Description
Central Bundle Tube Type Non-metallic Non-armored Optical Cable exhibits good mechanical performance and temperature characteristics. The colored optical fibers are encased in loose tubes made of high-modulus, hydrolysis-resistant material, filled with thixotropic water-blocking gel for superior moisture protection. To ensure full longitudinal water resistance, water-blocking material is applied around the loose tubes. Two parallel glass fiber-reinforced plastic (FRP) rods provide additional strength and stability. The entire assembly is then encased in a durable polyethylene sheath, delivering excellent mechanical performance and environmental resistance.

- Reinforced Tensile Strength with Dual FRP Rods
Two parallel FRP (Fiber Reinforced Plastic) rods improve cable stability and tensile performance.
- Compact and Lightweight Design
Small diameter and low weight facilitate easy installation and handling, even for long-distance deployments.
Application Scenario
With its lightweight, non-metallic design and excellent resistance to electromagnetic interference, GYFXY cable is an economical and efficient choice for outdoor optical communication networks, particularly in duct installations, low-stress aerial applications, and EMI-sensitive areas.
- Duct Installation
GYFXY cable is ideal for duct installations, ensuring easy deployment and immunity to electromagnetic interference.
- Aerial Installation
With proper support measures, it can be used as an aerial cable, adapting to weather conditions such as wind and rain, suitable for areas with low mechanical stress.
- Electromagnetic Interference-Sensitive Areas
The non-metallic structure eliminates electromagnetic interference issues, making it ideal for areas near high-voltage power lines or industrial zones.
- Rural and Urban Communication Networks
Widely used in urban backbone networks and rural communication infrastructure, especially in scenarios where additional mechanical protection is unnecessary.
- Low-Mechanical-Stress Areas
Suitable for regions with minimal mechanical stress, such as flat terrains or areas without heavy machinery activity.
- Environments with High Corrosion or Moisture Levels
Its non-metallic and corrosion-resistant properties make it suitable for humid or corrosive environments, such as coastal areas or near chemical plants.
