What are the maximum transmission lengths of an Ethernet cable?

According to general standards, the maximum transmission length in such a cable is 100 metres. This length consists of 90 metres of stationary cable and two times 5 metres for movement. This description is derived from practice, in other words from the area of building services technology. In buildings, the wiring is fixed in place and there is a patch panel with flexible cable at the beginning and end of the cable.
