The Butterfly Flat FTTH Drop Optical Cable features a flat, butterfly-shaped design. This structure includes a central optical fiber unit flanked by two Fiber Reinforced Plastic (FRP) strength members. Additionally, a Low-Smoke Zero-Halogen (LSZH) jacket encases the cable. As a result, it effectively resists environmental factors like moisture, temperature fluctuations, and UV radiation.

Compared to standard indoor cables, this flat-drop FTTH optical cable provides greater data transmission bandwidth and superior interference resistance. Therefore, it is the perfect choice to connect homes and businesses to the fiber backbone network.

Furthermore, its slim profile, waterproof nature, and high flexibility facilitate easy deployment and maintenance. Because it uses a non-metallic strength member, the design ensures robust protection against lightning and electromagnetic interference. Finally, its flat, rectangular shape allows for neat installation along wall surfaces. Consequently, this cable is perfectly suited for both Fiber-to-the-Home (FTTH) and Fiber-to-the-Building (FTTB) applications.

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.
