Description
The fiber optic 12 core cable is a high-performance indoor distribution cable designed for modern fiber optic communication networks. Built with G.657A1 bend-insensitive optical fibers, this cable provides excellent transmission stability, low attenuation, and strong mechanical reliability, making it ideal for core networks, access networks, and FTTH (Fiber to the Home) deployments.
Fiber optic 12 core cable adopts a loose tube structure with PBT material and thixotropic jelly filling, effectively protecting optical fibers from moisture and mechanical stress. A phosphating steel wire central strength member enhances tensile strength and durability during installation, while the LSZH (Low Smoke Zero Halogen) outer sheath ensures safety and environmental protection in indoor environments.
With clear fiber color coding for easy identification, stable performance under varying temperatures, and excellent resistance to bending, crushing, and tension, this 12 fiber optic cable offers a reliable and efficient solution for high-speed optical network infrastructure.
Fiber optic 12 core cable Features
- Robust Outdoor Protection: The cable features a steel armored construction and waterproof sheath, making it resistant to moisture, UV radiation, and temperature variations for reliable outdoor use.
- 12 Color-Coded Fibers: Each of the 12 fibers is distinctly color-coded with non-fade colors, ensuring accurate identification and splicing during installation and maintenance.
- Permanent Length Marking: The sheath is marked at 1-meter intervals with fiber type, quantity, manufacturer details, and manufacturing date. These marks are permanent and legible for the cable’s entire lifespan.
- Versatile Application: Perfectly suited for core networks, access networks, and Fiber to the Home (FTTH) installations, supporting high-speed data transfer for modern broadband needs.
- High Bandwidth Support: Engineered to support high-performance networks, with verified capability for 10G fiber applications, ensuring your infrastructure is ready for future speed demands.
- Secure Packaging & Custom Lengths: Delivered on drums with protected ends to prevent damage during transit. Available in standard 1km lengths or customizable according to project requirements.
Fiber color code
Color-coding of the fiber will be clear, and not fade under the influence of the temperature of working and installation environment.
