ASU Duct Outdoor Fiber Optic Cable is a lightweight all-dielectric optical cable designed for underground duct and short-span aerial deployments. Engineerd with dual FRP non-metallic strength members, a gel-filled central loose tube, and a high-density polyethylene (HDPE) outer jacket, it delivers stable signal transmission and long-term environmental protection for FTTH access, municipal networks, and utility communications.
Performance & Installation Advantages
Low Pulling Tension: Compact diameter and low weight reduce duct friction, enabling smoother pulling without damaging the cable jacket.
Total Dielectric Protection: Non-metallic FRP members eliminate electromagnetic interference, lightning risks, and grounding needs near power lines.
Complete Moisture Sealing: Gel-filled tubes combined with dry water-blocking materials prevent water penetration in flooded underground ducts.
Minimized Signal Attenuation: Continuous long-length delivery reduces field splicing points, preserving overall optical link quality.
Custom Manufacturing Options
Optical Fiber Selection: Specific glass brands, attenuation tiers, and custom core color sequences.
Sheath Customization: Low Smoke Zero Halogen (LSZH), Anti-Tracking (AT), or flame-retardant outer jackets.
Cable Surface Identification: Meter marking accuracy, custom text printing, sequence branding, and project codes.
Packaging & Reel Size: Tailored drum capacities (1km, 2km, 3km, 4km+) matching specific project duct layouts.
Quality Assurance
Every production batch undergoes mandatory factory acceptance testing prior to release:
OTDR attenuation checks at 1310nm / 1550nm for every fiber core.
Tensile loading tests and crush resistance evaluation under simulated field stress.
Temperature cycling (-40℃ to +70℃) and water penetration testing.
Outer sheath thickness measurement, dimensional tolerance verification, and visual drum inspection.
Manufacturing Capabilities
Precision Extrusion Lines: Automated control systems ensuring uniform loose tube dimensions and consistent jacket thickness.
Online Monitoring: Real-time attenuation tracking and dimensional control during the stranding process.
Strict Raw Material Sourcing: Inspection of optical fibers, FRP rods, and polyethylene compounds before production.
Global Telecom Supply Experience: Standardized factory processes aligned with international tender requirements.

FAQ
Q: What determines whether to choose HDPE or AT sheath for outdoor installation?
A: HDPE is the standard material for underground duct and general outdoor installations due to its high moisture and UV resistance. An Anti-Tracking (AT) jacket is specified when the cable is installed near high-voltage power lines where induced electrical tracking could degrade standard polyethylene over time.
Q: How are custom cable lengths determined for duct installation projects?
A: Custom reel lengths (such as 2 km or 4 km per drum) are produced based on your specific manhole-to-manhole distances. Providing exact span requirements before production eliminates unnecessary mid-span splicing, accelerates field deployment speed, and preserves optical link performance across your network.
Q: How do you ensure the cable is not damaged during long-distance shipping?
A: All export drums are sealed with waterproof protective wrap and secured with external wooden battens. End caps are applied to both cable ends to prevent water ingress during transport, and drums are secured inside shipping containers using heavy-duty strapping to prevent shifting.
Q: Can we request optical test reports prior to shipment?
A: Yes. Every drum shipped includes a factory test certificate containing optical attenuation data measured by OTDR for every individual fiber core, along with mechanical test validation.
Q: What information is needed to receive a formal quotation for an upcoming project?
A: To provide an accurate quote within 24 hours, please share: total required quantity (in kilometers), fiber count (e.g., 24 core), fiber mode/type (e.g., G.652D), sheath material preference, preferred reel length per drum, and target destination port.
