GYFXTBY Non-metallic Oval Flat Drop Cable

GYFXTBY Non-metallic Aerial Oval Flat Drop Fiber Optic Cable

Product Overview:

GYFXTBY is an all-dielectric self-supporting (ADSS) oval flat drop fiber optic cable, specifically designed for the "last-mile" connection in FTTH/FTTx networks. It excels in user access and branch connections, featuring easy stripping, lateral pressure resistance, light weight, and lightning protection. It supports both aerial self-supporting installation and duct routing.

• Use: Aerial self-supporting drop/branch connection, enabling last-mile access to residential buildings, offices, or end-users.

• Structure: Oval flat outer shape, composed of a central loose tube, two parallel FRP strength members (on both sides), water-blocking yarn, and a PE outer sheath. Optional rip cords are available for quick on-site stripping.

• Fiber Count: Typically 2–24 cores, mainly using single-mode fibers (e.g. G.652D, the most common type for FTTH).

Key Structural Components:

Main Characteristics:

• Oval Flat & Lateral Pressure Resistance: The flat oval design minimizes sensitivity to trampling or extrusion, making it suitable for installation in narrow spaces (e.g., between building walls) and compatible with special clamps.

• Easy Construction: Small diameter, lightweight, and easy-to-strip sheath reduce labor intensity. It streamlines both aerial deployment and indoor/outdoor drop-into-user processes.

• All-Dielectric Design: No metal strength members, eliminating the risk of lightning-induced damage—ideal for lightning-prone areas (e.g., rural regions, high-altitude areas).

• Environmental & Mechanical Stability: Precise fiber excess length control and high-modulus loose tubes ensure stable optical attenuation (low signal loss) and geometric performance across temperature fluctuations (-40°C to +70°C) and mechanical stress.

Typical Applications:

• FTTH Last-Mile Access: Aerial self-supporting deployment from utility poles to residential buildings, villas, or office floors.

• Branch Distribution: Connecting distribution points to end-users in scenarios like rural networks, industrial parks, or residential communities.

• Duct/Wall-Mounted Routing: Can be used in conjunction with butterfly drop cables to form an integrated "aerial-to-indoor" solution, e.g., routed through underground ducts or attached to building exteriors.

Selection & Installation Recommendations:

• Fiber Count & Type: Choose 2–24 cores based on user density and future network expansion needs. G.652D single-mode fiber is preferred for its wide compatibility and low loss.

• Aerial Installation: Use matching wedge clamps for fixation; prioritize self-supporting routing. Avoid excessive tension or small-radius bending (minimum bend radius: ≥10x cable diameter for static use, ≥20x for dynamic use).

• User-End Protection: When routing into buildings, use protective conduits or concealed wall-mounted channels. Ensure waterproof sealing at the entry point (e.g., using waterproof glands) to prevent water or dust ingress.

FAQs:

Q1: What is the difference between GYFXTBY and ordinary round ADSS cable?

• GYFXTBY: Oval flat profile, smaller wind load, lighter weight, easier aerial lashing, dedicated for FTTH last-mile drop; shorter span, lower tensile requirement.

• ADSS: Round cable, designed for long-span overhead on power poles, higher tensile strength, usually for trunk/backbone lines.

  
  

Q2: Is GYFXTBY fully non-metallic? Any metal inside?

Yes, it is all dielectric (non-metallic). Reinforcement members are FRP (Fiber Reinforced Plastic), no steel wire, no metal tube. It avoids lightning induction and short-circuit risk when installed near power lines.

Q3: Do you provide test reports or certificates?

We can supply factory test report, ISO certificates

Q4: What's the MOQ?

Normally MOQ is 24 km, but small sample order also is available.

Q5: What's the delivery time for one container order?

Generally 15 - 20 working days.
