“…In order to validate the simulation model of the proposed network, a comparison between our numerical results and experimental results obtained by Iannone et al [16] has been performed, even if the network here proposed and the one proposed by Iannone et al are different in terms of components and modulation techniques employed: in particular the reference network uses a SOA/Raman hybrid amplifier. Moreover fiber properties and operative wavelengths are different.…”

“…As proposed by Iannone et al [16], this configuration allows to manage the upstream/downstream traffic on ODN without the necessity to introduce a further 1.3 − 1.5 μm multiplexer. The wavelength plan has been established to ensure equal channel spacing among operative wavelengths, saving the coexistence with legacy PON according to their respective ITU-T standards.…”

Abstract-Dense wavelength-division multiplexing passive optical networks (DWDM-PONs) and ultra-dense wavelengthdivision multiplexing passive optical networks (UDWDM-PONs) are strong candidates to future next-generation passive optical network stage 3 (NGPON3) access networks in order to satisfy increasing bandwidth demand, but their deployment is still a great challenge for telecommunication operators. PON (WDM-PON). In order to fulfill this aim, with reference to downstream traffic enhancement, two main novelties are presented: (a) the use of a multi-pump Raman amplifier (MRA) to satisfy the future necessity of large gain bandwidth; (b) the introduction of advanced modulation techniques to increase spectral efficiency and the future number of user channels (a less than -wide channel bandwidth providing / bitrate has been demonstrated). A coherent system has been also proposed and its main impairments have been evaluated. The MRA has been accurately optimized to minimize power consumption without compromising performances. In the upstream direction, a semiconductor optical amplifier (SOA) has been considered. The performances of the proposed TWDM-PON have been predicted through numerical simulations based on a system-level commercial CAD software. Time and wavelength division multiplexed PON (TWDM-PON) has already been chosen by ITU-T as one of the best architectures in brownfield contexts to allow the reuse of the optical distribution network (ODN). Our proposal exploits the advantages of TWDM in order to reach a balance between coexistence with legacy systems and gradual and cost-effective migration towards pure wavelength division multiplexed Index Terms -optical access networks, FTTH, NGPON3, TWDM-PON, Raman amplifier, SOA.

“…One example of a hybrid approach to long-reach PON is based on a combination of coarse WDM and TDM: CWDM allows several TDM PONs to share a common fiber infrastructure 31 . This aggregated spectrum can then be more economically amplified with a common broadband optical amplifier 32 .…”

“…Another next generation upgrade path is to include the wavelength dimension using WDM-PON, e.g., by adding three downstream broadcast coarse WDM (CWDM) channels [11], or by multiplexing four com plete TDM PONs on four downstream and four upstream CWDM channels [5,12].…”
