Abstract

The invention concerns a system for obtaining characteristic spectral information of light emitted from an optical fibre (10). The system comprises an optical spectrograph (12, 13, 14, 15) and a detector (16, 17). The spectrograph comprises a diffraction grating (13) that diffracts light in the wavelength band 800 - 1,700 nm, or parts thereof, into spectral orders in one plane of spreading, and a wavelength dispersing means (14) that spreads the wavelength components in a plane of spreading that is perpendicular to the first plane of spreading. A digital camera (17) with a detector surface (16) records the images of the light, and a computer (19) converts the signals into a spectrum and calculates magnitudes that are characteristic of the optical fibre (10), for a light source (21) that illuminates the fibre and/or for other electro-optical components that are used in optical telecommunication.
