CHAPTER 2: Overview
2. Overview
2.1 Introduction
IEEE 802.3u 100Mbps Fast Ethernet supports two types of media, 10/100Base-TX and 100Base-FX, for network
connection. LFP (Link Fault Pass Through) feature enhances the TP-Fiber Link integrity and conformity.
Either one of TP or Fiber port is in link-fail state, the LFP converter forces the other port to be at link-disabled
state. Comply with IEEE 802.3af, its advanced auto-sensing algorithm enables taking power form IEEE 802.3af
Power Source Equipment (PSE) or Power over Ethernet (PoE) injector. It also supports high safety with short
circuit protection and power-in auto-detection (power from AC/DC power adapter or PSE device).

3. Installing the Converter
3.1 Installing Instruction
CAUTION
Wear a grounding device to avoid damage from electrostatic discharge.
Be sure that the power switch is OFF before you connect the power
cord to the power source.
1. Install the TP media cable to the IEEE 802.3af PSE device or PoE injector. (See Figure 3-1)
2. Install the media cable for network connection.
NOTE
Please make sure that the power of PSE device is turned on, or else the
converter will not work.
3. In case where no 802.3af PSE is available or PSE with PoE power fails, you may install an AC-DC adapter for
a backup solution.
CAUTION
Do not connect PSE TP with PoE and the AC-DC adapter at the same
time.
Verify that the AC-DC adapter conforms to your country AC power
requirement and then insert the power plug.
4. Install the media cable for network connection.

Figure 3-3 S1—Bit 1, 2, 3, 4, 5 configuration and setting
S1-1 TP port mode : AUTO(default) or FORCE
S1-2 TP port speed : 100 or 10 when TP at Force
S1-3 TP port duplex : FDX or HDX when TP at Force
S1-4 LFP : LFP enabled(default) or disabled
S1-5 Fiber port duplex : 100FDX(default) or 100HDX
NOTE
1. S1-2 and S1-3 will take effect only when S1-1 is set at TP-FORCE.
2. S1-5 must be set to 100FDX for Single Fiber Model.
Warning
When TP Nway port is connected to TP 100FDX(force mode) instead of
Nway partner, it will result in 100HDX mode with invalid collision
signal.
Ensure that all network nodes are configured at an identical operation
mode. Improper operation and flow control mode between TP and
Fiber port connections will render the LAN to work poorly.

3.3 Cable Connection Parameter
100Base-X network allows 512-bit time delay between any two node-stations in a collision domain. Switch-based
Media Converter breaks up TP and Fiber segments’ collision domain to extend the cabling distance.
TP Cable Limitations: Cat. 5 and up to 100m
Converter Fiber Cable Limitations:
Multi-mode Half-duplex 412 m
Multi-mode Full-duplex 2 km
Single-mode Half-duplex 412 m
Single-mode Full-duplex 20 km

4. Link Fault Pass Through
This media converter supports link fault pass through (LFP) in TX/FX converter application. Link status on
one port is propagated to the other port to notice the remote nodes. If TP port is unplugged, this converter
stops transmission on fiber port. This causes the remote fiber node link to fail. LED shows the link failure on
both TP and fiber ports. If fiber link fails, this converter restarts auto-negotiation on TP port but always stays in
the link failure state. This causes the remote TP node link to fail. LED also shows the link failure on both TP
and fiber ports. Refer to Figure 4-1 shown below for the normal status when the link succeeds. Also refer to
Figure 4-2 and Figure 4-3 for the erroneous status when TP Cable A, Fiber Cable B or Fiber Cable C fails to
connect.

The LFP (Link Fault Pass Through) function works only when both
two converters own this capability in pairs. Furthermore, both LFP
converters should be supplied only by the same
manufacturer/vender. The connection coming from LFP converters
with odd models or non-LFP converters will cease the LFP function.
