The PCD-005 Polarization Scrambler Module rapidly randomizes the instantaneous polarization state of output light to achieve a time-averaged depolarization effect. It includes circuitry to cover several wavelength bands, improve temperature performance, and add remote control capability.
The PCD-003/005 polarization scramblers combine a fiber squeezer polarization controller with specialized driver electronics to achieve uniform Poincaré sphere coverage in a few ms. Because they use the resonance frequencies of the polarization controller, the scrambling rate is fixed. Because of the all-fiber construction, they have low insertion loss and low back reflection as well as minimal phase and amplitude modulation.
The PCD-005 allows the user to enable/disable the scrambler and change the wavelength band setting from the front panel or via remote control. It is the module counterpart to the PCD-104 instrument.
