The MPC series are electrically controlled, all-fiber polarization controllers based on fiber squeezing technology.
They are also available with a driver board as the PCD-M02. MPC 3/4X is the third generation of polarization controller, the PolaRITE™ III, with significantly reduced height / size and a special athermal design. The temperature stability is also significantly improved from previous generations. It can be controlled either by a digital or analog signal to obtain any desired polarization output from an arbitrary input polarization state.
PCD-M02 module integrates all-fiber dynamic polarization controller with miniature piezo driver card, so that the SOP of the signal can be directly controlled either by a 0-5V analog control signal or a 12-bit TTL digital control signal. Because there is an on-board HV DC/DC converter, no external high voltage power supply is required.
The card can be configured to accept either a ±12 volt power supply or an external 160-volt power supply. As a polarization controller, the PCD-M02 can convert any input polarization state to any desired output polarization state. As a scrambler, it can randomize the output polarization state. This module offers the low insertion loss, low back reflection, and low activation loss needed for test and measurement applications, combined with the compact size needed for system integration or handheld devices.
