is to be connected. Additional backbone cables may be run to provide backup for
the primary cables or to provide closure of a ring. Backup cables or cables to com-
plete a ring are an integral part of the backbone hierarchy.
By the way, nothing in this implies that a backbone is either fiber optic or cop-
per, as either one may serve your needs well. Keep in mind that the allowable dis-
tances between closets in TIA-569-B exceed the distances for copper wire
10/100/1000BaseT or Token-Ring, set without reference to a specific LAN topology.
However, the use of fiber-optic cable can extend your cables to the limit of the TIA
standard.
