Lab and production measurement technology


The Distributed Polarisation Crosstalk Analyser from General Photonics is a white light interferometer that allows spatially resolved information to be obtained on the mechanical stress of a PM fiber.
The POD-201 is an FPGA powered polarimeter specially designed for high-speed polarization analysis and monitoring. The instrument uses four channels to simultaneously obtain the four Stokes parameters and measure the instantaneous state of polarization (SOP) and degree of polarization (DOP) of an input light beam.

The ERM-202 is a dual channel polarization extinction ratio (PER) meter specifically designed to simultaneously measure the PER and power ratio of a device with two polarization maintaining (PM) outputs, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS), as well as evaluate the performance (output DOP) of depolarizers.

The OCA-1000 is a multi-channel optical component analyzer capable of performing simultaneous insertion loss (IL), polarization dependent loss (PDL), and optical power (P) measurements on multiple optical paths.

The DOP-201 measures and displays the Degree of Polarization (DOP) of a light source in real time with high accuracy and wide dynamic range.

GPCs' 4-axis Polarization Scrambler Module uses a breakthrough all-fiber technology to effectively randomize polarization states. Depolarizing by polarization scrambling has many important applications:
GPCs' high-speed polarization state generator (PSG) module provides the ability to generate 6 states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré Sphere in less than 250 ?s, with an impressive repeatability of less than 0.1 degrees.
This module integrates a General Photonics all-fiber dynamic polarization controller with miniature piezo driver card, so that the SOP of the signal can be directly controlled either by a 0-5V analog control signal or a 12-bit TTL digital control signal. Because there is an on-board HV DC/DC converter, no external high voltage power supply is required.
