MPC-201 Polarization Controller

980-1620 nm; Multiple Polarization Control Modes; IL <0.6 dB; PDL <0.1 dB; PMD <0.2 ps; AL <0.1 dB; RL >50 dB

Controlling the state of polarization (SOP) of an optical signal has never been easier – Lunas MPC-201 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. The MPC-201 polarization controller puts the user in control.
