Customers Love Us


We're doing some major remodeling, and we've decided to do much of the work ourselves. We wanted this NOYAFA Network Cable Tester for our network cables and troubleshooting. The optical power meter and VFL adds further versatility.

I did have to get a friend who is a fiber optics installer help me figure it out. Once I got it figured out, I was on a roll. It helped me accurately measure cable lengths. Whether I was running Ethernet cables through walls or ceilings, knowing the exact length required for each cable was crucial to avoid unnecessary clutter and ensure a clean installation.

The device has a Variable Frequency Laser (1Hz, 2Hz, and Static) that is good for shooting light to find faults in fiber or locate where a connection is on a patch panel.

Also has an Optical Meter to test how strong the light coming in is from another Switch/Router/Media Converter. I keep this in my car and it's saved my but a few times when I ran into fiber issues and was able to do some quick troubleshooting. Just gotta remind myself that -16.00 db is the "normal" threshold for a good fiber connection.

I got this to upgrade my tools for work, it’s been great for the most part. Wish it came with more attachments for the OPM for some of the other fiber plugs that are made.

The battery life is great, I use it almost daily and I seem to get weeks out of a full charge under those conditions. I’m so glad it’s regargable because my last toner flew through 9v batteries.
