Testimonials
The build quality surprised me. It feels like a €2,000+ device. The heat-free crimp system is a game-changer for outdoor installations.
Finally, a fusion splicer tailored to German infrastructure. Six-motor alignment is rock-solid, and the battery life lasts all day in the field.
Splice losses consistently below 0.02 dB. My acceptance tests have never been this clean. The AI-9 pays for itself through saved callbacks.
First, we tried the competition. The AI-9 beats them in speed, accuracy, and price. This is now our standard fusion splicer.
The transport case is truly field-ready. After six months of rough handling, the device still calibrates perfectly every time.
