Identification of cost and energy efficient multiplexing techniques for LR-PON for different network scenario

With the increasing bandwidth demand, passive optical network is considered as the most suitable and promising candidate to support the future access networks. In this paper, we analyze and identify the most appropriate remote node combination for different network scenarios for different fiber reach and subscribers. We cascade the power splitter and arrayed waveguide grating (AWG) at remote to give hybrid TDM-WDM PON. Hybrid multiplexing provides efficient use of optical line terminal (OLT) resources and reduces the required wavelengths and transceivers. Reduction in wavelength and transceivers results in designing energy and cost effective access network. This study will help the network operators to choose the most appropriate remote node architecture to give economic and environmental friendly services for different network scenario.
