OPTISCHES ÜBERTAGUNGSSYSTEM MIT VERMINDERUNG DER RAMANEFFEKTSERSCHÖPFUNG

摘要

A Transmission system is proposed using a wavelength division multiplex scheme with transmitters (2), transmission line (4) and receivers (7) with means (3, 6) to multiplex and demultiplex optical signals of different wavelengths with at least one mean (8, 10) in the transmission system (1) to take countermeasures to overcome the depletion due to Raman-shift in the power of the wavelength grid spectrum. Also a method for decreasing effect of power depletion is proposed.
