6DFE853...01

Printed in TaiwanThis guide provides basic information for
installation and use of D-Link Fast Ethernet transceiver models
DFE-853 and D FE-854.

Intro duction

D-Link Fast Ethernet transceiver models DFE-853 and DFE-854
represent the best value on the market. These transceivers are IEEE

802.3u compliant and support both half- and full-duplex operation.
Diagnostic LEDs are on the front, with the cabling connectors, for
maximum visibility.
Transceivers provide additional media options for Fast Ethernet
hubs, switches, bridges and routers equipped with MII ports. A
DFE-853/DFE-854 transceiver is recommended for a network
device with a built-in MII connector.

The DFE-853 MII to 10BASE-T or 100BASE-TX transceiver has
the Auto-negotiation function, which means the transceiver
automatically adjusts itself to the Ethernet speed (10 or 100) and
duplex mode (half or full) of the attached segment. W hen two auto­negotiation devices with multiple capabilities

are linked together,

they fi nd t he i r optimum co m m on mo d e of ope r a t ion .

9

The DFE-854 MII to 100BASE-FX multimode fiber transceiver
supports transmissi on distances up to 2 kilometers (full-duplex) and
412 meters (half-duplex). The DFE-854 transcei ver only operates at

100Mbps

.

transceivers are listed in the followi ng table

For the DFE-8533: set the switch F to the OFF position if the
attached device, such as a switch or a NIC card, has Auto­negotiation capability or can communicate in full-duplex mode; set
