Testing Ethernet switch

@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. 

@tonywinga  here is an article from an industry source:

Yawn, freddy, yawn. 

@jeffrey125 yeah, actually gaining knowledge is tedious, the majority here never bothered with learning anything about anything. That is very apparent.
