We analyze the energy consumption of current in-building networks and show that new network designs employing fiber-wireless technologies could lead to significant energy savings in future high-speed networks.
Quasi-Passive and Reconfigurable (QPAR) optical nodes are implemented using two different discrete optical latching switches based on Micro-Opto-Mechanical and Magneto-Optic principles. A clear trade-off between speed and power consumption is noticed for those QPAR realizations.
This article provides an overview of current efforts in reducing energy consumption in passive optical access networks. Both ITU-T and IEEE standardized PONs are considered. The current solutions proposed by standardization authorities, industry, and academia are classified based on the layer they address in the standardized architectures: physical layer, data link layer, and hybrid. Then, the article...
A novel optical phase-modulated wireless-over-fiber backhaul architecture for next generation cellular network is presented and experimentally demonstrated for high capacity wireless multicarrier uplink transmission on a single wavelength.
Optical and wireless technologies have complementary characteristics in capacity and mobility. This talk describes our research toward the convergence of both optical and wireless technologies to address the needs of future access networks.
Next-generation optical access networks will deliver substantial benefits to consumers including a dedicated high-QoS access to bit rates of hundreds of Megabits per second. They must also deliver significant benefits to network owners/operators to justify the needed infrastructure investment expected to reach billions of Euros. Benefits to network owners/operators are expected to include reduced...
The new Energy Efficient Ethernet standard will significantly improve the energy efficiency of 10 Gbps copper transceivers. This paper compares the energy efficiency of 10 Gbps Ethernet copper transceivers that implement the new standard with fiber transceivers.
A new scheme for adaptive optical power equalization in passive optical networks is proposed based on dynamic gain control of semiconductor optical amplifiers. Because of this new scheme, continuous-mode receiver front-end can be used for upstream burst-mode transmission. Experimental testbed is demonstrated with -31dBm receiver sensitivity and >34dB dynamic range using continuous-mode receiver...
