Abstract—As for the problems of complexity and long cycle
in the DWDM design, part of problems needed to be
considered in DWDM system design were analyzed. An
optimized point-to-point DWDM transmission system was
designed. Optical fiber commu

The all-optical wavelength conversion gives flexibilities to the optical fiber communication
networks, especially to the wavelength-division-multiplexed (WDM)-based ones, because it allows
them to reuse wavelengths and to avoid wavelength channel
