50km Visual Fault Locator with 50mW Fiber Optic Source Light Tester and Red Light Pen -Compatible with FC/SC/ST/LC adapters - Ideal for CATV Telecommunications - Fiber Network Cable Testing

Works good and easy. Battery doesn’t last that long and connector tip falls off easy

I haven't had a chance to use it yet since I received it before the holiday. I did however test a few of my patch cables and a network card and it worked great up close. I'll be testing a 1K foot run next week with it.

Works great. Has come in handy several times locating faults and tracing fiber. My company didn’t provide one for me and if they would have it would have cost ALOT more than this one. Gets the job done.

Works fine with a bright light at the far end of a 25 meter fiber. The only issue is that the switch has weak detentes, and needs to be wiggled a bit to get it to stay on.

I will say that the light is very strong, lets see in a month how it hold the power. and how long the light keep on after switch to on.... I will update

Works great for my line of work. Very happy with thus product.

If I had one critique, the batteries die fast. But we love it.

company issued us 1mv ruby lights that was hard to find your light. This one shows every defect in the fiber and has been working great.

I am happy with purchase

I am doing professional work more than 15 years and the last 8 years on fiber optics. I have work with numerous lasers and I have seen good and bad ones. This one definitely is not good. It advertised as 30KM, well with only one splice between it strangle to get 1KM at the best.It can be a faulty one, I don't know but this one I got is terrible. My opinion as professional is , DO NOT BUY.

Justo lo que pedi es lo que me llego trabaja muy bien cumple con su funcion

The added adapter is so helpful when in the field & different connectors are in use, used on a 15k with no issues with light strength, use quality batteries for best results & longer use times

The distance and brightness of the device is great
