GeneralPhotonics’ 4-axis Polarization Scrambler Moduleuses a breakthrough all-fibertechnology to effectively randomize polarization states.Depolarizing by polarization scrambling has many importantapplications: Scrambling the input polarization can removemeasurement uncertainties caused by the polarization sensitivity ofthe device under test. Performance degradation due topolarization-dependent-gain (PDG) induced in optical amplifiers can besuppressed by scrambling the State of Polarization (SOP).Polarization scrambling can also be used in systems to facilitateand simplify PMD monitoring. Based on a patented, award-winningall-fiber technology, the PCD-003 delivers superior performancewith extremely low insertion loss, back reflection and residual phaseand amplitude modulation. In addition, the total power consumptionis typically less than 10W.
3. Measured froma photodetector at PCD-003 output using a spectrum analyzer. Apolarizer is placed in front of the photodetector to
convertpolarization modulation to amplitude modulation.
Features:
. No insertionloss
. No backreflection
. Low residualphase and amplitude modulation
. Low powerconsumption
Applications:
. PDG(polarization dependent gain) mitigation
. Polarizationsensitivity elimination
. FacilitatingPMD emulation
. FacilitatingPMD compensation
. FacilitatingPDL measurement
