Wavelength ranges available
(Any custom range available upon request)
Covering the operating wavelength ranges from 1260 to 1610nm, it offers excellent performance, fast sampling rate, high SOP accuracy, and wide dynamic input optical power range. Optionally, it can be used in combination with an internal Optical Filter to measure the SOP as a function of frequency. Intuitive software and touch screen allows an easy manipulation of the device.
Available wavelength ranges:
O Band
1260 – 1360 nm
C+L Band
1525 – 1630 nm

Principle
The incident optical signal is converted into four electrical currents I, via four internal photo-detectors. Each signal corresponding to a different phase (polarization) is analyzed separately.
SOP and DOP measurements
After performing a calibration using a linear polarizer at 0 and 45° for the horizontal calibration or at 90° and 45° for the vertical calibration, we display the state of linear polarization input signal by variating the linear polarizer angle between 0 and 360°.
Polarization extinction ratio measurement
Our Fiber-coupled Polarimeters can be used to measure the polarization extinction ratio of PM fibers. By applying mechanical stress (stretch, heat) on the fiber, the measured points forms a circle on the Poincaré sphere. The PER is then calculated from the radius of the circle.
PM fiber alignment
Our series of Fiber-coupled Polarimeter can be used to align the polarization axis of PM fibers and for fiber splicing in real time. This experiment is performed by rotating and stretching one of the two fibers.
Available as an integrated component
The same performance in an electronic card assembly or component-only, for direct integration into a proprietary design.
