NOYAFA NF-859GT Network Cable Tester with Optical Power Meter 10mw VFL,for RJ45 RJ11 CAT5 CAT6 POE/Phone Lines CAT3, LAN Tone Probe Kit NCV&Ethernet Wire Tracer Fiber Tester Network Tools

I rate it a 3 for a few reasons. 1 - the innovation and price for a value network tester, 2- a few functions work but not that accurate, the accessories included at least they tried. Honestly, I thought this would be an awesome tool for my networking needs but it short fall my expectations. Sadly so I had to return it. The tone generator part works but doesn’t work when the end of the cable is on a switch like Cisco or unifi. The cable length tester isn’t that accurate as it is close but missed a few feet or more. The manual covers a few models and it is not in details on how to use the function dedicated to my tester just highlights of the usage, there is no ip ping, the cable quality check works good, cannot detect hub or switch location via cable just to the end of the connected switch or router, even to that is a guessing game at times, love the display and the rechargeable battery but for professional use no. Would be nice to have it touch screen and an on board guide. Some more improvements needed to be done to the device and wish if they have a pc interface and firmware update as well. Would love to keep it if these functions work well. I only used it twice and had to let it go. We have a six month project to network a whole complex and this tool would be awesome if it works accurately. The fibre optic part is a hit and miss especially on long runs, wish they would improve on that and speed check plus to detect internet and coupler or where the cable is broken like how many feet away etc. that is my take on it. Hope the next gen model improves on this and I may consider it in the future.

Toner does not work, and seller wont return my messages about a refund. This is the 2nd device I bought from Noyafa. The first one was a cheaper network tester. Found out it wouldn’t work half the time so I threw it away. Bought this one to see if its better as its a new product of theirs - nope, still garbage. Spend the money and buy a proper device from a reputable company even if it costs 3-4x times more.

Todo Ok

Toner works great, light meter needs to be set so it doesn't change settings.

At first, things were a little confusing as the menu system on the cable tester does not perfectly align with the instructions in the manual. Note that for the NF-859GT (what I am reviewing) is the last tester in the manual on page 28. Things I tested with their corresponding results: 1. "user alignment" test AKAs "cont" on the menu. This will test that your cable is built properly. You can test it locally (on either device) or test it between devices for runs in your home/business. This function seem to work fine. 2. "Scan" test AKA "wire detection" is the test used to find the other end of a cable. You plug the network cable into the "SCAN" port on the main device and then you use the probe device to find the other end of the cable. It has 2 modes (digital and analog). Both worked as expected. 3. "Flash" test aka "port blinking" in the manual. This test will cause the port in your switch to blink. It worked just fine on my switch (see picture) 4. "Length" aka "network line length test" in the manual. This is supposed to test the cable length. I tried it on a 15 foot CAT6 cable I have and it measured 17.5'. So not accurate at least in my testing. 5. POE test - this checks the voltage coming out of a POE switch. It worked fine (see attached picture) 6. "QC Test" aka crimping test in the manual - This tests your crimps. It works fine. 7. OPM - I do not have optical so unable to test 8. VFL - I do not have optical so unable to test There are a few quirks as you can see but overall, I think it does what it says and worth consideration if you are in the market for this type of tester.
