Signaling at 160 Gb/s Data Rate and Beyond

Abstract

Historically the developemnt of new optical transmission systems has been towards increasing the data rate per channel since it is expected that moving signal processing to higher speed will lower the hardware cost per transmitted bit, shrink the required equipment footprint, and reduce the power consumption for a given system capacity.  The current generation of high-speed WDM transmission systsems is running at 10G and 40G data rates and can provide sufficient capacity for several practical applications. But it is expected that the historical trend in SONET and SDH optical communication techniques continues, which means that the line rate quadruples from one network generation to the next one. Thus 160Gb/s will be the next higher important line rate for optical networks. We will review recent trends in the field of ultra high-speed signaling and discuss current approaches to generate the corresponding modulation formats.
