Transition Networks A-CF-01SM, A-CF-01 User Manual
The TRANSITION Networks ATM (Asynchronous Transfer Mode) copper-tofiber media converters connect twisted-pair copper cable network segments to
multimode fiber optic cable network segments (using A-CF-01) OR to
singlemode fiber optic cable network segments (using A-CF-01(SM)).
The ATM media converters provide network connection using an RJ-45 twistedpair ATM connector and a set of RX (receive) and TX (transmit) SC-type ATM fiber
connectors. NOTE: Effective cable distances are determined by ambient RF noise
and by signal loss in the cable. The fiber connection, with low signal loss and high
resistance to radio frequency noise, allows extended distances between ATM
devices. Twisted-pair runs are best kept as short as possible to preserve signal
integrity.

Compliance Information
UL Listed
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.

Straight Through/Crossover Cable Requirements and Pin Specifications
The two active pairs in an
ATM network are pins 1 & 2
and pins 7 & 8. Use only
dedicated wire pairs (such as
blue/white & white/blue,
orange/white & white/orange)
for the active pins.
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 (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the TX Activity LED illuminated?
NO
• Check UTP cables for proper connection and pin assignment. (See above.)
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 3.
3. Is the Fiber Activity 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 100BASE-FX device.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
• KEEP TWISTED-PAIR RUNS AS SHORT AS POSSIBLE.
• 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).
Troubleshooting the Media Converter
Installation Notes
If the ATM media converter fails, determine the answers to the following questions:
Be certain that the twisted-pair cable is configured
correctly (straight through or crossover) for site. Cable
connections between an ATM switch and the media converter must
be configured as straight through. Cable connections between the
media converter and a NIC must be configured as crossover.
The physical characteristics of the media cable must meet or exceed the
specifications: ATM UNI 3.1 #AF-PHY-0015
Maximum number of media converters in series: 2
