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

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.

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 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.

This thing has a ton of features. It worked out of the box, and was jam packed with features.I was using it to determine where a break in the cable was, and it told me the distance. It is wonderful.Highly recommended!

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.
