Backbone systems are often called riser systems because most of the system, especially the cable, is installed in a vertical riser in many installations. The backbone connects the basement equipment or computer room with telecommunications closets on each floor in multi-story buildings.
FREMONT, CA: The term "backbone cabling" refers to the wiring that connects entrance facilities, equipment rooms, and telecommunications closets. Because an entrance facility is a point where a business's cabling system begins, and the telecommunications company's cabling system terminates, it is indeed the "backbone" of the entire system!

Purpose of Backbone Cabling
Backbone cabling flicks between different points of the cabling system itself, sending data from one location to another. At these points, backbone cabling can be transmission media, cross-connections and terminations. "Transmission media," in terms of structured cabling, means cables running between equipment rooms. Terminations are where the wires connect to a panel or piece of equipment, and another cross-connect cable connects two stops. To summarize, exits are the backbone cabling the highway for data and the connection points.
There are three main types of cables for backbone cabling: fiber optic, twisted pair (shielded or unshielded) and coaxial. Overall, fiber optic cable is the best option for any network, as it can support high bandwidth usage while still offering high performance.
Distribution of Backbone Cabling
Backbone cabling can be installed throughout a building's floors, connecting equipment rooms. Additionally, it can also connect floors.
In a structured cabling system, one significant distinction between the backbone and horizontal cabling is that horizontal cabling connects outlets and telecommunications. Thus, while structured cabling is installed throughout the building, horizontal cabling must connect work areas and workstations. When a data wiring company installs a structured cabling system, it must adhere to specific backbone cabling standards and regulations. These standards are critical because they ensure the daily operation of a structured cabling system. In addition, these standards may specify the physical location of cables connecting the telecommunications room and their labelling.
While backbone cabling is not the only type of cabling in a structured cabling system, it is critical. Backbone cabling transmits data between the structured cabling system's other subsystems, serving as the primary relay between the various equipment rooms, entrance facilities, and telecommunications rooms. If data is the baton, backbone cabling is the relay that carries it to the finish line. While it is dependent on one’s requirements and the type of pre-existing infrastructure in any building, fiber optic cables are typically preferred for backbone cabling due to their high performance and bandwidth capabilities. A data wiring professional provide a business with additional information about them and the entire installation process — from equipment basics for the whole installation process.
