We demonstrate the first software-defined OpenFlow1.0-based flex-grid -flow architecture enabling 150Mb/s per-cell OFDMA MBH overlays onto bidirectional 10Gb/s PON, without any ONU-side optica...
We demonstrate for the first time enhanced software defined networking (eSDN) over elastic grid (eGrid) optical networks for data center service migration, the performance of which are first verified ...
We report a network design algorithm to effectively reduce the cost and power consumption of translucent networks by using all-optical 2R regenerators. Simulation results show that the number of O/E/O...
A novel energy-efficient dynamic provisioning scheme is proposed by using an intelligent load control mechanism and an auxiliary graph model. Significant reduction in total energy consumption is achie...
Bi-directional CWDM radio-over-fiber transmission of triple-format full-standard OFDM signals in coexistence (UWB, WiMAX and LTE) (1.178 Gbit/s full-duplex) is demonstrated over 50.6 km SSMF in passiv...
This work examines protection of multicast sessions in optical networks utilizing a novel segment-based algorithm called Level Protection. Our proposed scheme exhibits improved performance compared to...
We compare the cost-efficiency of optical networks based on mixed datarates (10, 40,100Gb/s) and elastic technologies. We show elastic network bring up to 37% lower cost, in particular for high loads ...
A novel orthogonal wavelength-division-multiplexed passive optical network with 25-GHz channel spacing has been proposed and experimentally demonstrated for the first time.Error-free transmission over...
Integrated components for optical networks-on-chip,including III-V microdisk lasers, photodetectors, and wavelength selective circuits, are all demonstrated using a complementary metal-oxide-semicondu...
We experimentally and numerically determined the nonlinear transmission impairments for a hybrid PDM-QPSK/OOK network. Results are quantified via a nonlinear phase metric and can be used as design rul...
This paper presents the implementation of an effective PCE-based management and control platform for heterogeneous optical networks. Experimental results show that it works well on network with commer...
This paper describes promising technologies for access networks from an operator’s viewpoint, especially as regards optical cables and transmission through passive optical networks,with a view to the ...
Brillouin scattering is identified as a severe limitation in narrow line-width,bi-directional reflective systems. A spectrum management mitigation technique for triple-format OFDM signals is demonstra...
We propose a wavelength reusable WDM-PON scheme using protective interconnection fibers to achieve whole optical distribution network protection. 10Gb/s bidirectional transmission is experimentally de...
A multi-layer grooming and routing method, which considers the optical layer constraints, is proposed. This method, based on a new modeling, allows significant resource saving with respect to a layer ...
