“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.

Custom solutions for local networks of small offices

From the school bench, we are all familiar with some of the laws of nature, which are therefore called the laws that cannot be violated. However, in addition to laws, there are rules, of which, as you know, there are exceptions. To make life easier in the manufacture of technical products, people also came up with standards – rules that apply only to manufacturers. Continue reading
