Patch panels are primary used for stuctured cabling purposes (look "structured cabling" in google). What this means is that you have the medium for all
sorts of different applications. Here's and example of where structured cabling can come in use :
In the bedroom there is a RJ-45 jack. Sort of like
this. Behind the plate you have Cat5 cable going
to your network closet, where it gets terminated at a patchpanel like
this.. Right now, I want
to use those connections for Internet access so I plug the corresponding ports on the patch panel into a
switch.
Now let's say I bought a switch for my bedroom so I only really need one connection to my room for Internet access; What should I do with the other
connection? I could buy a couple
baluns and have television going through that
wire that used to have Ethernet going over it!
Those pics are taken from my home network. You can see more at
here. Warning, it's not a pretty site
🙂
Here's a pic of some patchpanels at my work. They are only used for Ethernet, but they make
it easier to manage the network. (

Hope that clears it up a bit. Hopefully ScottMac will see this thread, because he is the guru around here about structured cabling.
