Title:
DEVICE FOR MEASURING OPTICAL PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2015/076097
Kind Code:
A1
Abstract:
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 (NAβ) that yields an insertion loss (Lβ) corresponding to the insertion loss (Lα) due to steady-state excitation in the optical fiber (7).
