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.
100BASE-FX Network Guidelines
# In half duplex mode, the fiber optic segment cannot
exceed 412m (1,135ft) in length.
# In full duplex mode, the fiber optic segment cannot
exceed 2km (6562 ft) in length.
