Cisco WS-X6704-10GE Network Switch Module Networking

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.

4-Port 10 Gigabit Ethernet Fiber Module
The 4-port 10 Gigabit Ethernet fiber module has no oversubcription and is designed for deployments in which line rate is important. It provides up to 34 10 Gigabit Ethernet ports in a single Cisco Catalyst 6509 chassis and 68 10 Gigabit Ethernet ports in a VSS.

Applications
4-port 10 Gigabit Ethernet fiber module: Core, interbuilding connections, POPs, WAN edge, and MAN connections, where no oversubscription and medium to low 10 Gigabit Ethernet density is required
