Can a component pass IL inspection and still fail in the real system?
A component may pass a basic insertion loss test while still exhibiting issues caused by wavelength-dependent loss (WDL), polarization-dependent loss (PDL), back-reflection, or spectral drift. For passive components such as filters, AWGs, couplers, and isolators, understanding performance requires more than a single measurement value.
Our latest application overview explores key techniques for component characterization.
