Rollable Ribbon technology

Imagine a technology leap that doubles a cable’s fiber optic density while reducing the size of that same cable. Furukawa Electric Rollable Ribbon high density optical fiber cable are delivering that advance today. Furukawa Electric Rollable Ribbon Cables have the smallest diameter and highest core density *. At the same time, these cables allow installers to double the density of vital pathways versus standard cable designs. This makes Rollable Ribbon fiber cables an ideal choice for indoor and outdoor use, connecting data centers, or serving as the distribution for dense FTTx and mobility networks.

We create these Rollable Ribbons by partially bonding single 200 µm fibers or 250 µm fibers to each other to form a flexible cable. This design allows for a highly efficient ribbon splicing and easy single or multiple fiber breakout. These completely gel-free cable designs also help to reduce the time required for splicing preparation.

Above all, doubling the density of your fiber means doubling your transmission capacity, doubling your capability, and doubling your ability to get the job done.
