PMD5000FIN

ThePMD5000FIN is recommended for general polarization modedispersion measurements. Especially PMD and PDL analysis of fibers and broadband components can be performed with this model. This includes the PMD measurement of passive components (couplers, isolators) and active components (EDFAs and PDFAs). Narrow bandwidth components such as optical filters, Bragg gratings, andOADM, are considerably more challenging to characterize. For narrow bandcomponent manufacturing it is important to assess the PDL in the “wings” of the pass-band (typically around 20dB) to determine if the component meets the isolation requirement between adjacent channels. The PMD5000HDR facilitates this assessment and can increase productionyield. A main advantage of this system is the high dynamic power range ofthe polarimeter. This affords an optimal characterization of the edges of the narrow bandwidth element.
