Ethernet Switch- what's the point?

If a surge is of concern to you adding a fmc ( fiber media converted) will eliminate

I use this on the incoming cable TV to Wifi router bridge which are about 4' apart but I don't have the funds to run 50' of fiber.  Also, the power adapters of the media converters themselves are additional sources of noise and surge paths.

However, doesn't change anything, search for John Swenson and leakage current (made up term) on audiophilstyles (can't post links to that site or your post are removed)

Freddy @fredrik222 :  trying to avoid any responsibility for the lies you post. Let's see if my LINK to Audiophile Style is removed....

@cleeds you mean like you did when you entered this thread? Question still remains, why do you fill up the forums with easily verifiable false statements?

@fredrik222. The difficulty here is that a lot of people's experience contradicts the basic "facts".

As has happened throughout the history of science, in these situations advances happen when the apparent contradiction between "facts" and experience is probed and understood.

And yes there is the danger of snake oil, confirmation bias, and placebo effects, but effort needs to be made to rule those out rather than simply dismissing the empirical evidence out of hand.

BTW - that is a general rather than ad hominem comment.
