Introduction of Loose Tube Air-Blown Micro Cable
The Loose Tube Air-Blown Micro Cable (Model: GCYFY) is designed for efficient deployment in FTTH, Backbone, and Metropolitan Access networks. Built with cutting-edge technology, this cable offers optimum performance that is both fast and cost-effective. It provides outstanding mechanical strength, durability, and exceptionally low friction, making it easy to blow through micro-ducts using air-blowing technology. This product page includes all the technical information, specifications, application guides, and other details that will be helpful to Network Planners, ISPs, and System Integrators looking for reliable and flexible fiber optic cable solutions for their modern fiber network projects.
What is a Loose Tube Air-Blown Micro Cable?
The Loose Tube Air-Blown Micro Cable (GCYFY) contains optical fibers inside a loose tube made from high-modulus plastic, with a special tube-filling compound designed to protect the fibers. Additional support is provided by aramid yarns wrapped around the outside of the tube. The groove design of the outer sheath enhances blowing performance, making the Loose Tube Air-Blown Micro Cable (GCYFY) an excellent choice for phased installations and air-blown deployments.
Key Features of Spring Loose Tube Air-Blown Micro Cable
·Compact and Lightweight Designs
With its reduced diameter, the Loose Tube Air-Blown Micro Cable (GCYFY) reduces friction and allows for longer blowing distances and faster installation through Micro-duct systems.
·High-Density Fibre and Tube-Filled Structure
The tube fill offers moisture resistance and ensures fiber durability. It also helps maintain the optical performance of the fiber, even under mechanical stress.
·Grooved Sheath Design Improves Air Blowing Performance
The grooved sheath design minimizes the contact area of the cable with the duct, significantly reducing friction. This allows for blowing distances of up to 1000 meters.
·Replaceable and Upgradable Construction
The air-blown cable technology enables easy replacement and upgrading of cabling without the need for excavation, making it a cost-effective solution for network expansion.

Additional Benefits:
Flexible Branching Capability
Micro-ducts can be cut at any point, allowing for easier and more cost-effective branching than traditional methods, which often require additional manholes and splice closures.
Micro-Duct Access on Demand
The design allows for micro-duct access on demand, reducing installation time and costs.
