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).
