Increasing use of network and data cables between audio and video devices on location calls for a Category 7 cable that is designed specifically for deployable use. Basic Category 7 cable is a relatively inflexible installation cable, and even the slightly more flexible patchcord type still has very poor handling characteristics in deployed (as opposed to patching) applications. This Category 7 S/FTP construction cable has been designed specifically for the professional audio and video user who needs longer cable runs, and is intended to handle like a typical (but large) microphone cable. It has an extra-flexible individually screened 4 pair core structure with larger conductors for lower loss (0.25 sq.mm, 23AWG), an overall braid screen that maintains Category 7 performance, then a rugged polyurethane outer jacket, to give good flexibility and handling characteristics.
It is not suitable for use with most standard RJ45 connectors due to the 9.3mm overall diameter. A suitable connector is the Neutrik Ethercon NE8MX6 (see application note below).
The Category 7 standard provides performance up to 1000MHz, and is suitable for Gigabit Ethernet, 1000Base-T and other high speed applications, as well as analogue and digital audio. Category 7 defines more stringent specifications than those applicable to Category 6/6A, particularly in crosstalk between pairs.
