Datasheet

Overview

The Luna PSGA-101A is a polarization measurement system that measures all polarization-related properties of light, including state of polarization (SOP), degree of polarization (DOP), differential group delay (DGD), second-order PMD (SOPMD), polarization dependent loss (PDL) and polarization extinction ratio (PER). The manufacturer has discontinued it. Luna lists the Optical Vector Analyzer (OVA 5100) as its replacement.

The system has three main parts: a tunable laser, a polarization state generator (PSG) that produces the six basis polarization states commonly used for measurement, and a polarization state analyzer (PSA) that performs the polarization measurements. The PSG and PSA use Luna's patented magneto-optic polarization generation and analysis technology to measure PDL and polarization mode dispersion (PMD) versus wavelength.

The PSGA-101A can also monitor SOP and DOP, measure PER, measure the Mueller matrix of devices or components, and measure birefringence in spun fiber.

The three modules can be used on their own or together, depending on the measurement. With the internal C-band tunable laser, the system measures PMD up to 10 ps. Larger PMD values can be measured by using external lasers.
