Connectivity Rules
When adding hubs (repeaters) to your network, please follow the
connectivity rules listed below for Ethernet, Fast Ethernet, and Gigabit
Ethernet. However, note that because switches break up the path for
connected devices into separate collision domains, you should not include
the switch or connected cabling in your calculations for cascade length
involving other devices.
1000 Mbps Gigabit Ethernet Collision Domain
Note:
Although maximum cable length for 100BASE-FX fiber depends
on the duplex mode, the maximum length for 1000BASE-X fiber
is the same for both half and full duplex.
