Ultra-High-Fiber-Count Optical Cable for Data Center Applications

摘要

This paper describes a newly designed ultra-high-fiber-count (UHFC) optical fiber cable for data center applications. The UHFC cable employs Freeform Ribbon, in which fibers meet and split out in turns in a longitudinal and transverse direction, thus allowing high fiber density and mass fusion splicing. Having a non-preferential bend axis, the cable can easily be installed in space-constrained areas. We combined the Freeform Ribbon technology with a new cable design to significantly increase fiber density compared to conventional underground cables while retaining their advantageous features such as easy handling, identification,and mass fusion splicing.
