ASU Custom Span Fiber Optic Cable is an all-dielectric self-supporting aerial fiber cable designed for power distribution and telecommunication networks. Built with dual FRP strength members and an HDPE outer jacket, it delivers stable optical transmission for short and medium spans while eliminating grounding requirements near high-voltage lines.
Engineering Highlights & Benefits
Customized Span Design: Tailored FRP diameters and sheath thickness optimize tensile performance for target pole distances, reducing unnecessary cable weight and installation costs.
Non-Metallic Grounding Safety: Dual FRP rods ensure complete dielectric isolation, preventing lightning strikes and inductive interference along power lines.
Environmental Sheath Protection: High-density polyethylene (HDPE) protects against UV, moisture, and temperature fluctuations. Anti-Tracking PE is available for environments adjacent to high-voltage lines.
Signal Stability: PBT loose tubes with water-blocking gel shield fibers from mechanical stress and moisture ingress, maintaining low attenuation over long lifespans.
Quality Control & Inspection
Every production batch undergoes Factory Acceptance Testing (FAT) to ensure compliance with optical and mechanical standards:
Optical Testing: Attenuation spectrum and fiber continuity check
Mechanical Testing: Tensile strength, crush resistance, impact, and repeated bending
Environmental Testing: Temperature cycling (-40°C to +70°C) and water penetration
Physical Inspection: Jacket thickness, cable outer diameter, and meter mark legibility

ASU cable is one loose tube stranded. Fibers, 250um , are positioned into a loose tube made of high modulus plastics. Two FRP (Fiber Reinforced Plastic) as as strengthen member. Cable surface is extruded with HDPE (polyethylene) sheath.
FAQ
Q: How do I select the right cable structure for my specific pole distance?
A: Provide us with your pole spacing, local maximum wind speed, and ice-loading conditions. Our engineering team calculates the required FRP strength member size and tensile rating to fit your exact span requirement.
Q: What fiber brands and optical standards are supported?
A: We supply premium single-mode (G.652D, G.655, G.657A1/A2) and multimode (OM2, OM3, OM4) fibers from YOFC, Corning, FiberHome, or Sumitomo based on project requisites.
Q: When should I choose an Anti-Tracking PE sheath instead of standard HDPE?
A: Standard HDPE is suitable for telecommunication lines and low-voltage distribution. If the cable is installed near high-voltage lines where space potential exceeds electrical thresholds, Anti-Tracking PE is recommended to prevent jacket erosion caused by electric arcs.
Q: What quality documentation accompanies each shipment?
A: Every drum is delivered with a Factory Acceptance Test (FAT) report detailing optical attenuation readings, structural dimensions, and batch tracking serial numbers.
Q: What packaging measures protect the cable during international sea freight?
A: Cables are wound on heavy-duty wooden or steel-wooden drums, sealed with protective waterproof wrapping, and fitted with end caps to prevent moisture ingress during shipping and storage.
