Selecting a Test Mode
Selecting a Test Mode
Your module gives you different ways to test all your DWDM systems:

WDM: Allows you to analyze an optical link. By default, the WDM test
mode is selected.

Drift: Allows you to monitor an optical link for a fixed duration.

DFB: Allows you to characterize a DFB laser source.

Fabry-Perot (FP): Allows you to characterize a Fabry-Perot laser source.

Spectral Transmittance: Allows you to characterize the spectral
transmittance of optical components such as filters.

EDFA: Allows you to characterize the performance of an Erbium Doped
Fiber Amplifier (EDFA) using the OSA module in field deployed systems
(NB measurement assumes transmission conditions).
To select a test mode:
1. From the Main Menu, press Mode.
