TL;DR: In this paper, the authors presented the first full-system 40 Gb/s TWDM-PON prototype, which is capable of supporting 20 km distance with a 1:512 split ratio.
Abstract: The next-generation passive optical network stage 2 (NG-PON2) effort was initiated by the full service access network (FSAN) in 2011 to investigate on upcoming technologies enabling a bandwidth increase beyond 10 Gb/s in the optical access network. The FSAN meeting in April 2012 selected the time- and wavelength-division multiplexed passive optical network (TWDM-PON) as a primary solution to NG-PON2. In this paper, we summarize the TWDM-PON research in FSAN by reviewing the basics of TWDM-PON and presenting the world's first full-system 40 Gb/s TWDM-PON prototype. After introducing the TWDM-PON architecture, we explore TWDM-PON wavelength plan options to meet the NG-PON2 requirements. TWDM-PON key technologies and their respective level of development are further discussed to investigate its feasibility and availability. The first full-system 40 Gb/s TWDM-PON prototype is demonstrated to provide 40 Gb/s downstream and 10 Gb/s upstream bandwidth. This full prototype system offers 38 dB power budget and supports 20 km distance with a 1:512 split ratio. It coexists with commercially deployed Gigabit PON (G-PON) and 10 Gigabit PON (XG-PON) systems. The operator-vendor joint test results testify that TWDM-PON is achievable by the reuse and integration of commercial devices and components.

TL;DR: Digital signal processing technologies to further enhance NG-PON2 systems by realizing flexible and cost-effective optical access network deployments are reviewed.
Abstract: Motivated by recent progress in next-generation PON2, or NG-PON2, standardization, this article reviews digital signal processing technologies to further enhance NG-PON2 systems by realizing flexible and cost-effective optical access network deployments. First, flexible speed upgrades by DSP-enabled advanced modulation and multiplexing approaches are described, followed by a consideration of cost-performance trade-offs. Next, reach extension using DSP-based digital coherent reception and impairment compensation is overviewed. Finally, as a future goal, access network virtualization with reconfigurable optical line terminals and optical network units is discussed.

TL;DR: In this article, a 40-Gb/s (4 × 10 Gb/s) downstream and 10-battery/s upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation is proposed and demonstrated.
Abstract: We propose and demonstrate a 40-Gb/s (4 × 10 Gb/s) downstream and 10-Gb/s (4 × 2.5 Gb/s) upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation. Here, a downstream differential-phase-shift-keying (DPSK) signal and an upstream remodulated carrier-suppressed single-sideband non-return-to-zero (CS-SSB-NRZ) signal are used, which are wavelength shifted to circumvent Rayleigh backscattering (RB). A silicon-based optical microring resonator (MRR) filter is preinstalled at the optical networking unit (ONU) to select the desired downstream wavelength and simultaneously demodulate the downstream DPSK signal, which is then detected by a monolithic-integrated germanium-on-silicon (Ge-Si) photodiode (PD). Using silicon-based devices could be cost effective for the cost-sensitive ONU. The future monolithic integration of a silicon filter, a silicon detector, and a silicon modulator in the ONU is also discussed. The characteristics of the preinstalled silicon-based MRR and the Ge-Si PD are discussed. Error-free transmission (bit-error rate (BER) <;10-9 ) is achieved in both downstream and remodulated upstream signals after propagating through 20 km of standard single-mode fiber (SMF).

TL;DR: The attention will be focused on the time wavelength division multiplexed PON (TWDM-PON), which is believed to be a promising candidate for the early stage deployment of NG-Pon2.
Abstract: Passive optical network (PON) is widely considered as a promising technology for the fiber-to-the-home (FTTH). In this talk, we will review some of the early works on the second-stage next-generation passive-optical-network (NG-PON2). Then, we will focus our attention on the time wavelength division multiplexed PON (TWDM-PON), which is believed to be a promising candidate for the early stage deployment of NG-PON2.

TL;DR: Silicon-based optical components are now mature technologies; and they can be used in the time-and-wavelength-division-multiplexed passive-optical-network (TWDM-PON) optical networking unit (ONU) to increase the level of integration for cost reduction.

We will also discuss the further migration form the NG-PON2 to the future pure WDM-PON.
