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 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.

This is a great tool for every IT guy that has to deal with installing or troubleshooting cabling. It does the same as the more expensive 'yellow' brand. The only difference is that the yellow devices use only one connector for all functions and this one has four different ones for different functions, which can be a bit confusing sometimes, hence the 4 stars. It does indicate on the screen which connector to use, so that helps. The interface is a bit clunky, but once you get the hang of the buttons, it's not bad, so for the price, you can't beat it.

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.The Ethernet parts work well too.Positives:Flashing Port = checking for connectivity. Provides speed, duplex, etc. It's good to know if I am even getting a good connection to start with.QC = If I am actually getting a copper contact on the termination. Good for when I make my own cables.Cont = This requires you plugging it into the port on the Toner on the far end so you can see what the cable is doing. Good for finding breaks and splits.Length feature is pretty accurate. Sometimes it'll show a pair that's not broken or anything as being way off. So you kinda gotta use your own judgement in some of these cases, but that's what we network engineers are paid for, right?Cons:Often find myself needing to use the port on the Toner for the most accurate results for the CONT and I have had some issues with using the actual toner correctly. But this likely was user error since I rarely ever tone anything out.All in all, it's definitely worth when working on a large network where you have a mix of copper and fiber. Especially when the name-brand competition has their products in the THOUSANDS of dollars price-range. So this definitely does the trick for me.10/10 recommend.

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.
