NOYAFA Visual Fault Locator 30mW Network Fiber Cable Red Light Pen Test, Adapt FC/SC/ST Interface Fiber Optic Cable Tester Detector Meter, for 2.5mm Universal Connector (NF-904-30)

Broke on the first use

I like the build of it, makes it durable, I don’t know if I got a loose connection device but it stopped working after only 5 minutes… I’ve tried to troubleshoot it with no luck

I'm. Fiber tech and this doesn't push light from the house to the hub.. not sure why it was bright at first and then the light just doesn't go the distance.

Bad investment

The media could not be loaded.  I use Visual Fault Locators (VFLs) like this one at my work. They are indispensable as far as identifying and locating fiber LAN fiber cables. They can also be used to find breaks in shorter cables and find mismatched cable pairs. This is the first one I have personally owned.Summary:Pros:• Super bright!! Works in brightly lit rooms• Pulse mode allows easier identification in crowded patchbays and fiber boxes• Single and multi-mode cable compatible• Long range• Has a universal 2.5mm output connector• Long battery life >20hrs• Has pulse mode• Low costCons:• May be too strong(see below)• Did not come with an adapter for LC connectorsI presently use another well-known brand VFL at my work. I have made a few side by side comparisons with this other unit and in every test, the Noyafa was much brighter, making it far easier to identify the cable in question. As you can see from the videos and pictures, the Noyafa is simply brighter. This makes it easier to spot breaks and light loss areas, such as tight bends and at the termination points. This is important if one is tracking cables in a well lite environment.As noted above, a con is that the Noyafa may be too strong. Its output rating is an enormous 30mw. With this high optical output power, serious issues could occur if one looks at the beam directly. When testing cables with this VFD out in the field, I always use end caps on the fiber lines to reduce the chance of any direct encounter with the beam.The product really shines(pun intended!) if one is working in a brightly lit environment or possibly outside.
