CUBE-PM100

Linear Polarization Maximizer/Generator

CUBE-PM100 is a motorized linear polarization generator that converts input broadband light to highly linearly polarized light (PER > 50dB) 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.

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.

CUBE-PM100 can also be used as a liner polarization generator when the Jones Matrix Eigenanalysis method is used to measure the PMD and PDL of optical devices.

Operation Principle

CUBE-PM100 is a motorized linear polarization generator that consisting of an input connector, a built-in depolarizer, a collimator, a focusing lens, a motorized high ER polarizer, and an output connector. The input light passes through the built-in depolarizer, and is collimated to a parallel beam by a collimator, then passes through a focus lens and high ER polarizer, and finally free-spacely coupled into the output fiber. The polarizer can be rotated to any angle from 0 to 360 degrees by the motor.

Users can remotely control CUBE-PM100 through the full-speed USB 2.0 port on the rear panel. The DB9 socket on rear panel provides a UART interface, through which CUBE-PM100 can directly read PER and angle measurement results from the polarization extinction ratio meter CUBE-ER100, thereby optimizing the angle between the polarization plane and the axis of PM fiber to achieve the maximum PER output.

CUBE-PM100 can also be used as a linear polarization source together with a polarimeter or CUBE-ER100 to measure the PMD and PDL of optical passive components.
