Adaptive bandwidth aggregation mechanisms using a shared wavelength for energy-efficient WDM/TDM-PON

This paper proposes a WDM/TDM-PON architecture using a shared wavelength and a technique to aggregate narrowband traffic to reduce power consumption of the optical line terminal (OLT). The proposed WDM/TDM-PON enables efficient power saving in the presence of narrowband services, for example, those expected in smart communities and sensor networks.
