10BASE-T Twisted Pair Ethernet Network Design
Unshielded Twisted Pair (UTP) wiring is found in most business
environments. For this reason, IEEE adopted a set of standards for
implementing this cost effective wiring into its own Ethernet category.
Designing a 10BASE-T Ethernet is much like designing a Fiber Optic
network, as both media are point-to-point media. A 10BASE-T network is
configured in such a way that the resulting topology is a star. A multi-port
repeater is used in a central location, such as a wiring closet, with twisted
pair segments going to the workstation locations. Each segment is a
maximum of 200 m in length, with no other taps or branches allowed. As
with all un-bridged Ethernet networks, the maximum signal path is 4
repeater hops and 5 segments. Refer to Figure 7-12.
