Measuring Optical Switch Port Insertion Loss
The insertion loss (IL) of any switch port can be measured using a light
source, power meter, and the IQS-9100/9100B Optical Switch.
To measure optical switch port insertion loss:
1. Connect the light source output port to the power meter detector port
using two test jumpers linked with a bulkhead connector.
2. Store the power reading obtained as a reference value in the power
meter.
