Fujikura Launches 100R Mass Fusion Splicer for High-Density Fiber Deployments

In April 2026, Fujikura Ltd. will begin sales of its 100R mass fusion splicer for high-density fiber deployments in data centers and next-generation communication infrastructure. 

As fiber counts increase and cable designs move toward smaller diameters and higher density, the 100R is designed to improve slicing speed and efficiency. The splicer supports both single fibers and intermittently bonded ribbon fibers (SWR) with a max of 16 fibers per splice.

New features of Fujikura’s 100R mass fusion splicer

The 100R introduces an automatic optical fiber seating function, which corrects misaligned fibers in the V-groove, minimizing the need to reset fibers. The splicer also features a fiber end gap correction function that equalizes the gap between fiber end faces prior to fusion splicing to reduce connection loss.

Fujikura’s new splicers also include its FH-80 series fiber holder featuring a clamp mechanism enhancing fiber setting performance with intermittently bonded ribbon fibers. The fiber holders and V-grooves are interchangeable to support various fiber counts and configurations.

A built-in Splice Coach function provides step-by-step guidance that can help “even inexperienced users” through the process. With the GPS function, splice results are logged with the connection position information to support construction tracking. That data can be downloaded to a smartphone with Fujikura’s Splice+ mobile app.

Conventional features

The 100R also incorporates existing features like automated windscreen operation, active fusion control technology that controls discharge conditions, and wireless blade management to support consistent, low-loss connections.
