You can extend the 100BASE-T network topology further by
interconnecting the switches using fiber links. Interconnecting two
switches creates a network that contains four separate collision
domains. The overall network topology grows while each collision
domain can be modeled after the extended collision domains
illustrated in previous two illustrations.
The next illustration shows how two separate 100BASE-T networks,
each supporting different workgroups in different physical locations,
are interconnected using a 2-km fiber link.
