We review currently discussed solutions for 80 km DWDM transmission targeting inter data-center connections at 100G and 400G line rates. PDM-64QAM, PAM4 and DMT are investigated, while the focus lies on directly detected solutions.
The results were obtained in the framework of the SASER-ADVAntage-NET project, partly funded by the German ministry of education and research (BMBF) under contract 16BP12400
