Configuring your iOLM
To configure the iOLM:
1. From the main window, select the iOLM tab.
2. If two ports are available on your module, select which one to use for
your test. The fiber core is also selected at this point; for C fibers, select
50 m, and for D fibers, select 62.5 m.
3. Select the wavelengths for the next acquisition. The available
wavelengths depend on the iOLM module.
