Visible Fault Identifier

Yamasaki Compact Visible Fault Identifier

The Yamasaki TVFI Visible Fault Identifier is a practical palm sized solution for finding breaks, bends and faulty connectors or splices in fibre optic cable.

It works by shining an extremely bright 1mW Class 2 laser through any fiber optic cable, causing all cracks, splits or leaks to glow a brilliant bright red. The laser can also be made to flash quickly (Modulate) to aid in fiber optic fault location.
