2pc Fiber Optic Visual Fault Locator VFL Fiber Optic Cable Tester with 2pcs Singlemode 9/125um FC Male to LC Female Adapter, Red Switch (Mode Number: VFL-50)

Works as it should.

Use this for work. And is works great had it on a 12 mile stretch of fiber, made it easy to find the break.

All my coworkers are jealous. The extra power shows most failure modes and losses, including too tight radius curves.

These things are bright! You can fault locate an issue with fiber cable even in direct sunlight with no problem. This has made my job so much easier. It was worth the $30 to not have to cover a cable to see my company provided vfl flashing under a black tarp. Awesome!!!!

The tool works well. The adapter provided is not the correct one. It does not attach to the light source.

Great product the only con i have is that the off position is in the middle and sometimes it gets put on by accident

Opened package, put batteries in device, turned it on and the laser did not come on. The indicator light on the switch came on for continuous and for glint mode but neither mode produced the test light. Replaced batteries and same result. 3 stars due to frustration. Will be sending it back to get it repaired or replaced. My review will be 1 star if they give me the runaround or 5 stars if its replaced/repaired.

Extremely, extremely! Bright laser! Batteries last long and can trace individual strands with ease (minimal microbend)
