High-density fiber-based 100-Mbps Fast Ethernet modules offer enterprises and military operations the ability to deploy fiber to the desktop to maximize security of their network. The Cisco Catalyst 6500 100BASE-FX modules also can be deployed in areas where customers need long-distance (greater than 550m and up to 2 km) connection over existing multimode fiber where Gigabit Ethernet is not an option.
