Cable sharing is a technique for constructing SCS , in which the signals of several applications are transmitted over one 4-pair cable (category 3 or 5). According to current standards, no more than one application can be transmitted simultaneously via cable, requiring the 5th (up to 100 MHz) category (for example, Fast Ethernet ), the remaining pairs can be used by applications with a requirement of no higher than 3 category (up to 16 MHz), in particular telephony and ethernet .
In some cases, the term cable separation is also referred to as hybrid cables, in which there are both fiber-optic channels and twisted pairs.
To connect the terminal equipment, either the cable is routed to several outlets (while losing the versatility of the SCS), or they use Y-adapters.
