An Intermediate Distribution Frame (IDF) is an area, room, rack for wiring or cable from a Main Distribution Frame (MDF) - also called the Combined Distribution Frame (CDF) - and leading to individual cables installed for work area outlets (WAO) to support each piece of equipment such as workstations, personal computers and other end-user devices.
