What is the difference between the types UTP, FTP AND SFTP?
UTP, FTP AND SFTP are terms used when discussing the typical specification style of Ethernet cables. All these references offer is whether the Ethernet cable in discussion is shielded or not, and if shielding exists, what type of shielding is applied in the basic structure of the cable. UTP; Unshielded. FTP; Aluminum-Mylar Foil Shield. SFTP; inner Aluminum-Mylar Foil Shield, covered by an outer tinned copper braid shield. ProPlex PCCAT5P and PCCAT5EP have maximum shielding; 100% Aluminum-Mylar foil shield with an outer 80% tinned copper braid shield-SFTP.
