The PPC programmable controller is an instrument that integrates polarization control function and polarization disturbance function in Dimension Technology, and is an important testing instrument for optical passive testing systems.
Polarization disturbance function: Based on high-speed optoelectronic materials as phase controllers, three boards are guided at different angles to convert any polarization input state into a random polarization state, covering the Poincare sphere at high speed, and finally outputting a stable circularly polarized light. It has excellent performance with low insertion loss and high disturbance frequency. Its deviation frequency can reach up to 5MHz.
Polarization control function: By controlling the signal, different polarization states of light can be output, and polarization state scanning can be controlled through software. Combined with the high-speed optical power meter synchronous sampling of Dimension Technology, it can perform high-speed automated testing on the polarization correlation of optical devices, with a maximum scanning speed supporting 10kHz.

This device integrates polarization control function and polarization disturbance function. The two modes can be switched through the panel buttons, and the high-speed scrambling function can reach 5MHz.

Polarization control range: 0-4 π per channel

Unlike ordinary polarization controllers that can only control 0-2 π, Dimension Technology's polarization control range can reach 0-4 π per channel, achieving ultra-high range polarization control, achieving more polarization state display, and improving testing accuracy.

Due to the advantages of programmable control, this device can directly set and adjust the relevant polarization state change frequency to be consistent with the frequency read by the power meter, and cooperate with the high-speed optical power meter of Dimension Technology to achieve ultra-high speed automated polarization state testing at 10kHz& Nbsp;
