ABSTRACT:
In optical transmission systems with fiber-optic amplifiers, an interruption of the fiber-optic link, e.g., due to fiber breakage, may cause a giant pulse to develop. To prevent the giant pulse from propagating in the fiber-optic link, an optical filter (7) which blocks the wavelength region of the pulse is placed in the fiber-optic link. The wavelength of the optical signal must be chosen to lie outside the wavelength region of the maximum gain of the fiber-optic amplifier.
