Multifunction Polarization Controller—PolaMight™

MPC-201
Controlling the state of polarization (SOP) of an optical signal has
never been easier: This multifunction polarization controller has four
operational modes for complete polarization control: variable rate
polarization scrambling, manual polarization adjustment, polarization
modulation, and externally triggered random SOP generation. Four
different polarization scrambling methods enable the SOP to a) trace
out a spiral pattern about a static or rotating axis with a nearly uniform
SOP variation rate for system stress tests (Tornado scrambling); b)
generate a continuous trace with a Rayleigh distribution of SOP
variation rate, for emulation of the SOP variation in a fiber link
(Rayleigh scrambling); c) generate a continuous trace with uniform sphere coverage for PDL measurement
(Triangle scrambling); or d) evenly cover the Poincaré sphere with discrete, random points at a uniform rate
(Discrete scrambling). In the SOP modulation mode, each polarization control axis can be selectively
controlled with a sine, square, or triangle wave of user defined frequency and amplitude. Each polarization
control axis can also be controlled manually, by setting the input voltage either from the front panel controls
or through a remote control interface. In externally triggered scrambling mode, discrete, random SOPs are
generated in response to a trigger input, a feature desirable for recirculating loop applications or other
applications requiring synchronization with other devices. Finally, the MPC-201 can emulate the Agilent
11896A polarization scrambler function, allowing it to act as a plug-in replacement for this popular but
discontinued device, while offering many more advanced features. PolaMight puts the user in control.
