building distributor (wiring) (BD)
The building distributor (BDC) forms the transfer point from the off-road cabling to the building cabling.
The building distributor contains all the support points for the building cabling in the form of patch panels and patch fields as well as the support points for the ground cabling. If necessary, these can contain a media-technical conversion of optical fibers to TP cables or other cables. From the building distribution panel, connections can run directly into the offices to a junction box in the parapet trunking or floor tank.
In fiber optic cabling, the wired building distribution frame is replaced by a fiber optic building distribution frame through which the floors and rooms are connected to the fiber.
