Automated PER Measurement Duo

This is the CUBE-ER100 and CUBE-PM100 Duo for automated high dynamic PER measurement (>46dB)

CUBE-PM100 converts the polarization of the input broadband light to linear polarization through a higher PER (>50dB) polarizer. It then couples the linearly polarized light into the PM fiber under test. After pressing the AUTO button, the polarizer built into the CUBE-PM100 will rotate until the PER at the PM fiber output reaches its maximum. The entire measurement can be completed within 10 seconds.

In the polarization extinction ratio (PER) measurement of a polarization maintaining (PM) device under test (DUT), large PER measurement uncertainties often arise if the PER of the light source is low or is not well aligned with the PM fiber axis. To minimize such measurement uncertainties, In-line Photonics is proud to introduce the industry’s first automated PER measurement duo, which can automatically eliminate the error sources in the PER measurements. The duo comprises a polarization maximizer cube (CUBE-PM100) and a PER meter cube (CUBE-ER100), which are coordinated to automatically optimize the linear polarization into the PM fiber pigtail of DUT while measuring the PER at high speed. Collectively, they reduce the total PER measurement time (including setup time) to under two minutes while assuring a high measurement accuracy with an uncertainty of less than 0.25 dB, which are more than ten times the improvement for both the measurement time and accuracy over conventional PER measurement systems.

CUBE-PM100 is a motorized linear polarization generator that converts input broadband light to highly linearly polarized light (PER > 46dB) and couples the light into a PM fiber in free space. A motor can finely adjust the angle between the linear polarization and the PM fiber axis to achieve an over 46 dB maximum PER.

The CUBE-E100 is a high-performance PER meter with a PER measurement range of 52 dB, an angular resolution of 0.03 degree, a wide operating wavelength range from 600nm to 1620nm, and a fast measurement speed of up to 50 data points per second.

CUBE-PM100 is designed to replace the inline polarizers and the time-consuming fusion splicing between the inline polarizer and the DUT in conventional PER measurement systems. Instead, the user connects the input and output PM fibers of DUT to CUBE-PM100 output and CUBE-ER100 input through two FC bare-fiber adapters, respectively. Then the CUBE-PM100 will automatically read PER test results from CUBE-ER100 through the UART port and retrieves the maximum PER by optimizing the alignment angle in CUBE-PM100. With the duo, no more worries about the PER measurement uncertainties of PM fibers or devices.
