In a repeater environment, 100BASE-TX only allows a single layer of
cascaded hubs.
Switching hubs, such as LantronixÕs LSW8FA, may increase the
network diameter for 100BASE-TX networks by buffering data packets.
Each port can be connected to a separate LAN segment, each with a
maximum diameter of 205 meters, thereby increasing the overall
100BASE-TX network diameter.
Not only does 100BASE-TX have a different data transmission scheme,
it also has different cabling requirements. As noted above, 100BASE-TX
requires data-grade (Category 5) UTP cable.
Some installations have Category 5 cabling but do not have wall outlets
and wiring closet punch-down blocks that meet Category 5 require-
ments. 100BASE-TX requires that all wiring and accessories meet
EIA/TIA 568B specifications for proper operation. When wiring a
100BASE-TX network, make sure that the entire cable plant meets
specifications.
