Examinations and measurements - Coupled power ratio measurement for fibre optic sources Ingestion-build-105964 Visual indicatorWhat is BS EN 61300 3 31 Coupled power ratio (CPR) coefficient about? BS EN 61300 3 31 is an international standard that discusses the test and measurement procedures for fibre optic interconnecting devices and passive components. BS EN 61300 3 31 describes the method to measure the coupled power ratio (CPR) coefficient. CPR measurements are used to characterize optical sources and to standardize the launch conditions for measurements of attenuation
