Topology Rules

4-3

One Class I Repeater A total network span of 260.8 meters (combined UTP and ﬁber cabling) is allowed in single-Class I hub topologies (one hub stack per wiring closet with a ﬁber run to the collapsed backbone). For example, you could use a

160.8-meter ﬁber downlink from the hub to a router, bridge, or switch with a 100-meter maximum UTP run from the hub to the desktops. (See Figure 4-2.)
