NOYAFA NF-8601S TDR LCD Network Cable Tester Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable,PING/POE

Product works as advertised and came on time

For the price this is a great tester. I have been using this one for over a year and it does a great job mapping cables and the toner has a strong signal (note that other analog probes will not work with this, you have to use the included probe.). The tone is so strong that it worked loud and clear when my other analog toner would not reach the telco room from 4 floors away. Seems to be able to tone when plugged into a switch. One thing I always do with an unknown cable drop is check for POE first. I had a previous toner fry its port when I plugged it into a bad POE line. Just wish it had multiple ID remotes, just having 2 remotes will save on the back and forth walking when trying to ID a cable. If you lose the remote then try to contact the seller for a replacement. The length tester is only accurate if you calibrate to the particular cable you use because of how tightly the pairs are twisted. Length test does not work well on short cables (less than 20 feet I think). Having DHCP and ping tests option is a huge time saver since I don't have to pull out a laptop each time to check for internet connection. Most other brands charge way more just to have these features. Most can't even tell you an IP. This tester does it all for way less, has a bright color display, and rechargeable battery.

This review is about long-term reliability. When the unit was new and worked it worked great and was a good value. I had no problem with it. After ~2.5 yrs I found the unit unresponsive and could not get it to show any sign of life again, even after replacing the battery. My use was only ever occasional, and it had sat (in case) in the back of the car unused for quite awhile before I found it dead. It was unsurprising initially, as I expected that the battery would have run down. Attempting to charge it had no result, with no light or any sign of life. Then replacing the battery made no difference, and attempting to contact the company through website was unsuccessful as well so I have had to give up on it. As long as it works it will probably do well for you, but be warned that it may not last.

Excelente compra. Muy util.

The tester has a graphical screen which is very easy to navigate. This tester has more features the the "yellow" units costing 8x as much. It also takes into consideration the type of cable being tested (Cat5e, Cat6, and cat6A) due to the different characteristics of the cables. I tested the cable length on a known Cat5e cable length of 90 feet using the built-in factory calibration against a "yellow" brand microscanner. This unit measured more accurately at 92.2' of length. The "yellow" unit measured a low of 94' and a high of 96' feet. It displays cable pair wiring correctly and easy to read. Port flash, mapping, pinging a device, POE, toner all worked great. POE voltage measurements measured the same as my Fluke 87. My only concern would be the built-in lithium battery. I would personally prefer regular replaceable alkaline batteries. Overall, I would recommend this unit to anyone looking for a network cable tester without spending a ton of money.
