Technical Information

Fast Ethernet Wiring
100BASE-TX Specification: The 100BASE-TX specification supports 100
Mbps transmission over two pairs of category 5 twisted-pair Ethernet (TPE)
wiring. One pair is for transmit operations and the other for receive operations.
Segment lengths are limited to 100 meters with 100BASE-TX for signal timing
reasons. This complies with the EIA 568 wiring standard.
Fast Ethernet Hub and Switches
The two basic types of hubs are shared hubs and switching hubs. Intel PRO/
100+ adapters can be used with either type of hub for 10 Mbps. At 100 Mbps,
a TX hub or switch is required.
