With regards to network security, one of the best ways to avoid unauthorized access into your network is to implement a fiber-based topology. While controlled access at the desktop, virus protection, and other proprietary solutions provide software-based security, fiber cabling currently provides the best possible protection available against physical network tapping. In addition, fiber cabling is also immune to electromagnetic interference, which can disrupt network transmission. As an organization grows, so must the network. When the system moves beyond a simple LAN to a campus-wide, metropolitan or global network, the topology must be able to expand and fit the new requirements.
Some topologies have inherent distance limitations.
This will leave room to expand the network without the additional cost of replacing your existing infrastructure. Interoperability Network solutions based on proprietary hardware and software really aren't solutions at all. Such proprietary offerings often do not gain widespread acceptance and are difficult to support. So it's crucial to choose an established infrastructure that is standards-based. In the long run, you'll receive better interoperability between platforms, components, and protocols.
