MDF-IDF CLOSET DESIGN
Integral to the telecommunications infrastructure in buildings are the secure communications rooms, consisting of the MDF and generally one or more IDF's. These rooms must be secure, environmentally conditioned and clean before Telecommunications can work in them, especially as fiber must be terminated in these rooms, requiring a very clean environment. Expensive and delicate networking devices, requiring environmental conditioning, also are housed in these rooms. In this regard, the MDF and IDF's shall be completed, including environmental conditioning, and completed early in the project timetable. In particular, all penetrations shall be completed and sealed before telecommunications work can proceed in these environments.
The MDF also serves as the distribution point for voice, video and data, and shall be secure to protect the integrity of these systems. Grounding and bonding shall be provided in the MDF in strict accordance with industry standard, and extended to all IDF's.
