What do UTP, SFTP, FTP, STP, and SSTP represent in network cable Cat7?
These prefixes refer to the various wire shielding configurations used within the cable body:
Cat7 (a) UTP cable: The unshielded twisted pair design provides sufficient EMI and signal attenuation protection to meet the baseline requirements of this standard.
Cat7 (a) F/UTP cable: Foil/unshielded twisted pair cable provides more signal loss protection than the UTP version.
STP Cat7 cables and FTP Cat7 cables: shielded twisted pair or foil twisted pair cables are closer to maximum safety.
SFTP Cat7 cables and SSTP Cat7 cables: shielded foil twisted pair or shielded twisted pair provide the most comprehensive additional signal protection.
