General Photonics’ Polarization Scrambler uses a breakthrough all-fiber technology to effectively randomize polarization states. Depolarizing by polarization scrambling has many important applications. Scrambling the input polarization can eliminate measurement uncertainties caused by the polarization sensitivity of the testing device.
Performance degradation due to polarization dependent gain (PDG) induced in optical amplifiers can also be suppressed by polarization scrambling. In addition, polarization scrambling can be used in systems to facilitate and simplify PMD monitoring.
Based on a patented, award-winning all-fiber technology, the PCD-104 delivers superior performance, including extremely low insertion loss, back reflection, and residual phase and amplitude modulation.
