GCYFXTY
Uni-tube Air-Blown Micro Optical Fiber Cable For FTTx Network
Power system Lighting-prone areas
■ Product Overview:
The cable structure consists of optical fibers housed in a high-modulus plastic loose tube filled with tube-filling compound. Aramid yarn reinforcement is applied outside the loose tube, followed by an extruded grooved sheath. This cable is specifically designed for air-blowing installations in access networks.
■ Key Features:
- Compact size and lightweight: Facilitates easy deployment.
- Tube filling compound: Provides critical fiber protection.
- Grooved sheath design: Enhances air-blowing efficiency.
- Phased blowing installation: Reduces initial investment costs.
- High-speed blowing (up to 50 m/min) and long-distance blowing (up to 1,000 m).
- Replaceable design: Allows cable removal and replacement for future upgrades.
- On-demand branching: Enables micro-duct cutting at any point without disrupting existing cables, minimizing manholes and splice points.
