Uni-tube Non-metallic Non-armored Fiber Optic Cable

The core architecture of the Uni-tube Non-metallic Non-armored Fiber Optic Cable (GYFXY) utilizes a central loose tube design. Within this high-modulus tube, 250μm optical fibers are protected by a specialized waterproof compound. To maintain structural integrity without the use of metal, two parallel Glass Fiber Reinforced Plastics (FRP) are positioned on opposite sides of the tube. This configuration is then encased in a robust Polyethylene (PE) sheath, providing a balance of flexibility and tensile strength.

Core Specifications and Material Composition

• Optical Fiber: Standard 250μm fibers housed in a protective loose tube.
• Strength Members: Dual parallel FRP (non-metallic) for electromagnetic interference (EMI) resistance.
• Water Blocking: Integrated water-blocking materials and tube-filling compound to prevent moisture ingress.
• Outer Protection: UV-resistant PE sheath suitable for diverse environmental conditions.
• Compliance: Fully compliant with YD/T 769 standards for telecommunications.

Operational Advantages for Network Infrastructure

1. Non-Metallic Design for Interference-Free Transmission

Since the Uni-tube Non-metallic Non-armored Fiber Optic Cable uses FRP instead of steel, it is completely dielectric. This is a critical value point for engineering projects near power lines or in regions prone to lightning, as it eliminates the risk of induced current.

2. Streamlined Installation and Handling

The small diameter and reduced weight of the Orientalfiber GYFXY cable allow for longer delivery lengths and easier pulling through narrow ducts. This reduces the number of necessary splices, lowering both labor costs and signal attenuation.

3. Environmental Resilience

The PE sheath and hydrolysis-resistant loose tube materials ensure the Uni-tube Non-metallic Non-armored Fiber Optic Cable remains functional under varying temperatures and UV exposure. The internal ointment provides a secondary buffer, protecting the fibers from physical stress and moisture.

Procurement and Application Context

For wholesale buyers and project managers, the Uni-tube Non-metallic Non-armored Fiber Optic Cable represents a cost-effective solution for local area networks (LAN), highway monitoring systems, and rail transit communication. Orientalfiber provides a complete supply chain—from the indoor/outdoor cable factories to ODN components—ensuring that the cable integrates seamlessly with existing network equipment.

Common Procurement Inquiries (FAQ)

What is the primary benefit of the GYFXY structure? 

The GYFXY structure is specifically designed for environments where lightweight and non-conductive materials are required. It simplifies aerial or duct installation while providing sufficient tensile strength through the parallel FRP.

How does Orientalfiber ensure quality across large-scale orders? 

As a group company with an annual output of 20 million USD, we implement ISO9001 and ISO45001 standards across all four of our specialized factories. Every batch of Uni-tube Non-metallic Non-armored Fiber Optic Cable undergoes testing for tensile strength, crush resistance, and water penetration.

Can this cable be used in industrial front-end connections? 

Yes. Our cables are widely utilized in electrical power systems and industrial automation where EMI protection is mandatory.
