If the facility is big enough the utility of twisted pair becomes quite 
limited, both due to distance and differing electrical potential, 
multibuilding campuses in particular make this is a nonstarter.

In one facility I'm in, I'm over 300 meters from each of the MMRs, with 
the results that the OOB for the serial console server for out equipment 
located out there in the MMR's being on serial over fiber transceivers 
connected by om4 multimode.
