Outdoor Armored GYXTW G652D Singlemode 6 To 24 Core Fiber Optic Cable
Description
The cable employs high modulus plastic tubes to house the fibers, fortified with a water-resistant compound.
These tubes are enclosed in corrugated steel tape, sealed with water-blocking material to maintain a compact
and waterproof structure. Parallel steel wires reinforce the tape. The cable is completed with a protective poly-
ethylene (PE) sheath, ensuring overall environmental resilience.
Application
This specification outlines fundamental requirements for a Central Loose Tube Outdoor Cable designed speci-
fically for aerial or duct installations.
Characteristics
1 Temperature-Resilient Construction: Ensures consistent performance across diverse environmental temper-
atures, featuring robust mechanical resilience.
2 Fiber Protection: Critical shielding for fibers is provided by a hydrolysis-resistant, high-strength loose tube
and specialized filling compound.
3 Combined Strength and Flexibility: Dual parallel steel wires offer a balance between crush resistance and
flexibility, enhancing tensile strength for long-term reliability.
4 Effortless Installation: Engineered with a compact, lightweight design, ensuring easy and adaptable installations
across various applications for user-friendly deployment.
