1. Introduction
The 10/100BASE-TX to 100BASE-FX media converter series provides a media conversion allowing
high-speed integration of fiber optic and twisted-pair segments. With 10BASE-T and 100BASE-TX
support, the converters provide seamless translation between Ethernet and Fast Ethernet networks. A
complete set of LEDs allows for quick status verification. Because of 802.3af compliance, the
converters can draw the power via Cat.5 cable connected to a PoE PSE switch or mid-span injector in
addition to being powered by typical external power adapter. This feature makes the converter ideal for
remote areas of a network without AC power outlets.

1.4 Special Functions
1.4.1 Auto MDI/MDI-X Function
This function allows the TP port to auto-detect the twisted-pair signals and adapts itself to form a valid
MDI to MDI-X connection with the remote connected device automatically.
1.4.2 Auto-negotiation Function
When TP port is set on Auto-negotiation mode (SW1:ON), it is featured with auto-negotiation function
and full capability. It performs a negotiation process for the speed and duplex configuration with the
connected device automatically when each time a link is being established.
1.4.3 Far End Fault Function
The FX port is facilitated with this function, which conforms to IEEE 802.3u 100BASE-FX
specifications. When the FX port detects a link failure on its receiving circuitry, it will send out an
FEFI (Far End Fault Indication) signal to the remote connected device to indicate a remote fault is
detected. It also is capable to receive FEFI signal sent from the remote link partner. Upon receiving an
FEFI signal, it indicates a link failure occurred on the transmitting path. This function allows the
converter to report a fiber link fault even when a link failure occurred on transmitting fiber cable.

12
1.4.4 Link Fault Pass Through Function
When this function is enabled, a link fault detected on the TP port will force a link down on the FX
port. Similarly, a link fault detected on the FX port will also force a link down on the TP port. As
illustrated in the following figure, this function allows to pass TP link fault to the remote link partner
and makes the converter like a TP cable extender.

13
1.4.5 Remote TP Port Monitoring Function
The converter provides LED indicators labeled RTP LINK/100M/FDX to display the TP port status of
its remote link partner on FX port. As illustrated in the following figure, the remote MC must be
enabled for periodical status report.
1.4.6 Loop Back Test Function
As illustrated in the following figure, the local MC starts a loop back test by pressing the loop back test
button. It sends test frames from its FX port to the remote MC. The remote MC forwards the received
test frames back to local MC from its FX port. The local MC verifies the loop back test frames and
display the test result on RTP LINK/100M/FDX LEDs. This function can help installer to check the
full path from a local MC through fiber to a connected remote MC and back to local MC.

2. Installation
2.1 Unpacking
Check that the following components have been included:
Installation guide (or contained in the product CD)
The 10/100 Media Converter
If any item is found missing or damaged, please contact your local reseller for replacement.
2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the product, observe the
following precautions.
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or
contact your trained service provider:
- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
Operate the product only from the type of external power source indicated on the electrical ratings label. If
you are not sure of the type of power source required, consult your service provider or local power company.

15
2.3 Mounting the Device
Desktop Mounting
The media converter can be mounted on a desktop or shelf. Make sure that there is proper heat
dissipation from and adequate ventilation around the device. Do not place heavy objects on the device.
Wall Mounting
The media converter also can be mounted on a wall. On bottom of the device, wall mounting hole is
provided for wall mounting.
Din-rail Mounting
For a Din-Rail chassis, the media converter can support mounting on a Din-Rail. An optional Din-Rail
bracket, KC-3DR can be purchased separately. Consult your dealer for details. The following figures
show an example after bracket installation:

16
2.4 Powered by PoE over Cat.5
Power supply by a Mid-Span PoE Injector
The following figure illustrates the converter is powered by the PoE delivered from a remote mid-span
PoE injector over Cat.5.
Power supply by a PoE PSE Switched Port
The following figure illustrates the converter is powered by the PoE delivered from a remote PoE PSE
switch over Cat.5.
Note:
1. The Cat.5 used can be the standard Cat.5 cable for Ethernet connection.
2. Check the power LED on the converter to see whether the power is received on the Cat.5.
3. For the compatibility, the remote PoE PSE used must be IEEE 802.3af compliant.

17
2.5 Powered by External Power Adapter
The converter can support being powered by an external power adapter as an alternative when PoE
power is not available on Cat.5. Before you begin the installation, check the AC voltage of your area.
The AC power adapter, which is used to supply the DC power for the unit should have the AC voltage
matching the commercial power voltage in your area.
The AC Power Adapter Specifications
AC input power: AC power voltage of your area,
Rated input options -
AC120V/60Hz, AC230V/50Hz,
AC100V/50-60Hz, Rated AC240V/50Hz
Rated output - DC7.5V 500mA min.
Steps to apply the power to the converters are:
1. Connect power adapter DC plug to the DC input jack located on the back of the converter before
connecting to the AC outlet.
2. To ensure against accidental disconnection, tie the DC cable with the cable tie located the back of
the converter.
3. Connect the power adapter to the AC outlet.
4. Check Power LED indication.

Since the WDM single fiber media converters use different wavelengths for transmission and receiving
respectively, the link partner device located on the remote end of the single fiber should match the
wavelength used on the single fiber converter.
