Installation
The default switch settings (all switches in the UP position) will
work for most installations.
These are the steps required to configure the Perle Fast Fiber to
Fiber media converter:
1. Set the DIP switch settings (optional).
2. Install and connect the fiber cable to port MM1.
3. Install and connect the fiber cable to port MM2/SM2.
4. Power up the media converter.
DIP Switches
The DIP switches are accessible through the opening in the side
of the enclosure
Note: All switch changes take effect immediately and will result in
a link reset on both fiber ports.

DIP Switch Settings
Link Mode (Switch 1)
Switch Position Mode
Up (default)
Down
Link Pass-Through Mode
Standard Mode
Link Pass-Through: In this mode, the link state on one fiber
connection is directly reflected through the media converter to the
other fiber connection.
For example, if a Far End Fault (FEF) indication is received on
port MM1, the media converter in turn sends a signal to turn off the
transmitter on port MM2/SM2. When the Far-End Fault indication
is cleared the transmitter is then turned back on.
Standard Mode: In this mode, the links on the fiber side can be
brought up and down independently of each other. A loss of link
on either fiber connection can occur without affecting the other
fiber connection.
Far End Fault (Switch 2)
Switch
Position
Mode
Up (default)
Down
Enabled
Disabled
Enabled: If the media converter detects a loss of fiber signal on
the fiber receiver, the media converter will immediately send a
FEF on the fiber link. This, in effect, notifies the fiber link partner
that an error condition exists on the fiber connection.
If the remote media converter is set up for Far End Fault (FEF)
and the local media converter is set up with Link Pass-Through, a
loss of fiber link on either the transmit or receive link will be
passed through to the end fiber connection.
Disabled: Far End Fault indications are not transmitted regardless
of the condition of the receive signal on the 100BASE-FX fiber
connection.

Note: This switch needs to be set to either generate or detect the
FEF signal.

Sequence of Events
1. Media Converter A loses fiber connection (RX) on MM2/SM2.
2. Media Converter A sends FEF on transmitter (TX) MM2/SM2.
3. Media Converter B detects loss of fiber link on receiver RX –
MM2/SM2.
4. Media Converter B turns off transmitter (TX) on MM1/SM1.
5. Media Converter A MM1 is not affected

Mode
Up (default)
Down
Disabled
Enabled
Disabled: The loopback feature is disabled. This is the normal
position for regular operation. The switch must be set to this
position in order for data to pass through the media converter.
Enabled: This is a test mode. All data received on the receive
(RX) fiber connection on port MM1 is looped back to the transmit
(TX) fiber connection.
Note: Only one fiber interface can be in loopback at a time.
Remote Loopback Fiber 2 (Switch 4)
Switch
Position
Mode
Up (default)
Down
Disabled
Enabled
Disabled: The loopback feature is disabled. This is the normal
position for regular operation. The switch must be set to this
position in order for data to pass through the media converter.
Enabled: This is a test mode. All data received on the receive
(RX) fiber connection on port MM2/SM21 is looped back to the
transmit (TX) fiber connection.
Note: Only one fiber interface can be in loopback at a time.

Installing the Duplex Fiber Cable
Locate a 100Base-X compliant duplex (2 strands) fiber cable with
appropriate connectors.
Connect the fiber cables from one media converter to the other
media converter/switch/fiber device ensuring that the RX and TX
are reversed at the opposite end.
Installing the Simplex Fiber Cable
Locate a 100Base-X compliant simplex (1 strand) fiber cable with
appropriate connectors.
Connect the fiber cable from one Media Converter Module to
another Media Converter/switch/fiber device.
Powering up the Media Converter
1. Connect the Perle supplied power adapter to the media
converter.
2. Turn on the power at source.
3. Check that the PWR LED light is lit and on solid.

Troubleshooting
General
•
Ensure power is supplied to the media converter – use of the
supplied power adapters is highly recommended.
Ensure both devices on either end of the fiber are compatible.
If using a simplex fiber connection, ensure that you have both
an Upstream (U) and Downstream (D) media converter.
Ensure all cabling is of the correct type and is in good working
condition.
•
•
•
For duplex fiber connections, ensure the RX and TX has been
reversed between the two media converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, this procedure is recommended for troubleshooting.
Method 1
1) Set the Link mode to Standard (SW1 – Down) on both media
converters. Leave all other switches in the Up position.
2) Connect the near end device to port MM1, the LK1 LED
should be lit to indicate a good fiber connection. If the LK1
LED is not lit, then check the fiber cable and the attached
device.
3) Repeat step 2 for port MM2/SM2.
4) Return units to desired configuration.
Method 2:
The fiber connection can also be verified by configuring the remote
media converter for loopback mode. The link LEDs on both media
converters should be lit. Data should pass through the local
converter, over the fiber connection to the remote media
converter. At the remote media converter, the data will be looped
back and passed back through the fiber.
