Demonstration of Converged Bidirectional OFDM-m-QAM RoF and WDM-OFDM-PON Access Networks
Networks Optical communications
2015/5/26
We demonstrate a novel lightwave centralized hybrid bidirectional WDM-OFDM-PON and OFDM-m-QAM RoF network. The 11.29-Gb/s OFDM-16QAM wired DL, 5.65-Gb/s OFDM-QPSK wired UL and WiMAX downstream/upstrea...
Architectural Optimization of Coherent Ultra-Dense WDM based Optical Access Networks
All-optical networks Coherent communications Networks
2015/5/22
Different architectures for achieving ultra-high aggregate data rate PON are compared and optimized. An ultra-dense scheme is used to set the limits for the technology and a strategy for minimizing in...
Coherent technology is the only viable solution to fulfill requirements regarding data rate, reach and splitting factor for optical access. Cost of optics is compensated by savings in system design to...

2015/5/21
The components for next-generation access networks enable broader-band delivery by higher-speed operation, more wavelengths, and more integration. Economic considerations determine more and less likel...
OLARP:Open Lambda Assignment and Routing Problem – Bandwidth Multiplier for Metro and Access Networks
OLARP Open Lambda Assignment Routing Problem – Bandwidth Multiplie Access Networks
2015/5/21
We consider, for the first time, the problem of flexible/open wavelength assignment and propose an optimal as well as heuristic solution. Simulation results validate our solution to within 15% of the ...
FSK+ASK/ASK Operation for Optical 20/10 Gbps Access Networks with Simple Reflective User Terminals
FSK+ASK/ASK Operation Access Network User Terminals Simple Reflective
2015/5/18
Doubling of the downstream rate by reusing the reflective upstream modulator is demonstrated. With just two photo-detectors, a RSOA and a power splitter at the ONU, a 20/10 Gbps mode can be provided p...
Using Wavelength Splitting at the Remote Node to Mitigate Rayleigh Backscattering for Optical Wired and Wireless Access Networks
Fiber optics communications Optical communications
2015/6/10
We demonstrate an optical wired and wireless access network using wavelength-splitting (WS) at remote-node. A pair of CW carriers is generated from each laser source for wired and wireless application...
Power efficiency of optical versus electronic access networks
Power efficiency optical versus electronic access networks
2015/7/30
Based on a model of a typical operator network we have compared the power consumption of different broadband access technologies and architectures especially DSL, FTTN + VDSL and FTTH. Even though pow...
