Polarization Scrambler Module
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 allfiber 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.
