Optical Fiber Fast Ethernet Adapter
D-Link's DFE-560FX Optical Fiber Fast Ethernet Adapter connects your desktop PC to a reliable fiber network. The card plugs into a PCIe expansion slot inside your PC, transmitting data at 200 Mbps full-duplex. Supporting advanced functions including traffic priority queues and VLAN, this adapter provides a secure environment to let you run bandwidth-demanding applications, such as IP telephony and video conferencing.
Reliability and Performance
The DFE-560FX card allows you to establish a secure fiber link for your PC. It can be used to set up a workstation or a server with a direct fiber connection to a Fast Ethernet switch. Capable of running at 200 Mbps full-duplex, this card serves well in a high electromagnetic interference environment, providing data transmission over a cable distance of up to 2 km to the switch. Along with PCI Express v1.1 bus master operation, this card provides the highest possible performance. The bus master transfers data directly between the card and the host at multi-megabits per second, bypassing the host CPU to alleviate its workload.
Flow Control to Minimize Packet Loss
The card's embedded flow control feature provides a means to protect against possible data loss during transmission on the network. When connected to a Fast Ethernet switch that supports flow control, the card receives signals from the switch regarding buffer overrun during peak usage periods. It then delays transmission until the switch is ready again to accept new data.
VLAN to Improve Performance and Security
The card supports IEEE 802.1Q multiple Virtual LAN, allowing you to segment the network to smaller domains for improved performance and security. Dissemination of broadcast and unnecessary computer-to-computer packets can be restricted to reduce extraneous traffic. The card provides a VLAN table for the following functions: filtering packets by recognizing VLAN tags, stripping VLAN tags on receive, and inserting VLAN tags on transmit.
PXE Remote Boot Option
Remote boot is available as an option. Administrators can choose to set up a security scheme for diskless workstations to boot from servers using Intel's Preboot Execution Environment (PXE). Stations with boot ROMs installed on the onboard socket can boot an OS such as Windows, Linux, and NetWare installed on servers to run applications designated by the administrator.
