Why Choose Sumitomo Electric ?

The Reason
Customers Choose Us.

Performance made simple. Precision made tough.
Sumitomo Electric’s exceptional technology has seamlessly integrated all these seemingly divergent elements.
Our fusion splicers’ superior performance
was born from our steadfast focus on the future, while their ease-of-use resulted from
careful inquiry into our customers’ needs.
Our splicers’ precision lies in the passion of our engineers,
while their durability and toughness derive from a long history of technical achievements.
What’s more, to ensure the best splicing experience anywhere on the globe,
our production staff stand committed to quality day in and day out.
These are the reasons customers choose Sumitomo Electric.
Each and every one of our products continues to inherit the DNA that makes us who we are.

High-SpecLineReason #1

The Ultimate in

We pushed the limits of performance in our microscopes so that they can instantly assess any fiber optic cable laid anywhere around the world.
Our fusion splicers achieve the highest level of reduction in splicing loss without relying on advanced skills or training.
In addition, our original IoT technology SumiCloud™ lets users connect to Sumitomo Electric's cloud services via smartphone, thereby supporting the timely sharing of information between office and worksite, while also contributing to device management and maintenance.
At Sumitomo Electric, our fusion splicers never stop evolving.


Easy OperationLineReason #2

No More Mistakes

NanoTune™ is the world’s first AI splicing technology.
Up until now, operators struggled to recut the defective ends of fiber optic cables.
Now, the fusion splicer itself takes care of everything despite any defective ends.
At Sumitomo Electric, we’ve improved splicing success rates from 75% to over 90%, delivering the ultimate in high-spec performance.
We also were the first in the world to mount a touch panel directly on our fusion splicers, and we continue to improve upon our graphical user interfaces to this day.
This means that, much like a smartphone, our devices can be operated intuitively by anyone who handles them.
We’ve worked to pack everything into a compact body, while aiming to create a fusion splicer that can be used anywhere by anyone.
