Copper-to-Fiber Media Converter

A-CF-01, A-CF-01(SM)

USER’S GUIDE

The TRANSITION Networks ATM (Asynchronous Transfer Mode) copper-to- fiber 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)).

UTP

A-CF-01

Fiber

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.

Status LEDs on the connector side of the media converter provide the following information:

Connectors for like devices

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.

Installation Notes

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

If the ATM media converter fails, determine the answers to the following questions:

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.
