As Cisco's premier modular multilayer switch, the Catalyst 6500 series delivers secure, converged services from the wiring closet to the core, from the datacenter to the WAN edge. Designed for Enterprise datacenter, distribution and core deployments, the high-density four port 10GE module is fully 802.3ae standards compliant using industry-standard modular optics to meet a wide range of station to station deployment lengths. Supporting 40Gbps interconnection to the Cisco Catalyst 6500 Supervisor Engine 720's integrated 720Gbps switch fabric, this module uses accelerated Cisco Express Forwarding (dCEF) delivering peak system throughput of up to 400Mpps. Up to 32 10 Gigabit Ethernet ports can be deployed in a 9 slot Catalyst 6509 chassis.
