Revolutionizing the Field with the Most Reliable Optical Fiber Connector

The world requires optical fiber communication infrastructure.
The availability of high-speed and stable internet allows people to access the future.

It contributes to a country's development, helps solve various social issues, and provides initiatives for tackling environmental challenges, which leads to the creation of a sustainable future from a variety of angles.
The Lynx-CustomFit™ Splice-On Connector is one device helping to illuminate this future.
The development of optical fiber communication infrastructure is supported by the efforts of workers in the field. That is why we want to contribute even more to the on-site connecting of optical fiber communication infrastructure.
Thoroughly designed from the perspective of workers in the field and crafted with meticulous attention to detail, our Japanese quality optical connectors are the ultimate partner for workers on-site, and we are now delivering them worldwide.
They achieve work with higher quality, efficiency, and simplicity for everyone, and reduce time, costs, and environmental impact, thereby bringing a revolution to business.
This is the Lynx-CustomFit™ Splice-On Connector.
In our pursuit of unleashing the true potential of optical fiber connectors, there is no compromise or end goal.

Efficiency and eco-friendliness realized simultaneously.

With Lynx-CustomFit™, no special training is required before operation. Even first-time users can harness its performance instantly, leading to a reduction in man-hours and labor costs. There is no need for prior surveys either. Operation is simple and efficient, saving the user time.
Lynx-CustomFit™ enables cable management without requiring excess length and eliminates the need to stock various types of connectors in large quantities. Naturally, this leads to reduced transportation costs as well as CO2 emissions during transport. Due to its durability, there is also less need for frequent on-site repairs. Choosing Lynx-CustomFit™ not only increases operational efficiency but also contributes to environmental sustainability. We approach product development from the broadest perspective, aiming to address multiple challenges and explore what is possible.
