NOYAFA NF‑8209S Network Cable Tester – Upgrade Ethernet Cable Tester with PoE Detection, NCV Voltage Test, Cable Length Measurement, Port Flashing & Anti-Interference Scan Modes

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.

When I bought this thing I thought it was gonna be nothing but a potential total waste of money. Surprisingly the POE functions work which is what I bought it for. The distance meter works you have to have an end on it but works. All the features work, especially the wire test, and basic toner. This does cheap looking thing works. The toner is like cheap junk plastic, but it works. Cheap alligator clips however it’s a simple solder repair Its not as strong as a fluke or Klein quality but for POE it’s perfect without needing to spend $400+ For just that feature.i used it to tone POE in a Marriott hotels, when access point cables are not marked i can tone it to the poe switch or router. Used it on Military bases for large Exchange stores worked. Definitely it paid for itself. Extremely surprised that this thing actually worked if it breaks I’ll just buy another one because it’s still a lot cheaper than spending another $400 on just one feature I need. I got a Fluke micro scanner, fluke inteliprove, greenlee network toner, Klein scout 2 & 3 and those are great quality tools. This little cheap meter handles a POE feature like a champ. Very great features for a fraction of the price. A great buyx. And like I said if it breaks I’ll buy another one it does the job well and pays for itself with several jobs as a Field IT contractor.

So far so good. It does exactly what I need it to do and does it relatively well. It does have a very cheap plastic feel, so I’m not sure of it’s durability. Probably will not survive too many drops to the floor.

I was scratching my head wondering why even though the cable passed the continuity test why my internet kept dropping. I tested the cable connecting my ONT to my Router and confirmed there were breaks in the middle of the etherent line depending on how the cable flexed. I replaced the ethernet cable with a more robust one that came with my 10gbe network card and my internet has not dropped once since. It really was the cable the whole time. The length tester is hands down the most indispensible feature of this tester. It's more than half the price of a similar fluke tester but does the job plenty good for a hobbiest home networking guy like me. Continuity test is no longer enough, I'll be checking every cable i get from now on with this tester! The UI is super easy to use on the tester, easy to navigate. The backlight is perfect and the display has pretty good viewing angles for those moments you're contorted in the attic trying to check cables. USB C for recharging is also really great. The digital toning feature was kinda hard to use and felt useless vs the analog one which was much easier to use to identify cable runs. The only thing, and i won't deduct a star for this, the earbuds in the photo were not in my kit :(

I am a network operator, not a electrician, so this tester doesn't get used on the day to day. My first RJ cable tester was: https://www.amazon.com/gp/product/B01M63EMBQ/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 Works great for testing a crimping here and there, but very primitive. I needed an upgrade. I've come onto job sites where someone else has run the RJ45 and nothing is labeled. I'm standing in front of a 24/48 port switch (nothing in the port description) and users are having connectivity issues: the 'wand' in this Kit is extremely useful. Once I've track down the local and distant ends, a quick 'pin-out' check (a diagram on screen that shows any 'shorts' or 'crosses' that's stopped me from tampering with someone's laptop >ipconfig /flushdns/renew/release) and I've eliminated one more point of failure. Haven't utilized the PowerOverEthernet or Length features. I've tested them, but not able to put the information (power output) to use as I wont be familiar with the end device and it's power requirements. That's troubleshooting configuration setting, not cable integrity. There are higher end testers that can conduct speed and ping tests on a port (you'll need the port config's and again: that's beyond cable integrity), or tell you what type of device is on the distant end. If you really need to dig that deep, you should have remote access to the switch, router, hub, bridge...etc, and see at the exact setting the cable was dedicated for, and not through some scanner. You should also have some understanding of the network design. Unless the contractor who laid the cabling had no consistency when dedicating jacket colors to end devices. For example: blue cable jackets will always go to workstations, white cable jackets will always go to Hot Spots, black - cameras, grey - VoIP phones... These higher end testers can come with a lot of fancy features, but rarely will they be of use. For troubleshooting layer 1 issues, this kit has everything you'll need. Even if a cable is 100%, being able to isolate what port it is plugged into on a switch lunges you into the next step of troubleshooting. Countless times: it was either a wrong port, or a port configuration. With the wand, I moved along in the elimination process SOO much faster.

This is a good, inexpensive cable tester. It allows toning for signal strength to try to locate pairs or cables and then allows for a continuity check. Its 2 faults for my use is 1) line toning definition is not nearly as good as my more expensive Fluke 200 set and 2) there is no charge indicator except dead device. The latter issue is somewhat mitigated by USB C charging.

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.

I bought this new, but received an open-box unit. Quality control is clearly lacking: Hardware Defect: The continuity test is completely unreliable. It consistently registers Pin 1 as closed/shorted even when the port is completely empty. Condition: The packaging was unsealed prior to delivery, suggesting either zero factory QC or that someone else's defective return was restocked and resold. A cable tester's only job is accurate fault detection—a false positive with nothing plugged in makes it useless. Skip this and get a more reliable tester.

Prima tester. Geeft direct resultaat van de connectie. Ook de lengte is een goede indicatie of de gemaakte verbinding gelukt is.

As I'm not the best installer, I had 3 cables that I'd run through my walls work poorly or not at all. I was using shielded cable (in my amateur radio station, where there's lots of electromagnetic energy present) and I was happy to see that it tested the ground connection as well as the 8 conductors. The continuity test is most useful, where you plug the supplied passive device into the far end and it tells you which wires failed, or were wired incorrectly, or if the ground is not conducting. The TDR function which measures cable length can sometimes help with identifying which end is in error. I had one connector where the wires weren't pushed in all the way and the TDR said this was an open circuit while the other end it was the expected cable length. Another cable that must have had marginal contacts showed the correct lengths at one end, and several different lengths at the other. Replacing the latter connector was the correct choice. I had one socket that had the middle (blue) pair reversed. The continuity test found that straight away, and after inspecting the plug at the opposite end and seeing it was correct, opened up the wall panel and corrected it. There is also a function to identify cables using a (powered) wand which emits an audio tone when near the cable that the main unit is plugged in to. This is another handy feature for narrowing down problems, although for shielded cable you need to have the wand near the connector rather than anywhere along the cable. All in all I fixed everything in a single afternoon, after having them in an unusable state for over a year. So it was money well spent. The unit comes with a little carrying case, and some short cables for testing RJ45, RJ11 and bare wires using alligator clips, and batteries for the two units that need them. The manual is clear enough, although does suffer from somewhat poor use of English. I'm very glad I bought this unit and it works as advertised.

Useful tester with included cables a bonus Used for both testing cable and searching for cables
