Ultra-High-Fiber-Count and High-Density Slotted Core Cable with Pliable 12-fiber Ribbons

摘要

This paper describes the configuration of a new Ultra-High-Fiber-Count (UHFC) and High-Density (HD) slotted optical fiber cable with 12-fiber-pliable ribbons. We combined the pliable ribbon technology with a slotted core cable design to create the cable that doubles the fiber count while the diameter remains the same as conventional cables. The pliable ribbon consists of fiber adhesive parts and non-adhesive parts coming in turns in a longitudinal and transverse direction, enabling high fiber density within a limited duct space and mass fusion splicing. A slotted core cable is designed with a non-preferential bending axis, allowing for easy installation in space-constrained areas. Its best characteristics, such as easy handling, good identification, and mass fusion splicing, are retained in our new cable. This paper describes the design of the 12-fiber ribbon and the test results of mass fusion splicing. It also refers to the designs and characteristics of 3456-fiber-count slotted core cables, which are the highest-count optical cables in commercial use, and 1728-fiber count slotted core cables.
