    IDF – intermediate distribution frame

    Short for intermediate distribution frame, a cable rack that interconnects and manages the telecommunications wiring between an MDF and workstation devices. Cables entering a building run through a centralized MDF, then each individual IDF and then on to specific workstations. For example, an enterprise that encompasses a building with several floors may have one MDF on the first floor and one IDF on each of the floors that is connected to the MDF.
