چکیده
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 respectively, with intensity modulation. The evaluation of system performance is analyzed in terms of bit error rate (BER) verses received power. TWDM-PON achieved successfully an aggregated data rate of 160 Gb/s along 40 km bidirectional fiber at 1: 128 splitting without amplification and dispersion compensation.

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...
متن کاملEnergy efficiency analysis of high speed triple-play services in next-generation PON deployments
In this paper, the energy consumption of high speed access services up to 1 Gb/s per customer is estimated for different passive optical network (PON) technologies. While other studies on PON power consumption typically assume a fixed split ratio, we also consider a greenfield approach, where the split ratio can be optimized for each technology, taking full advantage of its capacity and reach. ...

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...
