Selecting a Test Mode
Selecting a Test Mode
Your Optical Spectrum Analyzer gives you different ways to test all your
DWDM systems. Your OSA provides the following test modes:
³ WDM: Allows you to analyze an optical link using an OSA module. By
default, WDM test mode is selected.
³ Drift: Allows you to monitor an optical link for a fixed duration using an
OSA module.
³ DFB: Allows you to characterize a DFB laser source using the OSA
module.
³ Spectral Transmittance: Allows you to characterize the spectral
transmittance of optical components such as filters.
³ 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).
