Copper Ethernet LAN Cable, Category 5e, 4 Pair, SFTP Low-Smoke, Zero-Halogen (LSZH) cable
SF/UTP Both an overall braid screen (S) and foil shield (F) with unscreened twisted pairs (UTP). This cable is also occasionally referred to as an STP cable. Cables with an overall braided screen are very effective at protecting EMI from entering or exiting the cable.
