Well, I'm not sure about 48 port. I have several of these:

which are 24 port 10Gbase-T switches. I got them in.. late 2008?
2009? Not sure offhand.

 From the same manufacturer there's the more recent

also 1U, which appears to be 48 port or more and to have a copper 
version but I've not actually seen one.

And both models are stackable.
