Due to the emerging bandwidth-hungry applications (e.g., high-quality video content), the traffic load may significantly vary in time across the access network. Therefore, the network operator should be capable of distributing the available bandwidth in a flexible manner in order to provide the end-user with an uninterrupted service. In this letter, we present the experimental results carried out on the testbed of a hybrid wavelength-division-multiplexing/time-division-multiplexing access network based on cost-efficient elements like an integrated optical add-drop multiplexer and a reflective electroabsorption modulator combined with a semiconductor optical amplifier which provides bandwidth on-demand. We successfully transmit simultaneous upstream and downstream traffic at 10 Gb/s/lambda (nonreturn-to-zero) over 27-km standard single-mode fiber in various configurations of four wavelengths.

- "That is, the contribution of bandwidth per extra-wavelength channel is 19 Mb/s at each ONU. By doing so, upgrading the GPON capacity to support high bandwidth requirements becomes cost-effective, since no modification at the splitter is performed as seen in (Koonen, 2006), (Urban, 2009), (Koonen, 2011), which undoubtedly increases the overall network costs, but the added bandwidth is shared between the whole system due to the passive distribution behavior of a PON network while the dynamic bandwidth allocation relies on the use of tunable filters at each ONU to select the wavelength(s) channel(s) according to the bandwidth demand of the ONU.

ABSTRACT: Vivid facial expressions contribute greatly to the visual realism of 3D face models. However, it is often tedious and expensive to model facial details which are authentic and real-time. In this paper, a simple and functional approach for modeling dynamic wrinkles of face is introduced. Started with structured facial mesh, we divide face region into some wrinkle subregions, and create some wrinkle lines with our algorithm in these subregions. Then, some key nodes are labeled on the facial mesh, these key nodes affect wrinkle lines if wrinkle lines locate the subregions that abut on the key nodes. With our algorithm, motion of wrinkle lines is produced by movement of key nodes. Consequently, wrinkle lines drive facial mesh to model expressive wrinkles. In this way, we create dynamic and functional expressive wrinkles of individuals available to date and demonstrate their use in facial animation.

ABSTRACT: In this paper we give an overview of different approaches to reduce the influence of the interferometric crosstalk in a Passive Optical Network employing Wavelength Division Multiplexing (WDM-PON) and a Reflective Semiconductor Optical Amplifier-based (RSOA) transceiver in the Optical Network Unit (ONU). Key advantages and disadvantages of each method are given.
