Testing Ethernet switch

Match made at ASR Freddy and the Geek. 

More snide remarks. No identification or properties. 

@tonywinga you have no relevant experience or knowledge, yet you have the arrogance to argue facts about a topic you have demonstrated over and over again is far far beyond your comprehension, and then call me a clown. It is absolutely hilarious.

i have a civil engineering degree in computer communications, I have numerous certifications from Cisco, Juniper and many others, at the Expert level, and I have worked with computer networks all over the world for almost 25 years. 

@mgrif104  Hans just regurgitates the debunked white paper by John Swenson. 
unless you buy counterfeit crap from second hand Chinese markers, noise is not a factor in Ethernet, especially not in residential applications. 

For starters, Ethernet is balanced, so common mode noise rejection is by default, which remove the noise below 1000MHz. That is just one of the noise rejection methods and does not include error correction.

another point, modern Ethernet is a point to point connection, it is terminated between each connection and the signal is read and recreated for every hop along the chain. So no noise can travel beyond any connection point.

@cleeds  per usual, selective quoting and citing of reference materials to highlight something that isn’t there. But at least you admit I am correct.
