DWDM technology can be applied to different areas in the telecommu-nication networks, which includes the backbone networks, the residential access networks, and also the Local Area Networks (LANs). Among these three areas, developments in the DWDM-based backbone network are leading the way, ...
This paper presents an overview about WDM technology and recent developments in this field and how the overall capacity of the communication network can be incremented using this technology. 展开 关键词: bandwidth multiplexing optical network unit OCDM passive optical network ...
In a circuit-multiplexed network, a flow in the network is identified at setup time by the sequence of channels it is assigned to. With packet multiplexing, however, there is additionaloverhead, because each packet must carry aheader(and perhaps atrailer) that identifies the flow to which the...
In both cases, the entire bandwidth assignment's planning need not be carried out during the initial deployment of a network. However, with reconfigurable optical networks being a relatively a new technology, the community is still discussing their conceptual fundamentals, benefits, and limitations. ...

Overview of WDM-PON Network & 5G As it’s known to all, WDM-PON (Wavelength Division Multiplexing-Passive Optical Network) combines WDM technology with PON topology structure that allows operators to deliver high bandwidth to multiple endpoints over long distances. It includes some technologies, inc...

This chapter provides an overview of the technology challenges for the implementation of future high-capacity systems incorporating channels at bit rates of 100 Gb/s and higher. It explains the improvements needed in optical signal-to-noise ratio (OSNR) enhancement, and robustness against linear and...
In this proposed CAMR scheme, nodes decide whether they belong to the sparse part of the network or the dense part, by finding the mean of the total neighbors they have. If they have, on an average, more than a threshold number of neighbors, then they belong to the denser region of ...
