General Photonics’ 4-axis Polarization Scrambler Module uses a breakthrough all-fiber technology to effectively randomize polarization states. Depolarizing by polarization scrambling has many important applications: Scrambling the input polarization can remove measurement uncertainties caused by the polarization sensitivity of the device under test. Performance degradation due to polarization-dependent-gain (PDG) induced in optical amplifiers can be suppressed by scrambling the State of Polarization (SOP). Polarization scrambling can also be used in systems to facilitate and simplify PMD monitoring. Based on a patented, award-winning all-fiber technology, the PCD-003 delivers superior performance with extremely low insertion loss, back reflection and residual phase and amplitude modulation. In addition, the total power consumption is typically less than 10W.
