Understanding the General Rules
As part of your network design, it is important to consider your network
size. For instance, is the network (end-to-end) 100 meters, 1000 meters,
4000 meters, or more? What are your plans for expansion? Your answers
play a role in how you configure your network. For example, once the
network expands beyond a certain size, you need to add a bridge or other
internetworking device.
This section describes general rules for configuring an Ethernet network
using fiber as the backbone medium. It also provides rules to ensure that
your network configuration conforms to distance limitations imposed by
Ethernet and networking equipment.
