The Cisco Catalyst 6500 10GBASE-ER Serial 1550nm 10 Gigabit Ethernet module fuels the Ethernet evolution by bringing Ethernet technology from the local-area network (LAN) to the metropolitan-area network (MAN). Cisco Catalyst 6500 10GBASE-ER Serial 1550nm module is compliant with the IEEE 802.3ae standard and supports an extended reach of up to 40 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 Cisco Catalyst 6500 10GBASE-ER Serial 1550nm 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.The Serial 1310nm 10 Gigabit Ethernet module (up to 10 km over single-mode fiber) together with the Serial 1550nm 10 Gigabit Ethernet module (up to 40 km over single-mode fiber1) give a Cisco Catalyst 6500 10 Gigabit Ethernet solution that enables customers to implement new high-bandwidth applications such as storage networking, media-rich content networking, and video-rich e-learning over varying distances.
