Towards Multi-Band WDM Systems with Hundreds of Terabit/s Transported on one Single-Mode Fiber

Abstract

Optical networks are facing a tremendous growth of their traffic that can reach up to 40% per year. Multi-band WDM systems have the potential to transmit up to ~200 Tbps over few hundreds of kilometers on one single-mode fiber. We will review the techniques (in particular, optical amplification) that make these systems work.
