NOYAFA NF-488 POE Cable Tester for Power Over Ethernet, Network Cable Continuity Checking, Switch Loop-Back POE Detector

I'm a telecom professional and this tool is great! I'm able to accomplish multiple tasks with this one kit that would normally requires multiple seperate testers! I was a little skeptical at is capability for the price but once you started getting the hang of its wonderful! Im able to test continuity, tone and trace cable, determine the length of cable and even test POE! There is a little manual that comes with it but it's not really a complicated tester. Just make sure you are using the right port on the tester to match the test you are trying to conduct! The cable toner i found to be very adequate! You do have an option to test via digital or analog settings and you can adjust the sensitivity for a solid confirmation. It does come with various adapters for different testing conditions. I was to thrilled about the case. I like the layout and the availability of storing things away but I'd prefer a hard case to house it. There have been a couple times ive had something on the toner wand driving and it would turn on and beep but if thats just a preference thing BOTTOM LINE: Highly recommend for the price! The convenience and funtionality that is packed in this kit is definetly worth this price!

I've had good luck with this so far and I'm pleased with the very fair price. I consider the USB-C charging (for *both* Tx and Rx units) well worth the small upgrade cost from the next model down in their line. Mine did arrive with the receiver (Rx) unit turned on and its battery stone-cold dead. But once charged, everything works as advertised. The controls are simple and intuitive and the display backlight very helpful. In my experience, tools like this typically get used in poorly lit, overcrowded closets. I can't attest to the precision of the distance test, but I know it's reasonably close at my backbone length of around 75 ft (~23m). Even a +/- 5% is very useful for troubleshooting in my setting. One word of advice: They provide a USB-C cable but you're supplying your own charger. I was unable to charge using a 'smart' charger (e.g., Anker IQ). Apparently it only wants an older-style 5V supply. In general, this is something to be aware of with a many devices on the market. I made the mistake of recharging a dive computer with the included cable connected to my own 9V-capable Samsung charger and melted the plastic housing. Not every mfr. implements the necessary circuitry for the smart chargers to correctly detect and adjust. At least in this case, connecting an inappropriate charger PREVENTED charging which might have caused some damage. As such, this is not a con. Another thing to be aware of is that it's very easy to switch between tests and forget to move your cable. There are different RJ45 jacks for different functions. I'm embarrassed to admit how many times I did this. Slow learner, apparently.

Works great under ideal circumstances. Length function seems quite accurate and, if it shows different lengths, helps determine bad wires/connectors. Continuity test, flash test, reading POE signal, and sending a signal over a wire so I can detect it with the wand all work. Length shows pairs of wires, continuity shows each individual wire. I had space so I added a punchdown tool to my kit. Also, the buttons can press easily through the case so I added some hot glue around the power buttons. The tester works for about 5-10 minutes in sub zero temperatures. Haven't dropped it yet but it doesn't appear to have any protection against that. Tester uses 3x AAA batteries. Wand uses 9v. Would be cool if they used the same type or even cooler if they had usb charging. Still a good product, but room for improvement.

So I can't say enough about this little, capable, affordable piece of kit. I do my own cabling for my network. I largely live in Cat 5e. I had an old led type tester that would only show me whether I had a fundamental connectivity problem. That was great for awhile. But recently I moved over to doing pass-through connectors. I noticed on my network switch that my connection speed for a new cable was only 100Mbps though it should have been 1000Mbps. My old tester showed everything was fine, but it obviously wasn't. So I splurged the $50 for this little tester. I confirmed that my crimps were bad due to a faulty crimper. I now speed test all of my new cables with this tester by connecting the tester to one end of the cable and the other end to a spare gigabit switch I have. I liked that it did continuity, length testing and toning. A nice feature is that you can get a reading of the wire speed when you use the toning/flash option. The flash option was great as I wanted to map out my network. I connected to each ethernet jack, connected the tester via a short cable and went into flash mode. I then went to my switch where I could see the light pulsing slowly (differently than regular flashing.) I then noted which switch port that particular jack was connected to. I found that it tones wires fine too. I do run POE+ devices too. So I'll check that out eventually. Anyway. I like it. It wasn't that expensive and did more than I needed it to do. Hoped this helps.

Excellent value for money. My NF-8209 uses standard batteries (included) one 9V for the probe and three AAA for the master (unlike the rechargeable version) which I am glad for! Because it can do so many different types of tests, it takes a few seconds to switch the cable to one of the 4 possible test ports and then select the correct on-screen test. The best feature is the ability to tone-test and flash live powered POE ports. Selecting POE SCAN, with the probe set to DIGITAL works well even if the port is not POE !!! Damn good tool, just purchased it but I can already know I cant live without it! Carlyle

I've used this lots for tracing network cables around the house, testing newly terminated network connections and for checking lengths, and it works brilliantly, it's been so useful. Other than remembering to move to the right network connection on the tester when you change modes, it couldn't be easier. The included cables are for Cat 3 voice connections, so if you're testing a Cat 5/6 connection don't use those, use another cable if you're testing say a socket, otherwise it will only test 3 out of the 4 pairs.

This kit was perfect for wiring a home surveillance and network with a reel of CAT6 cables and terminals. I mis-wired one AP cable THREE times in a row! If it weren’t for the device it would have been a headache. The scan wand is very useful, too. Helped me identify and label a number of cables that lost their labels during their transit in the conduits.

Funciona perfectamente aun que aun no lo uso en distancias mayores a 10 metros.
