The structured cabling architecture (topology) is typically of a hierarchical stellar type, and can have floor distributors (Floor Distributor or FD), building distributors (Building Distributor or BD) and district distributors (Campus Distributor or CD). Each distributor is made up of standard cabinets, (19-inch rack), which can house both passive interchangers and active devices.
Each workstation (PdL or TO) is served by one or more cables, laid in special channels or pipes; these cables are connected on the one hand to telematic sockets installed in suitable wall or floor plates, on the other to patch panels positioned inside the racks.
