- The system likes very high speed (200 Mbps and up), low cost fiber in a
- campus environment. The idea is that fiber drops in price faster than
- high speed memory, so its cheaper to just add more fiber as bandwidth needs
- increase, the switch itself is not the costly item. Now all the LAN hubs
- connect to the mesh of fiber providing speed of light transfer.
