The DFE-551FX Optical Fibre Fast Ethernet PCI Adapter connects your desktop PC to a fibre network. The adapter plugs into a PCI expansion slot on the PC’s motherboard and transmits data at 200 Mbps full duplex. Supporting advanced functions including VLAN and traffic priority queues, this adapter provides a secure environment to let you run bandwidth-demanding applications, such as IP telephony and video conferencing.

Reliable fibre connection

Fibre optics connectivity makes the adapter suitable for environments with high electro-magnetic interference. The DFE-551FX adapter allows you to connect a workstation or server to a Fast Ethernet switch at a distance of up to 2 km.

Wake-On-LAN power management

The adapter supports Advanced Configuration Power Interface (ACPI) Wake-On-LAN (WOL), allowing your computer to be powered ON/OFF at will from a remote location.

Flow Control to minimise packet loss

When connected to a Fast Ethernet switch that supports Flow Control, the adapter receives signals from the switch regarding buffer overrun during peak usage periods. The adapter then delays transmission until the switch is ready again to accept data again, avoiding data loss.


The adapter supports IEEE 802.1Q multiple Virtual LANs, allowing you to segment the network to smaller domains to improve performance and security. The adapter provides a VLAN table for the following functions: filtering packets by recognising VLAN tags, stripping VLAN tags on receive, and inserting VLAN tags on transmit.

IEEE 802.1p priority queues

With packet prioritisation capability, the adapter allows traffic to be queued as critical and non-critical, permitting your computer to run voice over IP, video-conference and multimedia applications where packets are delivered at best-effort speeds.

RPL and PXE Remote Boot options

Administrators can choose to set up a security scheme for diskless workstations to boot from servers using the traditional Remote Program Load (RPL) or Intel’s Preboot Execution Environment (PXE). Stations with boot ROMs installed on the on-board socket can boot O.S. from NetWare, NT and other servers to run applications designated by the administrator.
