LUNA PCD-M02/MPC Dynamic Polarization Controller
The LUNA MPC series are electrically controlled, all-fibre polarization controllers based on fibre squeezing technology. They are also available with a driver board as the PCD-M02.
- Low insertion and activation loss
- Fast response
- Compact
- Driver board available
The LUNA MPC series are fibre squeezer based polarization controllers packaged in a low profile 0.63 inch high enclosure. They are available with 3 or 4 fibre squeezers. Either version can generate any polarization state on the Poincaré sphere, but the 4X version provides an extra degree of freedom for reset-free operation and polarization scrambling. The all fibre design is inherently low loss, has minimal activation loss, and operates over a wide wavelength range. The athermal package design provides temperature stability over a wide temperature range. Each fibre squeezer is controlled by a 0-150V analog control voltage.
The PCD-M02 integrates an MPC polarization controller with a driver board that allows the control voltage to each fibre squeezer to be specified either by a 0-5V analog control voltage or by a 12-bit TTL signal. The board is powered by standard ±12VDC lab power supplies.
The MPC/PCD-M02 polarization controllers are small modules suitable for OEM integration wherever a fibre coupled polarization controller is needed.
