Application Summary AI generated
This standard specifies the test and measurement procedures for determining the extinction ratio of connectors terminated with polarization-maintaining (PM) fiber pigtails. It is applied in the telecommunications and fiber optic industries to ensure the polarization-maintaining performance of these connectors, which is critical for applications such as coherent optical communications, fiber optic sensors, and high-precision interferometry. The standard provides a consistent method for evaluating how well the connector preserves the polarization state of transmitted light.
