GYFXTBY All Dielectric FTTH Flat Oval Drop Cable

GYFXTBY All Dielectric No-Metal FTTH Flat Oval Drop Cable

Flat ADSS Fiber Optic Cable

GYFXTBY is a flat-shaped ADSS (All-Dielectric Self-Supporting) oval drop fiber optic cable specifically designed for "last-mile" access networks. It integrates the self-supporting advantage of ADSS cables with the flat, compact design of drop cables, making it ideal for connecting distribution points to end-users (e.g., homes, offices, or small businesses). Unlike traditional round cables, its flat oval structure optimizes installation in narrow spaces and reduces wind load, while the all-dielectric construction eliminates the need for metal components (avoiding corrosion and electromagnetic interference).

Product Overview:

• Product Category: Specialized access network cable (belongs to the ADSS cable family, optimized for drop applications).

• Core Function: Transmits high-speed optical signals (data, voice, video) in the "last mile" of fiber-to-the-home (FTTH), fiber-to-the-building (FTTB), or fiber-to-the-premises (FTTP) networks.

• Key Differentiator: Combines three critical features:

1. ADSS (All-Dielectric): No metal conductors (e.g., steel wires), ensuring resistance to corrosion, lightning, and electromagnetic interference (EMI).

2. Flat Oval Shape: Slim profile for easy installation in tight spaces (e.g., along walls, in cable ducts, or attached to utility poles).

3. Drop Cable Design: Lightweight and flexible, tailored for short-distance connections from distribution cabinets to end-user premises.

Major Characteristics of GYFXTBY Oval Drop Cable:

① All-Dielectric & EMI Resistant

• No metal components, so it is immune to electromagnetic interference (EMI) from power lines, motors, or radio signals.

• Suitable for installation near high-voltage power cables (common in overhead utility poles) and avoids corrosion in humid or coastal environments.

② Self-Supporting (ADSS Advantage)

• Reinforced with FRP rods, it can support its own weight during overhead installation (e.g., between utility poles or building exteriors) without relying on additional support cables.

• Tensile strength ranges from 600–1800N (depending on the size of FRP ), meeting short-distance self-support requirements.

③ Flat & Compact Design

• Slim flat profile minimizes space occupancy: easy to install in wall-mounted ducts, under floorboards, or along building facades (no bulky round cables).

• Reduces wind load and ice accumulation during outdoor overhead use, lowering maintenance costs.

④ High Signal Stability

• The central buffer tube and non-metallic reinforcement reduce microbending loss (signal attenuation caused by fiber deformation), ensuring stable transmission (attenuation ≤0.36dB/km for SM fibers at 1310nm).

• Temperature resistance: Operates in -40°C to +70°C, suitable for both cold and hot climates.

⑤  Easy to Install & Maintain

• Lightweight and flexible, easy for quick installation and labor-saving.

• The flat shape allows easy identification and tracing during maintenance (no confusion with other round cables).

Typical Applications:

① Fiber-to-the-Home (FTTH)

• Connects neighborhood distribution cabinets (ODNs, Optical Distribution Networks) to individual homes:

• Overhead installation: Strung between utility poles and attached to home exteriors.

• Indoor installation: Run through wall ducts or under floors to connect to ONUs (Optical Network Units) inside homes.

② Fiber-to-the-Building (FTTB)

• Used in multi-story buildings to link the building’s main distribution frame (MDF) to each floor’s distribution box, then to individual offices or apartments.

• Ideal for retrofitting old buildings where space for cabling is limited (flat profile fits in existing narrow ducts).

③ Outdoor Access Networks (Residential/Industrial Zones)

• Overhead installation in suburban or rural areas (e.g., between utility poles) to extend fiber coverage to scattered homes or small factories.

• Resistant to UV, moisture, and EMI, making it suitable for outdoor use without additional protective sleeves.

④ Indoor Cabling in Public Spaces

• Installed in shopping malls, hotels, or hospitals to connect access points (e.g., WiFi routers, IP cameras) to the core network.

• Flame-retardant LSZH sheath ensures compliance with fire safety codes for public buildings.

⑤ Temporary or Emergency Networks

• Lightweight and easy to deploy for temporary events (e.g., concerts, exhibitions) or emergency communication (e.g., after natural disasters) where quick, temporary fiber links are needed.

