GCYFY – Stranded Loose Tube Air Blown Cable
- Air-blown technology reduces labor and time
- Stranded loose tubes protect fibers from stress and moisture
- Optimized for blowing into microducts with minimal friction
- Supports various fiber configurations for future expansion
- Ensures stable signal transmission in harsh environments
The GCYFY Stranded Loose Tube Air Blown Cable is a high-performance fiber optic cable designed for efficient installation using air-blown techniques. Its stranded loose tube structure provides superior protection for optical fibers while ensuring flexibility and ease of deployment in microducts. Ideal for FTTH (Fiber-to-the-Home), telecom networks, and data centers, this cable offers excellent mechanical and environmental resistance.
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
