Cat. 7 cables are dual shielded (S / FTP) network cables, which have four wire pairs with bandwidth up to 600 MHz, which can support 10G BASE-T applications at a distance of 100 meters, especially suitable for servers, switches, distribution racks and other devices in data centers and high bandwidth integrated cabling systems in smart buildings. Compared to the Cat. 6A cable, 7 classes can support 10G Base-T applications at a distance of 100 m, Especially suitable for data center servers, switches, and equipped with Cat. 7 cables are dual-shielded (S / FTP) network cables, It has 4 wire pairs, Up to up to 600 MHz, A masked NEXT, ANEXT function, Also support Ethernet power supply (Power over Ethernet) applications (POE / shield line has higher bandwidth, And benefits from the shielding design of the S / FTP, Provide NEXT, ANEXT performance much higher than normal Cat.6A unshielded cables, It also supports Ethernet power supply applications (POE / POE +).
