Abstract :
A novel technique is proposed to reduce fiber fourwave mixing (FWM) in multichannel transmissions. Transmitters are constructed such that the light for one channel is composed of two incoherent orthogonal polarized lights. Theoretical treatment indicates that the FWM light power can be reduced by 3/8 and that the noise power due to the FWM light can be reduced by 3/16 by using the new technique. Results of preliminary experiments confirm the efficacy of the suppression mechanism
