Abstract(in English) In the wavelength-division multiplexing (WDM) systems of the future, an architecture that uses the optical add-drop multiplexer (OADM) for signal I/O with respect to the transmission path has been proposed. It is known that changes in the gain of the erbium-doped fiber amplifier (EDFA) that accompany fluctuation in the signal light input to the OADM and changes in Raman gain generated in the transmission path occur in the sub-millisecond order. It is also known that this gain change is gain tilt occurring in the wavelength direction, constituting a factor in the degradation of transmission characteristics. We have developed a fast gain tilt compensator that is capable of operation in the microsecond order and uses lithium niobate (LN) polarization transformer to compensate for the gain tilt due to these gain changes.
