Overview
The MPC series are electrically controlled, all-fiber polarization controllers based on fiber squeezing technology, packaged in a low-profile 0.63 inch high enclosure. They are available with 3 or 4 fiber squeezers. Either version can generate any polarization state on the Poincaré sphere; the 4X version provides an extra degree of freedom for reset-free operation and polarization scrambling.
The all-fiber design has low insertion loss and minimal activation loss and operates over a wide wavelength range. An athermal package design provides temperature stability over a wide temperature range. Each fiber squeezer is controlled by a 0-150V analog control voltage.
PCD-M02 with driver board
The PCD-M02 integrates an MPC polarization controller with a miniature piezo driver card that allows the control voltage of each fiber squeezer to be set either by a 0-5V analog control voltage or by a 12-bit TTL digital signal. The board is powered by standard ±12VDC lab power supplies. 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.
The modules are suited to OEM integration wherever a fiber-coupled polarization controller is needed, including test equipment, fiber sensors, fiber lasers and optical network modules.
