How Much You Know Anout Duct Fiber Optic Cables (Duct FO Cable)?
Duct Fiber Optic Cables are designed for installation in underground ducts or conduits. They are ideal for long-distance communication, backbone networks, and other outdoor installations. These cables come in various types, including GYTA, GYTS, GYTY, GYFTY, GYFTA, and GYXTW, each tailored for specific environmental conditions and applications.
1. Common Features of Duct Fiber Optic Cables
Durability: Designed to withstand harsh outdoor conditions such as temperature fluctuations, moisture, and mechanical stress.
Water and Rodent Resistance: Many duct cables include water-blocking materials and anti-rodent features to ensure reliability.
High Capacity: Support multiple optical fibers, enabling high data transmission rates for telecommunications networks.
2. Types of Duct Fiber Optic Cables
(1) GYTA: Stranded Loose Tube, Aluminum Tape Armored
Structure: Loose tube with aluminum tape for additional protection.
Application: Ideal for areas with moderate mechanical stress and rodent activity.
Features:
Water-blocking gel-filled tubes.
Aluminum tape armoring provides anti-moisture protection.
High tensile strength for duct installations.
(2) GYTS: Stranded Loose Tube, Steel Tape Armored
Structure: Loose tube with steel tape armoring.
Application: Suitable for areas with high mechanical stress or rodent activity.
Features:
Steel tape for enhanced mechanical strength.
Water-blocking system to prevent water ingress.
Commonly used in underground ducts.
(3) GYTY: Stranded Loose Tube, PE Jacket
Structure: Loose tube design with a polyethylene (PE) outer jacket.
Application: Primarily used in areas with low mechanical stress or no rodent activity.
Features:
Lightweight and cost-effective.
Resistant to environmental corrosion.
Good for straight duct installations.
(4) GYFTY: Non-Metallic Strength Member, PE Jacket
Structure: Loose tube with glass yarn (non-metallic strength member) and a PE jacket.
Application: Ideal for areas with high electromagnetic interference (EMI).
Features:
All-dielectric design avoids grounding issues.
Resistant to EMI, making it suitable for power line areas.
Lightweight and easy to install.
(5) GYFTA: Non-Metallic Strength Member, Aluminum Tape Armored
Structure: Loose tube with aluminum tape armoring and a non-metallic strength member.
Application: Suitable for areas with moderate EMI and mechanical stress.
Features:
Combines EMI resistance with moisture protection.
Water-blocking technology enhances durability.
Aluminum armoring improves rodent resistance.
(6) GYXTW: Central Loose Tube, Steel Wire Strength Members
Structure: Central loose tube surrounded by steel wire for reinforcement.
Application: Suitable for long spans and high tensile strength requirements.
Features:
Compact design for high fiber density.
Steel wire improves tensile strength.
Excellent performance in duct installations requiring longer pulling distances.
3. Comparison of Duct Fiber Cable Types
| Cable Type | Armoring | Strength Member | Application | Key Feature |
| GYTA | Aluminum Tape | Central Strength Member | Moderate mechanical stress | Moisture and rodent resistance |
| GYTS | Steel Tape | Central Strength Member | High mechanical stress | High tensile and crush resistance |
| GYTY | None | Central Strength Member | Low mechanical stress | Lightweight and cost-effective |
| GYFTY | None (Dielectric) | Non-Metallic (Glass Yarn) | High EMI areas | EMI-resistant, non-conductive |
| GYFTA | Aluminum Tape | Non-Metallic (Glass Yarn) | Moderate EMI and stress | Combines EMI resistance and durability |
| GYXTW | None | Steel Wire | Long spans, high tension | High tensile strength and compact |
4. Key Considerations for Selection
Mechanical Stress:
For high-stress environments, choose GYTS or GYXTW for enhanced strength.
Environmental Factors:
For areas prone to moisture, GYTA or GYFTA with aluminum tape armoring is suitable.
Electromagnetic Interference (EMI):
For high-EMI areas, use dielectric cables like GYFTY or GYFTA.
Installation Distance:
For long pulling distances, GYXTW provides excellent tensile strength.
5. Applications of Duct Fiber Optic Cables
Telecommunications Networks: Backbone connections, metro networks, and FTTH deployments.
Power Grid Communication: Especially with EMI-resistant options like GYFTY.
Industrial Installations: Robust cables like GYTS and GYTA are used in demanding environments.
Long-Distance Transmission: High tensile strength cables like GYXTW.
Duct fiber optic cables, including GYTA, GYTS, GYTY, GYFTY, GYFTA, and GYXTW, offer versatile solutions tailored to diverse environments. Selecting the right type depends on factors like mechanical stress, electromagnetic interference, and environmental conditions. These cables are integral to building robust and efficient communication networks, ensuring reliable data transmission over long distances.
