Measuring Insertion Loss
Measuring Insertion Loss
To ensure accurate measures for the insertion loss of a fiber-optic
component, use a light source (FLS-2100) and a PM-1600 Power Meter.
To measure insertion loss,
1. Using two appropriate test jumpers and a bulkhead adapter, connect
the source to the power meter as shown below. This setup will be used
to record a reference value.
2. Adjust the source and power meter to the appropriate wavelength.
3. Activate the source and select a suitable power output.
IMPORTANT
The absolute power output value is not particularly important when
measuring insertion loss. However, it is very important that the
power level used for taking the reference measurement be identical
to the power level used during the insertion loss measurement.
