All dry-type ribbon optical cable and method of making the same

Abstract

The present invention describes an all dry-type ribbon optical cable and its manufacturing method. The ribbon optical fibers are wrapped using a loose tube, with the tube closely surrounding the fibers as much as possible to increase the fiber-to-space ratio, thereby enhancing the structural cost-efficiency. Additionally, dry-type water-blocking materials are used both inside and outside the loose tube, eliminating the use of grease. This environmentally friendly design improves the fiber-to-space ratio within the loose tube while significantly enhancing the ease of installation. The sheath is designed with air-guiding grooves, enabling air-blown installation of the optical cable. This reduces labor requirements, speeds up installation, and minimizes attenuation caused during deployment. During the manufacturing process, the ribbon optical fibers and the first dry type water-blocking components enter the loose tube in a wavy pattern during extrusion.
