Abstract
Optical component adapted to monitor a multiwavelength link for use as an add-drop multiplexer in optical networks. The optical component includes an input fiber (68) for transmitting signals of different wavelengths, a diffraction grating (70) for dispersing these signals on several orders of diffraction, fibers (72, 74, 76 and 78) for recovering the dispersed signals corresponding to a given order of diffraction, and fibers (79, 80, 82, and 84) for recovering the same signals but corresponding to another order of diffraction so as to monitor the state of these signals.
