LFX2 
Fast Ethernet
Extender

The Lantronix LFX2 Fast Ethernet Extender is a
10/100 bridge which can be used in a number of
ways in an Ethernet environment:

1.

Conversion between 10 Mbps Ethernet and
100 Mbps Fast Ethernet - allows devices of
one speed to be connected to a segment
supporting the other speed

2.

Cable extension for 100BASE-T networks -
regenerates packets and therefore supports
network diameters greater than those possi-
ble if only using hubs or repeaters

3.

Collision domain separation - reduces
unnecessary traffic on each segment which
allows for greater throughput 

The LFX2 has 2 10/100 RJ45’s, capable of
autosensing both speed and half/full duplex
operation. Each LFX is a self-learning bridge,
capable of supporting 8,192 addresses and per-
forming wirespeed filtering and forwarding. All
bridging functions are automatic - no manage-
ment software is required. The LFX2 conforms to
the IEEE 802.3 10BASE-T and IEEE 802.3u
100BASE-T standards.
