This paper describes how four-wave mixing (FWM) noise within multifiber linear-lightwave WDM ring networks is reduced due to their thin wavelength density. Preliminary numerical analysis for a full-mesh connection pattern shows that a simple wavelength insertion technique can improve FWM noise performance as high as about 10 dB.