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.

FAQ:

What are the typical installation methods for GYFXTBY fiber optic cable?

GYFXTBY, as an all-dielectric self-supporting (ADSS) oval flat drop cable, is designed for flexibility in FTTH/FTTx "last-mile" scenarios. Its installation methods are tailored to its structural features (lightweight, flat shape, FRP reinforcement) and application needs (aerial, duct, or direct indoor/outdoor routing). Below are the 4 most common installation methods, along with key operational details and precautions.

1. Aerial Self-Supporting Installation (Most Common)

Key Steps:

1. Pre-installation Preparation:

• Inspect utility poles (stability, load capacity) and clear obstacles (tree branches, existing cables) along the route.

• Prepare tools: wedge clamps (matched to GYFXTBY cable's flat shape), cable pay-off stands, tension meters, and fiber optic strippers.

2. Cable Routing & Tension Control:

• Deploy the cable from the pay-off stand, maintaining a constant tension (typically 50–100 N, depending on core count) to avoid overstretching.

• Use wedge clamps to fix the cable to utility poles: position clamps at pole tops or designated brackets, ensuring the flat side of the cable is aligned with the clamp to prevent slippage.

3. Span & Sag Adjustment:

• For short spans (≤50 meters, common in residential areas), set a small sag (5–10 cm) to accommodate temperature changes (expansion in summer, contraction in winter).

• For longer spans (50–100 meters), use tension meters to fine-tune sag and avoid excessive stress on the cable.

4. Termination & Protection:

• At the end of the aerial span (e.g., near a building), use a cable entry box to transition the cable from aerial to indoor/duct routing. Seal the box to prevent water intrusion.

Precautions:

• Avoid small-radius bending (minimum static bend radius: ≥10× cable diameter; dynamic: ≥20×) during installation.

• Keep the cable at least 0.5 meters away from high-voltage power lines to reduce electromagnetic interference (EMI), even though GYFXTBY is all-dielectric.

  
  

2. Duct Installation

Key Steps:

1. Duct Inspection & Preparation:

• Check duct integrity (no cracks, blockages) using a duct rodder. Clean the duct with compressed air or a duct brush to remove dust or debris.

• Install a pull rope (nylon or polyester) inside the duct using a duct rodder—this rope will pull the GYFXTBY cable through.

2. Cable Pulling:

• Attach the cable’s leading end to the pull rope using a cable pulling grip (ensure a secure connection to avoid detachment mid-pull).

• Use a manual or electric cable puller to pull the cable at a steady speed (≤5 meters per minute). For long ducts (>100 meters), add intermediate pull points to reduce friction.

3. Duct Sealing & Marking:

• After pulling, seal both ends of the duct with waterproof tape or duct seals to prevent water, rodents, or debris from entering.

• Mark duct access points (e.g., manholes, handholes) with labels indicating "GYFXTBY Fiber Optic Cable" for future maintenance.

Precautions:

• Use a lubricant (compatible with HDPE sheaths) for long or curved ducts to reduce friction and avoid sheath damage.

• Do not pull the cable at an angle—keep it aligned with the duct axis to prevent kinking.

  
  

3. Wall-Mounted Installation

Key Steps:

1. Route Planning:

• Mark the wall route (e.g., along corners, under eaves) to avoid obstacles (electrical outlets, water pipes) and ensure a neat appearance.

2. Fixing with Cable Clips:

• Use adhesive cable clips (for smooth walls like concrete or tile) or screwed clips (for rough walls like brick) matched to GYFXTBY’s flat width.

• Space clips 30–50 cm apart to secure the cable and prevent sagging. Ensure the cable is not compressed by the clips (avoid over-tightening).

3. Entry into Buildings:

• Drill a small hole (diameter: 10–15 mm) through the wall at the entry point. Install a waterproof grommet in the hole to protect the cable from water and sharp edges.

• Pull the cable through the grommet and into the indoor distribution box (e.g., ONU box).

Precautions:

• For outdoor walls, use UV-resistant cable clips to prevent degradation from sunlight.

• Avoid mounting the cable near heat sources (e.g., air conditioner outdoor units) to prevent sheath softening.
