The Cisco Catalyst 6500 Series Switches offer a variety of 10 Gigabit Ethernet modules to serve different needs in the campus and data center for enterprise, commercial, and service provider customers: the Cisco Catalyst 6500 16-port 10 Gigabit Ethernet Copper Module, 16-port 10 Gigabit Ethernet Fiber Module, 8-port 10 Gigabit Ethernet Fiber Module, and 4-port 10 Gigabit Ethernet Fiber Module. The copper module supports RJ-45 connectors and provides operational distance of up to 100m over Category 6, 6A, and 7 type cabling. The fiber modules support pluggable optics and provide operational distances of up to 80 km over single-mode fiber and 300m over multimode fiber.
16-Port 10 Gigabit Ethernet Fiber Module
The 16-port 10 Gigabit Ethernet fiber module (Figure 2) provides up to 130 10 Gigabit Ethernet ports in a single Cisco Catalyst 6509 chassis and 260 10 Gigabit Ethernet ports in a VSS and is designed for LAN campus aggregation and data center access, where fanout and port density are very important. It consists of 4 port groups of 4 ports each. Users can operate each port group in either oversubscription mode (2 to 4 ports used per port group) or performance mode (1 port used per port group), providing the flexibility to use some ports for connection to servers in performance mode and others for uplinks to wiring closets in oversubscription mode. In performance mode, up to 4 10 Gigabit Ethernet ports can be used to create a virtual switch link in a VSS.In addition, the 16-port 10 Gigabit Ethernet module has reduced power consumption. It uses half the power per port of the 8-port 10 Gigabit Ethernet module, providing substantial power savings to the customer.
