| 摘要 |
This fiber coupling module has an optical fiber connector (5) to which an optical fiber cable (6) can be detachably connected and is connected to the optical fiber cable via the optical fiber connector, said optical fiber cable (6) having a low reflective film (50) applied to the end face thereof. The low reflective film (50) has a reflectance set lower than a given value for light in a first wavelength range and set equal to or higher than a given value for light in a second wavelength range excluding the light in the first wavelength range. A main light source (2) outputs the light in the first wavelength range to the optical fiber cable. An auxiliary light source (7) outputs the light in the second wavelength range to the optical fiber cable. A detector (10) detects the state of connection between the optical fiber cable and the optical fiber connector on the basis of the light in the second wavelength range reflected thereto from the end face of the optical fiber cable. |
