Cisco Systems offers a family of Fast Ethernet (FE) port adapters optimized for the specific requirements of campus and enterprise backbones and data centers. The Cisco FE port-adapter options provide either one or two ports of 100BaseTX (copper) or 100BaseFX (fiber) Fast Ethernet ports per adapter. Each port can be configured for half- and full-duplex operation.
Fast Ethernet single-wide port adapters are available in six models for the Cisco 7200, 7300, 7400 and 7500 Series routers.
