Centralized Cabling
Centralized Cabling, ANSI/TIA/EIA-568-B.1
Introduced in 1997 as TIA TSB-72 (Telecommunications Systems Bulletin), centralized cabling was the first fiber premises cabling system architecture designed specifically to take advantage of the capabilities and performance benefits of fiber. Centralized cabling designs use the high bandwidth, low attenuation, and extended distance capability of multimode fiber to centralize LAN electronics in one communications room within a building. Centralized networking using optical fiber offers users the ability to contain - and even reduce - their operating costs, while simultaneously adding flexibility, control and accessibility to their networks. Centralized cabling designs are sometimes referred to as "collapsed backbone" or "home run" cabling.
Status: Centralized Cabling was elevated from a TSB to a normative annex of 568-B.1 in 2000.

"Centralized Cabling makes it possible for network designers to use optical fiber more cost-effectively and to realize a number of other benefits as well...." Cabling Installation & Maintenance, December 1997 - George Washington University fiber facelift brings horizontal runs to a single location. George Washington University (GWU) in Washington, D.C. has found that creating a faster network within its older buildings can be achieved through a fiber-based collapsed backbone installation.

- Choosing the right fiber LAN architecture
"For years, network planners have recognized the significant performance benefits of optical fiber: low attenuation, high bandwidth and smaller size, to name just a few. But until recently, many of those who sought these benefits in their installations felt they had to force-fit optical fiber into a copper-based design...."
