Single Mode/Multimode Media Converter
The protocol-independent TRANSITION Networks media converter, F-SM-MM-05, is
designed for installation EITHER in a 10Mb/s Ethernet environment OR in a 16Mb/s
Token Ring environment.
The F-SM-MM-05 media converter provides an ST fiber RX (receive) and TX (transmit)
connector to 1300nM singlemode fiber-optic cable and an ST fiber RX and TX
connector to 850nM multimode fiber-optic cable. Fiber’s low signal loss and high
resistance to radio frequency noise allow extended distances between devices (up to
2 kilometers for multimode, up to 20 kilometers for singlemode).
The media converter functions in half-duplex mode or, when connected to devices
capable of full-duplex connectivity, in full-duplex mode.
Status LEDs on the connector side of the media converter provide the following
information:

Compliance Information
UL Listed
C-UL Listed (Canada)
CISPR/EN55022 Class A
FCC Regulations
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense.
Canadian Regulations
This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on
the radio interference regulations of the Canadian Department of Communications.
European Regulations
Warning
This is a Class A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.

1. Is the power LED on the media converter illuminated?
NO • Is the power adapter the proper type of voltage and cycle frequency for your AC outlet?
NOTE: Refer to the “Power Supply Requirements” on the back page.
• Is the power adapter properly installed in the media converter and in the outlet?
• Contact Technical Support at [phone]/ (800) LAN-WANS.
YES • Proceed to step 2.
2. Is the multimode fiber Link LED illuminated?
NO • Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to RX and TX ports,
respectively, on the other device.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at [phone]/ (800) LAN-WANS.
YES • Proceed to step 3.
3. Is the singlemode fiber Link LED illuminated?
NO • Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to RX and TX ports,
respectively, on the other device.
• Refer to Tech Tips available at: http://www.transition.com
YES • Contact Technical Support at [phone]/ (800) LAN-WANS.
Troubleshooting the Media Converter
If the singlemode to multimode fiber-optic media converter fails, ask the following:
SINGLEMODE
Fiber Optic Cable Recommended: 9/125 µm singlemode fiber
Fiber Optic Transmitter Power: Average: -16 dBm
Fiber Optic Receiver Sensitivity: Average: -33 dBm
Wavelength: 1300nM
Bit error rate: ≤10-9
Maximum Cable Distance: 5-20 kilometers
MULTIMODE
Fiber Optic Cable Recommended: 62.5 / 125 µm multimode fiber
Optional: 100 / 140 µm multimode fiber
85 / 125 µm multimode fiber
50 / 125 µm multimode fiber
Fiber Optic Transmitter Power: Average: -15 dBm
Fiber Optic Receiver Sensitivity: Average : -33 dBm
Wavelength: 850nM
Bit error rate: ≤10-10
Maximum Cable Distance: 2 kilometers (6,600 feet)
NOTE: This product is NOT a repeater. Therefore, maximum
distances depend on specific characteristics of the installation.
The full distances of BOTH singlemode and multimode fiber
shown MAY NOT be supported in the same installation.
• Connect the power supply cable to the media converter BEFORE
connecting to the outlet.
• Install unit with PSU provided. (Output 9 VDC regulated, 500 mA).
