Technologies and practical aspects of next generation optical networking

We have been witnessing a rapid transition to unified packet-based core/edge network architecture by major telecom carriers all around the globe. Core network architecture becomes a two-layer structure based on data packet transport over DWDM (Dense Wavelength Division Multiplex) bandwidth pipes, which is the most effective way of providing sharing network capacities, enabling efficient protection schemes, and delivering guaranteed end-to-end performance. At the same time, there is a need for the next generation optical access network that will deliver packetized bandwidth to both residential and business end users. In this paper we will review the technologies and practical aspects related to the next generation optical networking.
