Fiber Optic Kabel

All dielectric non-metal flat fiber optic cable
Flat fiber optic cable ,optical fibers are housed in a loose tube that is made of high-modulus plastic and filled with jelly. Two FRP are placed in parallel outside the tube, and a flat-shape PE sheath is extruded.

Core Mechanical and Environmental Standard Parameters

(National Standard YD/T 1997)

External Dimensions

approximately 7.3mm (width) × 4.2mm (thickness), weight ≈31kg/km, much lighter than round overhead optical cables.

Tensile Strength

- Long-term Allowable Tensile Strength: 400N
- Short-term Damaging Tensile Strength: 1400N

Compressive Strength

Long-term Compressive Strength: 1000N/10cm
- Short-term Compressive Strength: 5000N/10cm, not easily damaged by external wall fixing or foot traffic.

Bending Radius

- Static Laying (Long-term Fixed): ≥15 times the cable thickness
- Dynamic Construction Traction: ≥30 times the cable thickness Bending is only permitted along a flat plane; sharp bends perpendicular to a flat plane are strictly prohibited.

Operating Temperature Range

Operating: **-40℃ ~ +70℃**; Storage: -40~+70℃, suitable for both frigid northern regions and direct sunlight in southern regions.

Core Product Advantages

Choose the cables that suits you best.

All Non-Metallic Lightning Protection

Specifically for Rural and Mountainous Areas, With no metal components, it eliminates the need for grounding when used on overhead power poles near high-voltage lines or in areas prone to lightning strikes, preventing damage to equipment from induced lightning strikes.

Loose Tube Waterproofing

Superior Outdoor Waterproofing Compared to Ordinary 2-Core Drop Cables** Ordinary outdoor drop cables use tightly bundled optical fibers without fiber paste; GYFXBY loose tubes and water-blocking yarn provide double waterproofing, ensuring stable attenuation even under long-term exposure to rain and outdoor fiber distribution boxes, reducing the risk of water ingress and fiber breakage.

Self-Supporting

No Suspension Wire Required, Significantly Reducing Construction Costs** The FRP panels on both sides have built-in tensile strength, allowing direct hanging from poles and wall supports using wedge clamps, eliminating the need for additional galvanized steel suspension wires. This halves the cost of long-distance wiring to rural homes.

Black HDPE Weather-Resistant and Anti-Aging

The sheath remains crack-free and powder-free after 5-8 years of outdoor exposure, resisting rain, bird damage, and minor chemical corrosion.

Laying Precautions

(Key Prohibitions)

Only planar bending is supported .Strong bending of the flat cross-section is prohibited, as it can easily crush the loose conduit and damage the optical fiber.

The recommended overhead span is ≤80 meters. In areas with heavy snow or ice, shorten it to within 50 meters to avoid overload.

Do not directly bury in road surfaces where heavy vehicles are present; without conduit protection, the fiber is easily crushed.

The HDPE sheath is not flame-retardant. Its use is strictly prohibited in enclosed spaces such as corridors and basements. Use GJXH for indoor installations.

The pulling force during traction must not exceed a long-term value of 400N, and the instantaneous pulling force during construction should not exceed 1400N.

Fiber optic cable must be secured using dedicated wedge-shaped self-supporting clamps; do not rely solely on clamping the sheath for support.

Package of Flat cable

plywooden drum

why choose our products

This optical cable is lightweight, so it is typically packaged in three-ply wooden crates with cardboard, which is cost-effective and provides excellent protection for the cable.The panel can be customized to print your logo and text.
