The Primary Distribution Structure The Main Distribution Frame (MDF) room acts as the building's demarcation point. It is the point at which the phone, data, and video building feed cables connect to the intra-building backbone cable that goes to each Intermediate Distribution Frame (IDF) room. From there, these same cables are distributed throughout the office space via panelboards located in various areas of each floor.
The MDF room also contains fiber optic splitters used to divide up the incoming fiber-optic cable into individual branches capable of being routed to different locations within the building or across town. Each branch ends with a fiber optic connector designed for easy connection to another splitter or fiber-optic cable. Splitters can be wall mounted or housed in portable metal cases.
Portable phones, computers, and other mobile communication devices need power to operate their built-in components such as microphones, speakers, screens, wireless network cards, and storage drives. These devices communicate with each other over telephone lines and the Internet using radio waves instead of electrical wires. The wiring inside buildings is not considered public infrastructure and does not receive government funding; therefore, it must be paid for by the business owner or leased from a telecommunications company. Leased access requires a lease agreement between the business and the telecommunications company. The cost of this private wiring depends on several factors such as type of device, length of service needed, location of installation.
MDF stands for main distribution frame, and it is a cable rack that connects and controls the IT and/or telecommunications wire between itself and any number of IDFs. IDF is for intermediate distribution frame, and it is a cable rack that connects and maintains the IT and/or telecommunications wire between an MDF and workstation devices.
A distribution frame is a central point at which cables from different parts of a building are joined together before being sent out to connect with individual computers or telephone sockets. In large buildings, several distribution frames may be used to distribute different types of cable to various parts of the building.
In small homes, one distribution frame usually does the job. It might connect to a telephone socket block, another distribution frame, or directly into wall plates. The type of connection used depends on how the network is designed. For example, a split-level home might have a separate distribution frame for each floor, with their own telephone socket blocks. When connecting distribution frames to telephone socket blocks, most manufacturers will offer two options: a male connector on one side and a female connector on the other, or vice versa. These connectors fit into matching holes in the equipment so that you can interconnect distribution frames easily without having to do any wiring.
Intermediate distribution frames (IDFs) are smaller versions of MDFs. They contain enough room for up to 32 terminal blocks like those found in office furniture such as telephones, computer terminals, and fax machines.
MDF necessitates high-throughput equipment. A computer/equipment room is another name for an MDF. The Intermediate Distribution Frame (IDF) connects the MDF to successive network concentrators. An IDF contains slots for individual network interfaces or modules. Each module can be installed in only one slot of the frame; thus, each interface has its own unique ID number within the frame. The IDF provides a central location for connecting input/output devices to networks.
