DEVELOPMENT OF THE STAND FOR RESEARCHES SPECTRAL CHARACTERISTICS OF THE OPTICAL FIBRE

The main high-speed fiber-optical systems of transfer with spectral condensation of channels of optical amplifiers of the running wave, leading distortion of spectral characteristics of a group optical signal are considered. The given distortions after repeated amplification lead to ful l or part ial loss of an alarm stream. Equalization of the through passage characteristic of each amplifier of a running wave allows to reduce these distortions. The decision of this problem probably use of one or several devices, in the form of acoustic optical filter on SAW, for equalization a spectrum in path FOST.
