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

This is a good product. They should write a better use manual for it showing which of the three RJ45 sockets to use for each test. Happy with my purchase.

I looked at all of the inexpensive testers on the market, and chose this one for home use. I have a fairly extensive network at home, and all of the features on this were things I can use there. Honestly, I have access to just about every tester on the market, so if I need anything better, I just borrow it.This tester has some of the important features you need for home or a small network business. Specifically:- Basic PoE Testing - useful to make sure your switch is providing the correct power.- Cable length: This is a capacitive test not a TDR. What does this mean?First of all its not going to be as accurate as a TDR tester. Its accuracy is "≤20M+/-1.6M,20M~100M+/-2.4M,≥100M+/-3.2M" which means it can be off by about 8 feet on a cable under 100M.Next capacitance varries based on the wire you use so it is possible that it could be better or worse than that.- Continuity tester: Wiremap, fault test, etc.- Cable locator toner and wand- Port flash mode with speed identifier: (hated this! It kept turning off the flash mode before I could find the port!)- PoE Test: End connect, and mid-span testing for PoE with 802.3af/at detection and non-standard and shows voltage on each connection used.- Cable scan: Detects shorts, crossed pair, split-pair, open, loop-back, and has a detector for shield.- Visual fault locator for fiber (Just for a laugh... they say in the manual NVL: 10Mw... I think they meant 10mW! If you have a 10Mw fault locator, you just blew a hole through the fiber, the equipment, the floor, the wall, the neighbors building honestly I'm not sure how far a 10Mw laser would go!-Relative optical Power Meter for light levels including the following wavelengths: 850/1300/1310/1490/1550/1625 ( Wavelength in nM)-USB - C charging-A LIGHT! on the receiver!!!! As in FLASHLIGHT!!!Now the Cons:-Multiple ports for RJ connections that depend on the test you are running. You have to pay close attention to make sure you're on the right port!!!- The enter and back buttons are reversed (at least as far as i am concerned) The enter is on the left and the back is on the right. Its so annoying, that I'm almost tempted to rip it apart and rewire the pads.- If you are trying to blink a port and you are switching from port to port on your patch panel, the blink mode will shut off by itself after a short period. If this is from a remote jack, you have to have someone there to restart it.Overall I'm happy with this test unit. It does what it says, and i haven't had any real problems with using 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.

Awesome tool - Has saved me hours in cabling trouble shooting

Took delivery of a factory sealed unit. Attempted to test multiple known good cables and one suspected bad cable using the continuity test. I was expecting straight lines (on a straight-through cable) showing a connection between pin 1 to pin 1, pin to pin 2, etc. But instead, every time I ran the test I got a different and non-nonsensical result showing random pin 1 to pin 7 or pin1 connected to multiple pins when I know for a fact that the cable was a straight through and working when I pulled it out of the network. Oddly, this tester has several different ports based on the type of test being run and I did make sure I had the cable connected to the correct port. The length test appeared to work but I bought this specifically to confirm pinouts and electrical integrity of the cable, and that clearly did not work so I returned the unit.

Makes short work of testing your rj45 cable runs, and then sorting them all after you forget to label them. The battery life has been great. Have tested and sorted a 20+ cables and it's still showing near full charge.
