GB/T 18311.31-2007 Fibre optic interconnecting devices and passive components Basic test and measurement procedures Part 3-31 : Examinations and measurements Coupled power ratio measurement for fibre optic sources (English Version)
This section specifies the method for measuring the coupling power ratio (CPR) coefficient. When measuring multimode fiber attenuation and insertion loss according to GB/T l8311.4-2003, CPR is used to characterize light source characteristics and standardize injection conditions. CPR coefficients can be measured at 850 nm and 1300 nm wavelengths.
