What does IDF stand for in distribution frame terminology?

• A. Internal Distribution Framework
• B. Integrated Data Framework
• C. Internet Distribution Facility
• D. Intermediate Distribution Frame

Answer: (D)

In distribution frame terminology, IDF stands for Intermediate Distribution Frame. A distribution frame is where cables terminate and cross-connect so lines from the main network can be handed off to end-user circuits. The main distribution frame (MDF) sits near the building entrance, and trunk runs typically feed an intermediate distribution frame on each floor or section. The IDF then connects those feeds to the local patch panels, so you can reach individual desks or rooms. The word “intermediate” captures its role as the between-point between the MDF and the subscriber equipment. Other phrases you might see aren’t standard terms in this context, so the widely used name Intermediate Distribution Frame is the correct one.
