INFORMATION
The GCYFY Stranded Loose Tube Air Blown Fiber Optic Cable is a Micro Fiber Optical Cable designed for efficient and reliable long-distance data transmission. The air blown fiber is easy to install and has excellent environmental performance. Stranded air blown fiber optic cable consists of a central loose tube containing multiple strands of optical fiber surrounded by a protective outer sheath. The Stranded Air blown Cable features a miniature design that allows it to be blown to designated locations using air pressure, reducing installation costs.
The Stranded Air blown Fiber Optic Cable is an efficient, convenient and cost-effective cable solution. It uses FRP as reinforcement, is lightweight and has a small diameter.
