What Is an IDF?
An IDF, or intermediate distribution frame, is a secondary distribution point in a commercial structured cabling system. It commonly serves a floor, zone, or area by receiving backbone connections and supporting horizontal cabling to nearby work areas.
What an IDF Typically Does
Zone Distribution
Supports a specific floor or part of a building rather than the full facility.
Horizontal Handoff
Provides the local handoff point for work area and endpoint cabling.
Patch and Administration
Includes patch panels, rack patching, labeling, and structured organization.
