hi
I want to ask if anybody has tried Noyafa NF-8601S ? Is it good , durable and accurate ? or any advice, I want to buy good and affordable one . I googled for network testers and found Klein tools and Fluke are the best but both of them are expensive , and I found I can buy the most features that I need with nf-8601s with affordable price.
any advice would be appreciated
 
The stuff you buy directly from china tends to be suspect many times.

Part of the reason you pay extra for fluke is because there is a license fee fluke paid to the standards boards so they can say that their meters can certiefy cables to meet those standards.

It depends on what you are looking for. You can get a meter that checks the pairs are correct for a tiny fraction of that price even on amazon. I am not sure what the other feature are. A fluke meter can actually measure the crosstalk on the pairs......but there are many fluke meters and I have only used the very expensive ones.

The POE feature seems almost useless on that meter. It does not test the standard 802.3af/at form of poe. At least I did not find that string in their ad. It seems only detect passive forms of poe and all those are proprietary anyway.

So what feature is most important to you. That meter does not appear to actually measure the most important things that can tell you if the cable is cat5e or cat6a for example.

Generally you only need a fancy meter when you are professionally installing cables. Then you need a meter that can generate reports to show the customer that all the ports are certified. If this is for home use there are many in the $20 range that will do most the feature that one will.
 
Thanks bill001g for your reply , as for POE and as you said " it dosn't test standard 802.3af,at and bt" I think the POE test will show you how much volt delivered by each wire, that means you will know whether you have POE , POE+ or POE ++ (802.3af, 802.3at or 802.3bt) .
also the tester checks the continuity , and if there a cross between wires. I'm not sure , I watched some videos and read some information about it
 
Is the desire for this tool in relation to some troubleshooting or just for making sure your connections are good before powering up on a self-made run?

I would mention something really quick. In the US you cannot terminate low voltage cabling without a license. Of course, what you do in our own home tends to be your business, but the reason I mention this is if it is a job such as your new home being built by a contractor you cannot go in there and do so without a permit and licensure. You can be fined a very significant amount of money as well as messing up the process for your other required job site permits and tasks.

With that said, outside of the above snag(s), buy the good tool and I personally recommend Genesis cable if you can find a place to purchase it.

Nope 802.3af/at/ is not that simple. These are active protocols. The end device tells the switch it wants power by placing a certain resistance across a pair. The switch then delivers some power and the end device then request the amount of power it it really needs.

There really is no voltage to detect until the device requests. It runs at 48 volts so it will fry equipment if it just always provides power. A meters would have to have all the electronics in it to simulate the poe power request and then properly test for what options the switch supports.

Having pairs swapped a cheap testing can do. What a commercial tester can do is actually measure the crosstalk between the wires in the pairs and between the pairs. This is done to see if the cable was properly manufactures. It must send very special testing signals on the pairs to get this.

I am almost positive the meter you link and not detect 802.3 poe and does not actually test the cable for crosstalk.
