GCYFXTY – Central Loose Tube Micro Air Blown Cable
- Designed for air-blown deployment, reducing labor and time
- Compact design allows for more fibers in smaller ducts
- Central loose tube structure safeguards fibers from moisture and mechanical stress
- Optimized for microduct installation with minimal friction
- Suitable for 5/3.5mm or larger microducts
The Central Loose Tube Micro Air Blown Cable is an advanced fiber optic cable designed for efficient and flexible installation using air-blown techniques. It features a central loose tube structure that protects optical fibers while allowing for easy blowing into microducts. This cable is ideal for high-density fiber deployments in FTTH (Fiber-to-the-Home), data centers, and telecommunication networks, ensuring high performance and reliability.
FEATURES:
- Small size and light weight
- Tube filling compound providing key protection for fibers
- Unique design of sheath with grooves ensuring good air blowing performance
- Allowing to blow by phases to reduce initial investment
- High blowing speed up to 50m/min, and long blowing distance up to 1000m
- Allowing to blow out and replace with new cables to keep technical superiority
- Allowing to cut micro ducts anywhere anytime for branch without influences on other cables, saving manholes, hand holes and cable joints
