- Page 4 Section 2. Overview: General Photonics’ in-line polarimeter (PolaDetect) is specially designed for high-speed, low cost polarization monitoring without interrupting data traffic. It outputs four voltage signals for calculating both the degree of polarization (DOP) and the state of polarization (SOP) of the light passing through the device. The measurement applies to the state of the light at the input end of the polarimeter.

General Photonics will only provide the calibration for the POD-xx-xx-02 with an integrated preamplification circuit designed and fabricated by General Photonics.

In the setup, an optional reference polarization analysis instrument can be used to verify the accuracy of the PolaDetect. An analog-to-digital converter card (A/D card) is used to convert the...
- Page 8 In general, the calibration matrix is wavelength dependent. Each matrix is sufficiently accurate for wavelengths within +/- 5 nm of the specified wavelength. General Photonics provides 5 matrices, at 1520 nm, 1530 nm, 1540 nm, 1550 nm, and 1560 nm,...
