100Base-TX Ethernet Network Guidelines
#
The maximum length of a 100Base-TX cable segment
is 100 meters (328 feet).
#
The maximum number of hubs on a 100Base-TX
segment is one if using Class I hubs and two if using
Class II hubs.
#
The recommended cable type is EIA/TIA Category 5
unshielded twisted-pair.
#
The maximum network diameter is 200 meters (656
feet) when using Class I hubs and 205 meters (672.5
feet) when using Class II hubs.
