer: A protective 900 µm tight-buffered layer securely encases the center fiber. This design dampens external mechanical stress and enables installers to handle direct stripping and rapid termination easily without specialized fan-out kits.

  • Aramid Yarns: Serving as the primary strength members, heavy-duty aramid yarns wrap around the buffer layer. They supply exceptional tensile strength and superior crush resistance while keeping this ftth round type drop cable lightweight and highly flexible.

  • TPU/LSZH Sheath: The durable outer jacket comes in either TPU or LSZH material. This layer provides essential flame-retardant, low-smoke, and zero-halogen properties for indoor safety compliance, alongside excellent wear and weather resistance for dependable outdoor routing.

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.

Applications & Deployment Solutions

  • Simplified installation – One cable type covers both outdoor drop and indoor riser runs; tight buffer enables fast connectorization (≤ 2 min per termination) without intermediate splices.
  • Durable across environments – Aramid reinforcement and UV‑resistant jacket tolerate outdoor sun exposure and indoor temperature variations (‑20°C to +60°C typical; actual range depends on jacket grade). The LSZH compound reduces toxic smoke and acid gas in fire, improving occupant safety.
  • Space‑efficient routing – High flexibility and small bending radius allow neat routing through corners, ducts, and risers in MDUs or enterprise buildings.
  • Dielectric construction – No metallic components, eliminating lightning‑induced surge risks in overhead or building entries.
  • Applications
  • FTTH drop connections from optical distribution points (ODPs) to home gateways or ONTs.
  • FTTx distribution in multi‑dwelling units (MDU), campus buildings, or office floors — for indoor riser, vertical shaft, and horizontal duct runs.
  • Short‑haul enterprise LAN backbones and telecom rooms where a single cable must pass through indoor/outdoor boundary walls.
  • Replacement for separate indoor and outdoor patch cords in space‑constrained data centers or equipment cabinets.
