Fast
Dispersion Analyzer <FDA-2100K>
|
The Fast Dispersion
Analyzer (FDA-2100J) features fast speed and high accuracy for
measuring dispersion parameters of optical fiber and components. With
Alnair Labs proprietary phase detection technology, the instrument can
resolve group delay (GD) or differential group delay (DGD) better than
100fs. The instrument is interfaced with user friendly software which
allows chromatic dispersion (CD), polarization mode dispersion (PMD),
power or insertion loss (IL) and other important polarization
parameters such as polarization dependent loss (PDL) and principle
state of polarization (PSPs) Polarization parameters are measured based
on Jones Matrix Eigen-analysis (JME).
