Belden 1885 ENH Cat 7 Cable

Belden 1885 ENH Cat 7 Cable

The Belden 1885 ENH Category 7 SFTP FRNC data networking cable is used for horizontal and building backbone cable. It supports all existing and proposed Cat 7 applications such as 100 Base TX, 100 Base VG AnyLan, 155 ATM and 1000 Base-T (Gigabit Ethernet), FDDI. The Cat 7 cable also features excellent stability of Impedance and NEXT performance.
