Extralink cat. 5E FTP The Extralink cat. 5E FTP data cable is wound on a spool, which allows it to be unwound conveniently without the risk of tangling. The conductor is made of soft copper wire, and the cable core consists of four pairs of two twisted conductors. The core is wrapped with water-blocking tape, which provides effective protection against moisture. The cable is intended for outdoor installation, e.g. in telephone channels, mines and collectors, as well as on the walls of buildings with increased electromagnetic influence. Installation can be carried out at temperatures from -15°C to 60°C; after installation, the cable's temperature resistance range increases and ranges from -50°C to 60°C. The cable operates at frequencies up to 250 MHz.
