» Product Description

GouMax PSG-220 module (previously LSA-200P) is a customized polarization state controller, used to generate special polarization states for four-state method PDL measurements. GouMax high-speed PDL measurement system consists of a high-speed sweeping tunable laser TLS-1200, a polarization state controller PSG-220 module and and a multi-function power meter module LSA-220 or LSA-800, as shown in Figure 1 below. TLS-1200 provides linearly polarized laser, and LSA-220 measures insertion loss spectra at each polarization state generated by PSG-220 module. GouMax DLL function will calculate PDL based on insertion loss spectra.

PSG-220 module can provide the following functions:

It generates 4 special polarization states from a linearly polarized laser
It synchronizes with TLS-1200 and LSA-220 (or LSA-800)
