New optical access technologies allow network operators to cope with larger client count and longer access distances,

as well as to deliver larger bandwidth. This paper focuses on next generation optical access network architectures using

Wavelength Division Multiplexing (WDM) to interconnect heterogeneous end points. In other words, this work looks

into converged access networks where the end points can be cabinets, Macro Base Stations (MBS) or Small Cells (SC),

which are required at some locations to improve the coverage and the delivered bandwidth
