Shielded UTP CAT5e cable is generally referred to as STP UTP CAT5e or Shielded Twisted Pair UTP CAT5e. This term, however, is used to refer to many different styles of shielding. The most common type of shielding uses what is called a screen.
This screen is a metal covering that goes around the entire set of 8 wires found in UTP CAT5e cable. This can be done by a single solid foil wrap around the wires, braided strands of cable wrapped around all the wires, or a combination of the two. This type of cabling is very effective at blocking any EMI that could cause problems in most installations.
If you want to ensure the proper operation of your network, we would recommend using STP cable like this for all in wall and other critical runs of cable. This way you can rest easy knowing you’re getting the most speed that you can out of your network.
