皮线 GJYXCH-1F

Overview:

GJYXCH is a self-supporting aerial FTTH (Fiber to the Home) drop cable featuring an integrated "figure-8" structure, combining a steel messenger wire with the cable body which contains two steel wire strength member. It is specifically designed for outdoor aerial deployment and last-mile fiber access to residential or commercial premises, typically available with 1–4 fiber cores and an outer diameter of approximately 2.0*5.0 mm.

Typical Structure:

The cable adopts a layered, figure-8 structure to balance mechanical performance and transmission efficiency:

Fiber Core (Center): 1–4 core single-mode fibers (common types: G.657.A2/A1 or G.652.D).

G.657.A2: Excellent bend resistance (minimum bend radius: 7.5 mm static / 15 mm dynamic), ideal for tight routing in indoor/outdoor transitions.
G.652.D: Universal single-mode fiber, compatible with long-haul and access networks.

Strength Members: Two parallel rods (steel or FRP) placed symmetrically on both sides of the fiber core, providing radial compression resistance and anti-bending support.
Steel Messenger Wire: An independent high-tensile steel wire integrated into one "lobe" of the figure-8 structure, bearing the main tension during aerial installation (e.g., spanning between utility poles).
Sheath: Black LSZH outer sheath, covering the fiber core, strength members, and connecting to the messenger wire. It provides UV resistance, water resistance, and environmental protection.

Features:

Self-Supporting Aerial Capability: The integrated steel messenger wire eliminates the need for additional suspension cables, reducing installation complexity and cost for outdoor aerial spans.
Superior Bend Performance: G.657.A2 fiber supports small-radius bending, enabling flexible routing around corners, walls, or tight spaces during last-mile (home entry).
Easy Installation & Termination: The butterfly-shaped structure has a pre-designed groove for quick longitudinal stripping, allowing fast termination with fusion splicers or mechanical splice-on connectors (SOCs).
Environmental & Safety Compliance: LSZH sheath produces low smoke and zero toxic halogens when burned, making it safe for indoor/outdoor transition areas (e.g., building shafts, basements).
Broad Standard Compatibility: Meets international and industry standards, including YD/T 1997-2009 (China), IEC 60794 (International Electrotechnical Commission), and GR-409/ICEA-596 (North America), ensuring interoperability with global FTTH systems.
Wide Temperature Range: Operates reliably in harsh environments, typically from -40 °C to +70 °C, suitable for most climates.

Applications:

FTTH Last-Mile Access: Aerial deployment from neighborhood distribution points (e.g., utility poles, fiber cabinets) directly to residential buildings or individual homes.
Short-Distance Outdoor Connections: Interconnection between small-scale network nodes in industrial parks, residential communities, or campuses (span length typically ≤ 50 meters).
Indoor-Outdoor Transition: Vertical routing in building shafts or horizontal wall-mounted installation, bridging outdoor aerial lines to indoor fiber outlets.
Rural/Suburban Fiber Networks: Cost-effective solution for areas with sparse population, where aerial installation is more feasible than underground cabling.

FAQs:

Q1: What's the structural difference between GJYXCH and FRP type GJYXFCH?

A: GJYXCH uses two parallel solid steel wires as inner strength members, while GJYXFCH adopts dual FRP rods. All-in-steel structure delivers much higher tensile capacity for long-span overhead installation.

Q2: Available fiber core quantity and fiber types?

A: Standard 1/2/4 cores single-mode fiber; compatible with G.652D, G.657A1, G.657A2 bend-resistant fiber, matching regular FTTH home wiring requirements.

Q3: What sheath material is applied for GJYXCH? Indoor usable?

A: Standard outer sheath is LSZH low smoke zero halogen flame retardant. Safe for indoor routing after outdoor aerial entry. UV-resistant LSZH is optional for permanent open-air overhead installation against sunshine aging.

Q4: Does this figure-8 cable support tool-free stripping?

A: Pre-set tear slot along sheath. Workers can split sheath by hand, separate top steel messenger and bottom fiber unit easily without special stripping tools to improve field termination efficiency.

Q5: Recommended maximum aerial span distance?

A: Regular safe overhead span: 40–60m. Spans exceeding 60m need customized high-tensile specification and matched fixing hardware.
