Fiber optic cable entry point for communication equipment room
Backbone cabling provides high-capacity interconnections between entrance facilities, equipment rooms, and telecommunications rooms. It typically consists of fiber optic or high-performance copper cabling, supporting gigabit and terabit speeds for large-scale enterprise networks. Fiber optics is also a horizontal option in TIA 568, but not often used because of the higher cost of electronics. The exception is where high bitrate networks or future upgrades are expected. 1 defines the entrance facility (building entrance) as the point in the building where cabling connects to the outside world. Buildings and their communications requirements have never been so diverse which in turn requires an almost infinite degree of flexibility and. A critical piece of an advanced design is the building entrance termination point, where the OSP and IFC cables are joined, managed, distributed, and protected.
