High speed converters and DSP for 100G and beyond

Abstract Novel new architectures for ultra-fast CMOS data converters in conjunction with complex DSPs are the key enabling components for optical transport systems at 100 Gbps and beyond. This paper reviews the fundamental CMOS technologies that have enabled real-world deployments of true single-wavelength 100 Gbps optical transport systems along with an analysis of the future possibilities for transport rates beyond 100 Gbps that will leverage continued advances in CMOS converter and DSP designs.
