Dynamic Wavelength and Bandwidth Allocation with QoS for TWDM PON
We propose a dynamic wavelength and bandwidth allocation algorithm with QoS (quality-ofservice) for a TWDM PON (time and wavelength division multiplexing passive optical network) system of NG-PON2 (next generation PON stage 2). Unlike other existing methods, the proposed method supports multiple service classes and is compliant to the NG-PON2 recommendation. To increase the wavelength allocatio...
متن کاملEnergy Efficient Dynamic Wavelength and Bandwidth Allocation for TWDM PON
This paper proposes a new dynamic bandwidth and bandwidth allocation (DWBA) algorithm for energy saving in time and wavelength division multiplexing passive optical networks (TWDM PONs). Decreasing the number of active upstream wavelengths, the proposed algorithm not only saves power but also provides good efficiency for TWDM PON systems. Using simulations, we evaluate performance of the propos...
متن کاملA symmetric 160 Gb/s Broadband TWDM-PON
This paper studies and designs a symmetric 160 Gb/s and improves the capacity of time and wavelength-division multiplexed passive optical network (TWDM-PON) for nextgeneration passive optical network stage 2 (NG-PON2). Distributed feedback (DFB) laser diode and tunable modulated grating Y-branch (MG-Y) laser with tuning range about 14.4 are used for downstream and upstream direction respectivel...
متن کاملBroadcasting and Multicasting in All Optical Packets Routing TWDM PON
Requirements for future bandwidth demand from access network keep changing, in order to support more streaming video on multicasting and broadcasting packet, a novel architecture of dynamic Multiwavelength Time Wavelength Division Multiplexing Passive Optical Network (TWDM PON) system using multicasting Cross Gain Multiplexing (XGM) and all optical packet routing (AOPR) module in optical line t...
متن کاملCompatibility between coherent reflective burst-mode PON and TWDM-PON physical layers.
We discuss the compatibility between reflective PON architectures and the recently defined ITU-T G.989.1 TWDM-PON. Focusing on the upstream, we experimentally demonstrate that, by using burst-mode coherent detection at OLT, reflective PON can achieve the specification target set for TWDM-PON, without requiring precise wavelength accuracy at ONU. Compared to the companion ECOC 2013 paper, we inv...
