Abstract

The ongoing progress in 40-Gb/s system technologies has made it possible to achieve transmission capacity of several-terabits with only a moderate number of channels in the already-practical optical C and L bands for future ultra high capacity WDM networks. To increase capacity to the 10 Tb/s level, however, it is essential to expand optical bandwidths and to use them as efficiently as possible. This paper discusses these two topics and also the effect of inter-band Raman scattering on transmission we assessed in a 10-Tb/s experiment.¹
