General Photonics’ PCD-104 polarization scrambler uses a breakthrough patented all-fiber technology to effectively randomize polarization states. Specifications include low insertion loss and low back reflection as well as minimal phase and amplitude modulation. The instrument can be used in automatic test systems under remote control through digital interface options.
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.
The PCD-104 polarization scrambler delivers superior performance, including extremely low insertion loss, back reflection, and residual phase and amplitude modulation.
