    • This invention provides a device for measuring an optical-fiber component, said device being capable of obtaining measurement results for insertion loss with a high degree of reproducibility and without using a large amount of optical fiber. Said device contains a light source (3) that emits measuring light (DL), an optical fiber (7), and a launch connector (9). The measuring light (DL) enters the optical fiber (7) from one end thereof, and the launch connector (9) is connected to the other end of the optical fiber (7). The measuring light (DL) that enters the optical fiber (7) has a numerical aperture (NAp) that yields an insertion loss (L ² ) corresponding to the insertion loss (L ± ) due to steady-state excitation in the optical fiber (7).
    • 本发明提供了一种用于测量光纤部件的装置,所述装置能够以高重复性获得插入损耗的测量结果,而不需要使用大量的光纤。 所述装置包含发射测量光(DL)的光源(3),光纤(7)和发射连接器(9)。 测量光(DL)从其一端进入光纤(7),发射连接器(9)连接到光纤(7)的另一端。 进入光纤(7)的测量光(DL)具有数值孔径(NAp),该数值孔径产生对应于由光纤中的稳态激励引起的插入损耗(L±)的插入损耗(L 2) 7)。
