Overview
The PCD-M02 combines an MPC series all-fiber dynamic polarization controller with a miniature piezo driver card. The voltage applied to each fiber squeezer can be set either by a 0-5V analog control signal or by a 12-bit TTL digital control signal, so the state of polarization of the optical signal can be controlled directly from analog or digital electronics.
An on-board high-voltage DC/DC converter removes the need for an external high-voltage supply. The card can be configured to accept either a ±12 volt power supply or an external 160-volt power supply, and 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 polarization controller is available with 3 or 4 fiber squeezers.
The all-fiber design provides low insertion loss, low back reflection and low activation loss, in a compact size suited to system integration, OEM modules and handheld devices.
