Good question. I don't have personal experience with the modules but I
note that descriptions on the web page excerpted below are nearly
identical, with single difference being 'FTP cable' for the X7348
module.

nst/01overvw.htm#1122881
The module has 48 RJ-45 connectors for use with either Category 3,
Category 5, Category 5e, or Category 6 UTP cable.

FTP (foil screened twisted pair) cable is a cable containing multiple
pairs of copper wire enclosed in a sheath of aluminum foil. It's used in
wiring systems in buildings or other environments where heavy noise
adjacent to the wire might cause interference. The foil provides
insulation not afforded by UTP (unshielded twisted pair), the most
common kind of structural wiring. The disadvantage of FTP is that it
requires somewhat more care in "earthing" (grounding) than UTP and
electrical impedances must be matched when connecting to UTP. Typically,
FTP might be used in a factory setting and UTP in an office setting.
