ANSI/TIA-568-C.0 and C.1: Optical Fiber Supportable Distances
ANSI/TIA-568-C.0: Fiber Optic Cabling Guidelines: Centralized Cabling
Single tenant users of fiber optic data networks can avoid distributed electronic equipment by using the centralized cabling method.
Centralized electronic equipment and cabling reduces cost and complexity, and maximizes transmission performance. Extended dis-
tances are permitted using these methods. The interconnect method is most flexible and is the preferred choice.

For the simplest design, the HC on each floor receives a
home run backbone cable from the MC in the ER. This
represents a star topology. Multiple buildings in a campus
form a Hierarchical star topology
from the central MC
facility. Codes require non-fire rated OSP backbone cable
to extend no longer than 50 ft into the building without
conduit. Firestopping is required for wall or floor penetra-
tions of backbone sleeves or slots.
Properly support vertical
cables, and do not exceed manufacturer’s vertical rise limits.
Consider diverse and redundant cable paths for disaster
recovery. If possible, vertically align TR’s on multiple floors to
simplify the backbone pathways.
NOTE: See page N14 through N16
for Pull Forces, Minimum Bend Radius, and Installation Practices.
