Home>Products>Outdoor Optical Cables>Non-Metallic Loose Tube Blown Micro Cable
The GCYFY micro cable structure involves placing single-mode or multimode fibers into loose tubes made of high-modulus polyester material, with the tubes filled with waterproof compound. The cable core centers on a non-metallic strength member (FRP), which for certain fiber counts is additionally coated with an extruded layer of polyethylene (PE). The tubes (and filler rods) are stranded around the central strength member to form a compact circular core, with interstices filled with water-blocking material, and finally extruded with an outer polyethylene jacket to complete the cable.

1. Small diameter, light weight, and moderate stiffness, suitable for blown installation.
2. High fiber density, maximizing duct space utilization.
3. Blowing speed of micro cable reaches 30-70 meters/minute, with a single blowing distance up to 1200 meters, ensuring high installation efficiency.
4. Allows incremental cable deployment as traffic grows, enabling phased investment and reducing initial costs.
5. Micro cables can be blown out for future replacement with advanced fiber types, maintaining technological leadership.
6. Ideal for construction in congested metro duct networks, avoiding destructive excavation and eliminating high costs associated with right-of-way acquisition.
7. Suitable for backbone, metro, and access network applications.
