considered to be a primary solution for next-generation passive optical network stage 2 (NG-
PON2). Due to the feature of multi-wavelength transmission of TWDM-PON, some of the
transmitters/receivers at the optical line terminal (OLT) could be shut down to reduce the
energy consumption. Therefore, a novel scheme called traffic-aware energy saving scheme
with modularization supporting is proposed. Through establishing the modular energy …
