Designing and Expanding the Network 2 - 13
Choosing a Network Backbone Cabling Structure
Because of fiber's long-distance capabilities and immunity to noise, 3Com
strongly recommends using fiber as the backbone. You can choose
between two fundamental configuration topologies when connecting your
network backbone using 10BASE-FL Modules in the ONline System
Concentrator:
❑ Star Configuration
❑ Serial Configuration
Star Configuration
Wire your network in a star configuration using an ONline System
Concentrator as the central point in the network. Wiring in a star topology
configuration has two major benefits:
❑ Faults in the cable plant affect only a piece of the network
❑ You can easily expand the size of your network
Figure 2-3 shows an example of a star-wired configuration
