GJYXFCH 2FRP+1Steel Wire Messenger Outdoor FTTH Drop Cable

GJYXFCH Steel Messenger Wire FRP Strength Member Aerial Self-Supporting Mini FIG8 FTTH Drop Fiber Optic Cable

Overview:

GJYXFCH is an aerial self-supporting mini figure-8 (FIG8) FTTH drop fiber optic cable featuring a steel messenger wire and FRP (Fiberglass Reinforced Plastic) strength members. It is specifically designed for the "last-mile" fiber-to-the-home (FTTH) deployment, enabling direct fiber connection from distribution points to end-user premises. Its integrated self-supporting structure, easy-stripping design, and excellent environmental adaptability make it a core product in FTTH access networks.

• Structural Shape: Adopts a mini "figure-8" (FIG8) cross-section. The upper groove houses a steel messenger wire (for load-bearing and tension resistance), while the lower groove contains the fiber unit (with FRP strength members and optical fibers).

• Core Configuration: Typically supports 1–4 cores of single-mode optical fibers, compatible with mainstream standards such as G.657A1, G.657A2, and G.652D. Fiber coloring complies with TIA/EIA-598 or IEC 60304 standards (e.g., blue, orange, green, brown for core identification).

• Outer Sheath: Made of LSZH (Low Smoke Zero Halogen) material; optional UV (ultraviolet) resistant coating is available for long-term outdoor exposure scenarios.

• Dimensions: Compact size with an approximate outer diameter of 5.0×2.0 mm, suitable for narrow-space installation (e.g., along building exteriors, eaves).

Advantages of GJYXFCH Aerial Self-supporting FTTH Drop Fiber Cable:

As a specialized aerial drop cable designed for the "last kilometer" of FTTH (Fiber to the Home) networks, the GJYXFCH cable delivers unique advantages centered on installation convenience, environmental adaptability, transmission reliability, and safety compliance. These strengths are precisely tailored to outdoor aerial scenarios and home access requirements, with six key benefits detailed below:

1. Self-supporting Design: Eliminates Additional Suspension Costs & Simplifies Aerial Construction

• No separate messenger wire brackets are needed during installation. The cable can be directly tensioned and fixed between supports such as utility poles or building exteriors, significantly reducing the consumption of auxiliary materials (e.g., messenger wires, fasteners) and construction steps. For aerial scenarios in rural or suburban areas, this design improves construction efficiency by over 30% per kilometer.

• The steel messenger wire offers stable tensile performance: standard models support spans of up to 50 meters, while enhanced versions can meet short-distance crossings of 80 meters, adapting to aerial coverage needs in most residential areas and industrial parks.

  
  

2. Figure-8 Structure & Easy-Stripping Design: Accelerates "Last-Meter" Home Entry & Termination

• No complex tools are required: a dedicated wire stripper or utility knife can quickly peel off the sheath along the grooves to expose fibers and strength members, avoiding fiber core damage. A single operator can complete stripping in just 10–20 seconds.

• It is fully compatible with common FTTH termination processes, including "cold splicing" (mechanical splicing) and "hot splicing" (fusion splicing). Especially when paired with figure-8 dedicated connectors (e.g., SC/APC, LC/APC), the insertion loss after termination is ≤0.3dB, meeting transmission requirements for home broadband, IPTV, and other high-definition services.

  
  

3. Excellent Flexibility: Adapts to Complex Home Entry Routes

• The minimum static bending radius is only 7.5mm (roughly the thickness of an adult’s thumb), and the dynamic bending radius is ≥15mm. This allows flexible routing in narrow spaces such as building corners, pipeline bends, and home distribution boxes—no need to reserve large-radius paths, reducing construction constraints (e.g., avoiding wall or ceiling damage during home entry).

• Signal attenuation remains stable after bending: within the temperature range of -40℃ to +70℃, the change in bending loss is ≤0.1dB, ensuring no degradation in transmission performance during long-term use.

  
  

4. LSZH Sheath: Balances Environmental Protection & Safety for Indoor-Outdoor Transition

• When burned, it releases no toxic halogens (e.g., chlorine, bromine) or corrosive gases, and produces extremely low smoke density. Even in the event of a fire in enclosed spaces (e.g., building shafts, basements), it minimizes harm to personnel. Compliant with standards such as GB/T 17650.2, it supports integrated routing from "outdoor aerial to indoor home entry" (no need to replace with indoor cables at wall penetrations).

• The sheath is added with UV (ultraviolet) stabilizers, preventing aging and cracking during long-term outdoor exposure to sunlight, with a service life of over 20 years. It also has moderate resistance to acids, alkalis, and weather, adapting to complex climates (e.g., heavy rain, high dust, extreme temperature differences).

  
  

5. Dual Reinforcement Protection: Enhances Cable Damage Resistance

• These strength members resist radial compression (e.g., stepping during construction, impact from foreign objects) and longitudinal tension (e.g., slight swaying during aerial use), preventing transmission loss caused by fiber core deformation due to external forces.

• The steel messenger wire and internal strength members form "dual protection": even if the messenger wire is slightly deformed by accidental force, the internal strength members still protect the fiber core, reducing failure risks in outdoor use.

  
  

6. High Compatibility & Standardization: Adapts to Global FTTH Network Systems

• It meets China’s YD/T 1997-2009 Figure-8 Drop Cable for Access Networks and international standards such as IEC 60794-1-2, enabling seamless integration with OLT (Optical Line Terminal) and ONU (Optical Network Unit) equipment from major manufacturers (e.g., Huawei, ZTE, FiberHome) without compatibility issues.

• Fiber counts are flexible (1core, 2core as standard; 4core customizable), meeting both basic "single-fiber home entry" needs for individual households and multi-core access requirements for multi-service scenarios (e.g., broadband + surveillance + smart home), supporting future home network upgrades.

Applications:

1. Aerial Building-to-Building Connection: Installed between utility poles or building rooftops to connect fiber distribution boxes (FDBs) across residential communities, industrial parks, or campuses.

2. Pole-to-Building Aerial Drop: From street utility poles to the exterior walls of residential/commercial buildings, then routed along eaves or wall-mounted cable trays to enter the building.

3. Indoor-Outdoor Transition: After aerial deployment to the building exterior, the fiber unit (separated from the steel messenger wire) is routed through wall penetrations, cable shafts, or indoor (trays) to reach user-specific optical network terminals (ONTs).

4. Narrow-Space Installation: Suitable for old communities or dense urban areas where installation space is limited (e.g., along narrow building gaps, under eaves).

Selection & Installation Tips:

1. Core Count Selection: Choose 1–2 cores for single-user homes; 4 cores for multi-dwelling units (MDUs) or scenarios requiring backup fibers.

2. Environmental Matching: Select UV-resistant models for long-term outdoor use; choose extended temperature-range versions for cold regions (-40°C) or high-temperature areas.

3. Mechanical Requirement Check: For longer aerial spans (e.g., >50 meters), confirm the cable's long-term tensile strength with the manufacturer to avoid sagging or breakage.

4. Installation Precautions:

• Reserve 5–10% length for thermal expansion/contraction when installing in areas with large temperature fluctuations.

• Maintain a minimum bending radius (≥15 mm) during routing to avoid fiber damage.

• Secure the steel messenger wire at fixed intervals (recommended ≤20 meters) to prevent excessive tension on the fiber unit.
