标准摘要
[中文适用范围]： 本部分规定了测量耦合功率比(CPR)系数的方法。按GB／T 18311．4—2003测量多模光纤衰减和 插入损耗时，CPR用于表征光源特性和使注入条件标准化。 可以在850 nm和1 300 am波长下测量CPR系数。 [外文原描述]： Provides the method to measure the coupled power ratio (CPR) coefficient. The CPR coefficient may be measured at both 850 nm and 1 300 nm wavelengths. CPR measurements are used to characterise optical sources and to standardize the launch conditions for measurements of attenuation on multimode fibres and inseration loss according to IEC 61300-3-4.
