The Cisco Catalyst 6500 10GBASE-EX4 Metro 10 Gigabit Ethernet module fuels the Ethernet evolution by bringing Ethernet technology from the local area network (LAN) to the metropolitan area network (MAN). It supports an extended reach of 10 to 50 km over single mode fiber. It is ideal for building economical, simple and manageable intercampus connections and MAN. By supporting high-bandwidth connections over extended distances, the Catalyst 6500 10GBASE-EX4 Metro 10 Gigabit Ethernet solution enables new applications such as server-less buildings, data center remote mirroring, and disaster recovery, which are key storage networking applications. It also enables high-bandwidth applications such as media-rich content networking and video-rich e-learning.
