Description:
GYFXTY is a non-metallic central tube type outdoor optical fiber cable widely used in communication networks. It is designed to adapt to complex outdoor environments (such as direct burial, aerial, or duct installation) while avoiding the use of metal components, making it suitable for scenarios with strict requirements for electromagnetic interference (EMI) resistance and lightning protection. It is a common choice for access networks, rural communications, and short-distance backbone transmission.
Model Definition:
GYFXTY belongs to the "GY" series of outdoor optical fiber cables (the national standard prefix for outdoor communication optical cables in China, equivalent to international outdoor cable classifications). The suffix "FXTY" defines its structural features:
F: Represents non-metallic reinforcement FRP (Glass Fiber Reinforced Plastic, avoiding electromagnetic interference and corrosion risks).
X: Indicates a central tube structure (the optical fiber is placed in a single central loose tube).
T: Refers to the loose tube filled with tube gel which protects well the fiber from external moisture and stress.
Y: Denotes a polyethylene (PE) outer sheath (provides secondary protection against outdoor environmental damage).
GYFXTY Fiber Optic Cable is a lightweight, non-metallic, and cost-effective outdoor cable, typically used for short to medium-distance transmission and is compatible with both single-mode (SM) and multi-mode (MM) optical fibers.
The 2-24 fibers are positioned in a central loose tube and filled with tube gel. Then 2 non-metallic parallel FRP applied around the tube as strength member. The cable is protected by a layer of polyethylene (PE) sheath, which provides good mechanical protection and environmental resistance. This type of cable is suitable for various laying methods, such as overhead, buried, and duct laying.
| Layer | Composition | Function |
| 1. Optical Fiber | Single-mode (e.g., G.652D, G.657A1) or Multi-mode (e.g., OM3, OM4) fibers | Transmit optical signals |
| 2. Central Loose Tube | PBT (Polybutylene terephthalate) | Encloses and protects optical fibers; filled with water-blocking gel to prevent moisture intrusion and buffer fiber micro-bending. |
| 3. Non-Metallic Reinforcement | glass fiber reinforced plastic (FRP) | Provides mechanical strength (tensile, compressive, and bending resistance) without metal components (avoids lightning strikes and EMI). |
| 4. Outer Sheath | UV-resistant PE or LSZH PE | The outermost protective layer; resists UV radiation, aging, and mechanical impact. |

GYFXTY Structure Diagram
No metal wires or tapes, so it is immune to electromagnetic interference (EMI) and radio frequency interference (RFI)—suitable for areas near power lines, substations, or industrial equipment.
Avoids corrosion caused by metal oxidation (critical for humid or coastal areas) and eliminates the risk of lightning-induced damage (a major issue for metallic cables in outdoor environments).
UV resistance: The outer PE sheath is modified with UV stabilizers, ensuring long-term use (≥20 years) in direct sunlight without aging or cracking.
Waterproof and moisture-proof: The central tube is filled with water-blocking gel, and the sheath layer has low water vapor permeability—prevents fiber attenuation caused by moisture.
Wide temperature range: Operates stably in temperatures from -40°C to +70°C, adapting to cold northern regions and hot southern climates.
Tensile strength: Supported by aramid yarns or FRP, it can withstand short-term tensile forces of 600–1000N (sufficient for overhead or buried installation).
Bending performance: The central tube structure and flexible sheaths allow a minimum bending radius of 10× cable outer diameter (static) and 20× cable outer diameter (dynamic), facilitating installation in narrow spaces.
Compared to metallic central tube cables (e.g., GYXTW), GYFXTY is 20–30% lighter, reducing labor and equipment costs for overhead or aerial installation.
No need for grounding (unlike metallic cables), simplifying on-site construction and shortening project cycles.
Simple structure (fewer layers than armored cables) and non-metallic materials lower production costs, making it ideal for large-scale deployment in access networks (e.g., "last-mile" connections to villages or communities).
Applications:
Deployed as FTTH (Fiber-to-the-Home) distribution cables—connecting central offices (CO) to residential buildings or rural access points.
Used in FTTB (Fiber-to-the-Building) networks to transmit signals from street cabinets to building basements.
Ideal for rural "broadband coverage" projects: Its non-metallic design avoids lightning damage (common in rural open areas), and its low cost fits budget constraints for large-area deployment.
Widely used as aerial cables (hung on utility poles) in areas where buried installation is difficult (e.g., mountainous regions, riversides). Its lightweight and tensile strength ensure stable operation under wind loads.
Applied in industrial parks or power plant auxiliary networks: Resists EMI from industrial equipment and power lines, ensuring reliable signal transmission for monitoring or control systems.
Used in coastal areas or humid regions: Non-metallic materials prevent corrosion from salt spray or moisture, extending cable service life.
Used in temporary networks (e.g., construction sites, disaster relief) due to its easy installation and low maintenance requirements.
