Definition
A main distribution frame (MDF) is a central hub in telecommunication networks where external telecommunication lines connect to internal network devices through intermediate distribution frames (IDFs).
Communication cable lines enter the building and connect to the MDF before connecting to individual IDFs in different locations across the building or campus.
This setup is commonly used in multi-tenant facilities and large buildings such as hospitals, office buildings, and universities to manage the distribution of data and telephone signals.
The MDF is an essential component in telecommunication systems. It facilitates the distribution of signals to appropriate locations within the building, ensuring the system is organized and efficient.
MDFs and IDFs Work Working Mechanisms
The MDF has cross-connects and patch panels for easy cable connection and reconfiguration. In multi-floor buildings, the MDF is typically located on the ground floor and connected to the public telecommunication lines entering the premises. Then, it connects these lines to the IDFs on each floor, and the IDFs connect to individual users.
