Introduction
Thank you for choosing the Smart 10/100BASE-TX to
100BASE-FX Media Converter, The Media Converter
introduced here provides one channel media conversion
between 10/100BASE-TX and 100BASE-FX.
Dual-Wavelength Single-Fiber
These types of Single-Fiber modules combine transmit and
receive signals onto one fiber strand using two wavelengths.
This design avoids the budget losses incurred b the
single-wavelength single-fiber technology, and minimizes
any possibility of reflections in the system. The units on
both ends of a link are different. One module uses one
wavelength to transmit and a second wavelength to receive,
while the other module flips that relationship. For this
reason these units are sold in pairs.
About Media Converter
The Smart Media Converter is a network technology
specified by IEEE 802.3 10BASE-T, IEEE802.3u
100BASE-TX, 100BASE-FX standards.

About Link Pass Through
When LLCF is enabled, the ports do not transmit a link
signal until they receive a link signal from the opposite port.
Link loss is “carried forward” to the managed switch or hub
that is sending the link. LLCF can be used for either the
copper or fiber ports.
When LLR is enabled, the fiber port’s transmitter shuts
down if its receiver fails to detect a valid receive link. If
one of the optical conductors is bad, the card with LLR
enabled will return a no link condition to its link partner.
LLR is used to detect link problems only on the fiber port.

Installation
This chapter gives step-by-step installation instructions for
the Smart Media Converter.
Selecting a Site for the Equipment
As with any electric device, you should place the
equipment where it will not be subjected to extreme
temperatures, humidity, or electromagnetic interference.
Specifically, the site you select should meet the following
requirements:
1. The ambient temperature should be between 32 and
104 degrees Fahrenheit (0 to 40 degrees Celsius).
2. The relative humidity should be less than 90 percent,
non-condensing.
3. Surrounding electrical devices should not exceed
the electromagnetic field (RFC) standards for IEC
801-3, Level 2 (3V/M) field strength.
4. Make sure that the equipment receives adequate
ventilation. Do not block the ventilation holes on
each side of the switch or the fan exhaust port on
the side or rear of the equipment.
5. The power outlet should be within 1.8 meters of the
switch.

Sliding Switch
There is a sliding switch for the setting on copper and fiber
port. Refer to the table below for more details.

Installing in a Chassis
The Converter can be fit into any of the expansion slots on
a special designed chassis.
Unscrew and pull out the
media converter board
First, install the converter onto a carrier supplied with the
chassis:
Step 1- Unscrew the carrier from the desired expansion
slot on the chassis.
Step 2- Remove the screw on the converter as shown
below.
Step 3- Fit the converter onto the carrier and use the
screw to secure it.
7

Management the Media Converter
The optional Management Chassis that can control this
Smart Media Converter through the management system,
this Smart Media Converter can be controlled through Web
Browser, SNMP management utility and terminal
emulation program.
The Management Chassis will detect the default reset on
the DIP switches and display out the status, also the
Management Chassis can control the function through the
management system.
Through the optional Media Converter
Chassis System via Management Module, you
can control the setting of this Smart Media
Converter.

Dual Wavelength Single Fiber
The converter combine transmit and receive signal onto one
fiber strand using two kind of wavelength. The units on
both ends of a link are different. One module uses one
wavelength to transmit and a second wavelength to receive,
9

while the other module flips that relationship. For this
reason these units are sold in pairs.
When using a converter that the TX (transmit) is 1310nm
and the RX(receive) is 1550nm, then the other end need to
have a combination of converter that the TX(transmit) is
1550nm and the RX(receive) is 1310nm.
The TX needs to connect to the other end’s RX with the
same wavelength.

loss the link, the converter’s fiber will disconnect the link
of transmit.
The switch 5 is to enable or disable the LLR function of the
media converter.

LLCF (Link Loss Carry Forward)
When a device connected to the converter and the TP line
loss the link, the converter’s fiber will disconnect the link
of transmit, so that the other ends will know that there is a
linkage error on this end. And when the Fiber line loss the
link, the converter’s TP will disconnected, and the other
end will know that there is linkage problem exist.
The switch 6 is to enable or disable the LLCF function of
the media converter.
