Unitube Armored Outdoor Cable GYXTW

The GYXTW armored fiber optic cable is a lightweight outdoor cable designed for reliable performance in access networks, aerial installations, and duct deployments. Featuring a central loose tube structure with steel tape armor, it provides excellent mechanical protection against crushing, moisture, and environmental stress.

This cable is widely used in FTTH, telecom distribution networks, and last-mile connectivity projects.

What Is GYXTW Fiber Optic Cable?

GYXTW is a unitube (central loose tube) armored fiber optic cable designed for outdoor communication applications. The structure includes:

• Central loose tube with optical fibers
• Water-blocking gel filling
• Corrugated steel tape armor
• Two parallel steel wires for tensile strength
• PE outer sheath for weather resistance

👉 It is optimized for outdoor durability and cost-effective deployment

GYXTW Cable Structure Explained

Understanding the structure helps engineers choose the right cable:

🔹 Central Loose Tube Design

• Fibers are placed in a single tube
• Reduces cable diameter and weight
• Improves installation efficiency

🔹 Steel Tape Armor (PSP)

• Protects against crushing and rodent damage
• Acts as moisture barrier

🔹 Dual Steel Wire Strength Members

• Provides high tensile strength
• Suitable for aerial installations

🔹 PE Outer Jacket

• UV-resistant and weatherproof
• Ensures long-term outdoor reliability

Key Features

• Lightweight armored design for easy installation
• High tensile strength for aerial deployment
• Excellent crush resistance and mechanical protection
• Full water-blocking structure for moisture resistance
• Suitable for duct, aerial, and direct-buried applications
• Available in 2–24 fiber cores

Where GYXTW Cable Is Used

GYXTW cables are widely used in:

✔ FTTH Access Networks

• Feeder and distribution segments
• Last-mile fiber deployment

✔ Aerial Installation

• Pole-to-pole connections
• Rural and suburban networks

✔ Duct Installation

• Underground conduits
• Urban fiber infrastructure

✔ Campus & Industrial Networks

• Inter-building connections
• Outdoor backbone links

👉 Ideal for access-level and distribution network scenarios

GYXTW vs Other Outdoor Fiber Cables

🔹 GYXTW vs ADSS

• GYXTW → armored, suitable for duct/aerial
• ADSS → non-metallic, used on power lines

🔹 GYXTW vs GYTA/GYTS

• GYXTW → lighter, smaller capacity
• GYTA/GYTS → higher fiber count, heavier structure

👉 GYXTW is best for small-to-medium capacity outdoor networks
