“Divide and rule”

As a horizontal cable in modern SCS, a four-pair balanced cable is used mainly. It is known that for signal transmission in Ethernet and Fast Ethernet networks, only two out of four pairs are used. The remaining pairs are virtually idle. The technical characteristics of modern cables in terms of the NEXT parameter are very high (see Fig. 1), which allows the use of free pairs for transmitting analog and digital signals without any noticeable effect on the operation of the main application.
