Abstract
We present in this Chapter an overviewof optical fronthauling technologies
for fixed-mobile convergence in next generation 5G access networks. The Chapter
first introduces the general concept of Cloud Radio Access Network, or C-RAN, then
it presents the most common proposals for fronthauling, based on Digitized Radioover-
Fiber, or D-RoF, according to the CPRI or OBSAI standards. The Chapter then
prosecutes by presenting the very recent evolutions of D-RoF toward the "functional
split" paradigm, as already available in the latest releases of the CPRI specifications.
Finally, some recent research trends towards Analog RoF are presented. The Chapter
is intentionally written in a tutorial way, to be used by newcomers in this field. It
anyway also reports a vast set of bibliographic references to guide the interested
reader toward more detailed technical presentations
