Abstract

Increasing demand for broadband services enhances interest in high-capacity transport networks. A multigigabit cellular photonic transport network architecture has been proposed, and a demonstrator has been realized with commercially available components.¹ In this wavelength-division-multiplexed (WDM) network demonstrator, where channels were equally- spaced, dispersion-shifted fiber (DSF) was used to suppress chromatic-dispersion limitations. However, depending on the zero-dispersion wavelength value, performance degradation due to cross talk resulting from four-wave mixing (FWM) can impose drastic restrictions on launched power.^2,3
