GYFTY is an all-dielectric, non-metallic loose tube fiber optic cable engineered for outdoor duct and aerial communication networks. Built with a central FRP strength member and a UV-resistant HDPE outer jacket, it completely eliminates electromagnetic interference, making it ideal for high-voltage power lines, lightning-prone areas, and FTTH backbone infrastructure.
Key Product Features
100% Non-Metallic Structure: Electromagnetic interference (EMI) immune and lightning-resistant, eliminating grounding requirements and risk of induced current.
Water-Blocked Core: Gel-filled loose tubes combined with full-cable water-blocking compound ensure long-term moisture barrier and axial water ingress protection.
Weather & UV-Resistant HDPE Outer Sheath: Formulated for high mechanical toughness, abrasion resistance, and long-term stability under continuous outdoor UV exposure.
Low Attenuation Transmission: Supports standard G.652D, bend-insensitive G.657A, and high-speed multimode fibers to guarantee minimal optical loss over extended network distances.
Customization & OEM Capabilities
Fiber Options: Corning, YOFC, FiberHome, or client-specified brands.
Outer Sheath: Standard HDPE (Black) or Flame-Retardant LSZH (Custom colors available).
Branding & Marking: Custom meter-markings, company logo, and cable coding printed per meter.
Packaging: Export-standard fumigated wooden drums (1km, 2km, 3km, or 4km ±5% lengths).
Customization Workflow
Requirement Specification: Define fiber count, fiber brand (Corning/YOFC), jacket material (HDPE/LSZH), and delivery length.
Technical Approval: Review and sign off on technical drawings, sheath marking text, and color coding schemes.
Sample & Production Approval: Pre-production sample testing or direct batch production upon technical sign-off.
Batch Manufacturing & QC: Continuous inline inspection (SZ-stranding, tube filling, sheath extrusion) and jacket optical check.
Custom Packaging & Dispatch: Export-grade wooden drum packaging with custom shipping marks and FAT report attachment.
Manufacturing & Quality Control
Optical Test
Attenuation mapping at 1310nm / 1550nm via OTDR.
Mechanical Test
Tensile strength, repeated bending, and crush resistance testing.
Environmental Test
Water penetration test (24h) and temperature cycling (-40°C to +70°C).
Target Applications
High-voltage power line proximity routes (Anti-lightning & Anti-EMI)
Duct installations in underground conduit systems
FTTH & Metropolitan Area Network (MAN) backbones
Railway and smart grid communications

FAQ
Q: Is GYFTY suitable for direct burial installation?
A: No. GYFTY lacks metallic armor. For direct burial, specified armored cables like GYTA53 or GYTS53 are required to prevent rodent and crush damage.
Q: What test reports are shipped with the order?
A: Each drum comes with an individual Factory Acceptance Test (FAT) report, including OTDR attenuation data, dimensional checks, and fiber trace records.
Q: Can you supply pre-terminated or custom-length reels?
A: Yes. Standard reels are 2,000m or 3,000m, but custom lengths from 1,000m to 6,000m can be spooled according to field deployment requirements.
Q: How does the all-dielectric structure benefit high-voltage environments?
A: Because GYFTY contains zero metal components, it does not conduct electricity or attract lightning, preventing induced current hazards near high-voltage lines.
Q: What fiber optic brands do you integrate into GYFTY cables?
A: We standardly integrate G.652D fiber from YOFC or Corning. Client-specified fiber suppliers can be accommodated for large-scale OEM projects.
Q: What is the typical lead time for a 100km GYFTY order?
A: Standard configuration orders of 100km are typically ready for export dispatch within 7 to 10 business days after sample/drawing approval.
Q: Do you support third-party factory inspection before loading?
A: Yes. We welcome third-party inspection agencies (such as SGS, Intertek, or BV) to conduct pre-shipment inspections and drum sampling at our facility.
