The N7788C optical component analyzer provides both polarization control and analysis functions in one instrument for flexible laboratory use. The N7788C is especially used in combination with a tunable laser for measuring how an optical component changes the SOP of a signal. This measurement uses the unique single-sweep polarization dependent method to determine the parameters polarization mode dispersion (PMD) or differential group delay (DGD) and polarization dependent loss (PDL), based on a generalization of the standardized Jones Matrix Eigenanalysis method (JME).
For these spectral measurements of polarization dependent loss and dispersion, the N7788C is combined with a tunable laser and a new N7700 software engine. The LS engine, part of the Photonic Application Suite, now supports these measurements of wavelength-dependent DGD and PMD. This mode can be licensed with N7700103C PMD.
Parameters provided by this measurement include:
- Jones matrices
- Mueller matrices
- 2nd-order PMD (depolarization + PCD)
General polarimeter and polarization control functions of the N7788C are supported by the built-in user interface.
The instrument comes in a compact form factor of just one rack unit height, with LAN and USB interfaces.
