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.

This section describes:

❑Building a Network (Star Configuration)

❑Building a Network (Serial Configuration)

You can implement either of these configuration topologies when connecting your network backbone using 10BASE-FB modules installed in an ONline System Concentrator.
