Product Application and Testing Guide

In the following testing guide a meter refers to an Advanced Fiber Solutions OM120, and a source

refers to an Advanced Fiber Solutions OS420 LED source or OS430 Laser source.

Setting 0 dB loss reference for testing

This is the reference power reading that is created by placing a launch cable between the meter and

the source.

Procedure:

1. Attach launch cable to the output of the source and input of meter.

2. Make sure the output power level from the Source is over -30 dBm.

3. With meter in "dB" mode, hit the zero reference key. When the meter zeros out as illustrated in

the above setup the launch reference power has been stored and the user is now ready to start

testing cables.

4. Once the zero reference power has been set, do not remove the launch cable from the Source as

reattaching it may change the output power level.
