NOYAFA NF-8508 Network Cable Tester with Optical Power Meter, CAT5 CAT6 Cable Toner Ethernet Cable Tester, RJ45 Network Tester, VFL PoE QC Test Wire Tracer Port Flashing 200M Length Test

I've been using the NOYAFA Network Cable Tester extensively and I'm thoroughly impressed with its capabilities and affordability. This versatile tool has made my network installations and troubleshooting tasks much easier. It features an optical power meter and VFL, making it invaluable for both fiber and Ethernet cable testing. The tester supports various standards including CAT5, CAT6, RJ11, and RJ45, which covers almost all my needs for telephone, Ethernet, and video testing.The build quality is solid, providing the durability needed for regular field use. The device is also quite intuitive, making it easy to use without constantly referring to a manual. The inclusion of a PoE tester and wire tracer further enhances its utility, making it a comprehensive solution for network testing. The value for money is exceptional, considering the wide range of features it offers.Overall, I couldn’t be more satisfied with the NOYAFA Network Cable Tester. It’s a must-have for anyone involved in network setup or maintenance, providing accurate readings and helping to quickly identify and solve cable connectivity issues.

I like it a lot. Great features, and it helped me troubleshoot a difficult to find problem. Only negative is you have to move the wire between two different ports on the unit depending on the test you're running. A little cumbersome, but not to the point where I'd take away any stars.

I feel like I got good value for what I paid. All the features seem to work fine, as does charging. I mostly use the unit to troubleshoot my homemade cable terminations in my house (POE cameras, hardwired connections to media players, desktop PCs used as media centers, interconnection of data switches, etc.) and it's solved several problems. I also use it to remind myself (hmmm...) which cables are which. I probably should do a better job labeling them. I've tested the fiber features on some old cables I have, but have never had any reason to use them for any real purpose. It doesn't seem particularly durable or built for hard use, but I just use it from time to time.One huge con of this set is that the instruction manual is pretty much worthless. Whoever wrote it made a sincere effort, I guess, but you're much better off just to jump in and start picking selections on the test unit and seeing what happens. It's hard to go too far wrong with this approach.

I needed to replace my old toner/tester. I came across this one that a co-worked used.I love the functionality that it provides. I can check ethernet cables, tone, as well as a few other options that I don’t really use.Both feel good in the hand, and made well.The screen is easy to read. You select the test, and it shows you which connector to use. Both have rechargeable batteries. Like others have said, not all charging cables work. I opted to use the supplied cable. No issues so far.For the price, it’s worth it.

Purchase this as an all-in-one tool for quick tests on the field, but most of the features do not work correctly. First, I have no Idea why it uses so many different ports to do the same thing that other devises do with one. You will think is for accuracy, but you will be wrong. Which brings me to my biggest problem with this device, its not accurate at all.The cable length is off by over a foot when you can get it to read. Most of the time it will only read 2 or 3 out of the four pairs marking the others as bad. These are factory made cables, clearly marked, and verified with a Fluke MS2-100. I can understand a small variance from one device to another, but over a feet difference is a big discrepancy.The Flash feature to identify ports on switch will not work on newer Cisco equipment, what we use in our environment. The light on the port will come on for a couple of seconds and it will go away, never coming back. It would work properly on older devices.The PoE features do not give accurate readings. Assessed on different Cisco devices and the voltage was way off.And my biggest gripe with the device, the main reason I purchased it, the OPM reading. It is off by 1 dbm or more. I compare the readings to two other devices, a TM290T and a cheap YGGYM optical power meter. Both the TM290T and the YGGYM were giving me a reading on a single mode, 5m cable, of -6.4 to -6.1. The NOYAFA was giving reading between -7.2 to -7.6 reading.
