Outdoor Overhead Duct Optical Cable is a non-metallic, loose-tube optical fiber cable engineered for aerial and duct deployments. Built with a Fiber Reinforced Plastic (FRP) central strength member and a high-density polyethylene (HDPE) outer sheath, it eliminates electromagnetic interference while delivering stable signal transmission across FTTx, telecom backbones, and power utility grids.
Core Engineering Advantages
Immunity to Interference: The 100% non-metallic build prevents lightning strikes and induction current, eliminating the requirement for grounded electrical protection along power lines.
Dual-Environment Protection: UV-stabilized HDPE outer jacket combined with longitudinal water-blocking compound ensures long-term integrity against moisture ingress and outdoor exposure.
Streamlined Inventory: Dual-rated structural design supports both overhead suspension and underground duct pulling, reducing SKU variety for large-scale network rollouts.
Applications
FTTx Last-Mile Access & Telecom Backbone Networks
High-Voltage Power Utility Transmission Lines (Proximity Installations)
Railway, Highway, and Smart City Security Infrastructure
Campus and Metropolitan Area Networks (MAN)
Customization & OEM Capabilities
Branding & Cable Marking: OEM outer jacket printing including company logo, part numbers, and custom sequential meter/foot markings.
Jacket & Material Options: Flame-retardant (LSZH), anti-rodent, or track-resistant outer sheath formulations for specialized installation environments.
Packaging & Spool Options: Custom reel sizing on export-grade fumigated wooden, steel-wooden, or iron drums to fit project transportation limits.
Manufacturing Precision & Quality Assurance
SZ-Stranding Process: Controlled excess fiber length (EFL) management guarantees zero micro-bending stress during tension and thermal expansion.
Material Integrity: Formulated with high-grade HDPE and raw virgin optical fibers to guarantee a 25+ year outdoor service life.
Factory Acceptance Testing (FAT): 100% of production runs undergo OTDR attenuation testing, tensile loading tests (IEC 60794-1-2-E1), crush resistance verification (IEC 60794-1-2-E3), and water penetration tests (IEC 60794-1-2-F5).
Global Supply & Manufacturing Capacity
Production Scale: Modern production facilities with an annual capacity of 15 million core kilometers, built to support large-scale national backbones and major telecom rollouts.
Global Footprint: Proven supply record across North America, Europe, East Asia, and the Middle East, serving Tier-1 telecom operators and national infrastructure contractors.
Compliance & Quality Systems: Operating strictly under ISO 9001 and ISO 14001 certification standards to guarantee batch-to-batch operational reliability.
Export Logistics: Comprehensive support for global trade terms including EXW, FOB, CIF, and DDP with complete documentation (CO, Form E, Packing List, and FAT reports).

FAQ
Q: How does the non-metallic (GYFTY) structure benefit power utility networks?
A: The FRP central member and fully dielectric design completely eliminate electrical conductivity. This prevents electromagnetic induction caused by adjacent high-voltage transmission lines and eliminates the extra material and labor costs associated with grounding protection.
Q: What attenuation levels can be expected from your G.652D fiber cables?
A: Our G.652D single-mode fibers strictly adhere to ITU-T standards, delivering typical attenuation of <= 0.35 dB/km at 1310nm and <= 0.21 dB/km at 1550nm prior to cabling.
Q: What is the standard continuous drum length available for order?
A: Standard supply is 2,000 meters per drum. Custom continuous lengths from 1,000 to 4,000 meters can be supplied based on project routing and reel capacity constraints.
Q: What test documentation is supplied with each delivery batch?
A: Every drum is shipped with an official Factory Acceptance Test (FAT) report detailing OTDR attenuation test curves, drum serial numbers, physical dimensions, and length verification.
Q: Is this cable suited for direct burial underground?
A: No. GYFTY is engineered specifically for aerial suspension and duct pulling. For direct burial applications, we recommend metallic or non-metallic corrugated steel-armored cables (such as GYTA53 or GYFTY53).
Q: What packaging protections are applied for long-distance ocean freight?
A: Cables are wound on fumigated wooden or steel-wooden drums, sealed with thermal moisture barrier film, and fitted with protective end caps to prevent water ingress during transport.
