Downstream transmission dimensioning in FDMA-PON architectures: Results from the EU project “FABULOUS&#x201D (original) (raw)

Single-Wavelength Downstream FDMA-PON at 32 Gbps and 34 dB ODN Loss

IEEE Photonics Technology Letters, 2015

We propose a PON solution to reach 32 Gbps over a traditional high loss downstream splitter-based optical distribution network (ODN) without using multiple wavelengths at the OLT side nor massive digital signal processing at the ONU side. The achieved 32 Gbps capacity is not too far from the 40 Gbps given by a 4-wavelengths TWDM-PON but completely avoids the handling of multiple wavelengths thanks to a higher electrical spectral efficiency and some system optimization.

Upstream transmission in a reflective FDMA-PON: Results from the EU project FABULOUS

2014 European Conference on Networks and Communications (EuCNC), 2014

In this paper, we present a new FDMA-PON (Frequency Division Multiple Access-Passive Optical Network) architecture proposed by the FP7 EU STREP project titled "FABULOUS". The paper is focused on the upstream transmission, based on an innovative reflective optical network unit (R-ONU). A detailed theoretical analysis is first presented and used to optimize the system parameters, then we show the experimental results, demonstrating a 16 Gbps upstream bit rate per wavelength.

Optimization of Reflective FDMA-PON Architecture to Achieve 32 Gb/s Per Upstream Wavelength Over 31 dB ODN Loss

Journal of Lightwave Technology, 2015

In the framework of the EU-funded research project "FABULOUS" we experimentally demonstrate an innovative FDMA-PON architecture whose upstream transmission is based on a reflective Mach-Zehnder modulator. By a careful optimization of electrical spectrum allocation, semiconductor optical amplifier biasing point and modulation index, we upgrade previous results over similar architectures, significantly increasing the achievable optical distribution network loss. We demonstrate an overall upstream capacity of 32 Gbps per wavelength over 37 km of installed fiber and 31 dB loss.

System aspects of the FDMA PON conceived within the FABULOUS European project

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014

We experimentally demonstrate a FDMA-PON system targeting 20 Gbps per wavelength in the upstream, using a real-time FPGA-based transmitter and low-speed baseband DSP, and 39 Gbps in the downstream using a new resources allocation algorithm with 11.5GHz electrical bandwidth, in the framework of the EU research project FABULOUS.

Future Generation of Passive Optical Networks

In this paper, a WDM-OFDM-PON architecture based on quadrature-amplitude-modulation (QAM) orthogonal frequency-division-multiplexing (OFDM) for downstream and upstream channels is presented. In our simulation, we theoretically demonstrate the architecture based on centralized-light source using direct detection which is a promising solution for ever increasing demand of bandwidth. For downstream channel, 10-Gbps 16-QAM OFDM signal is successfully transmitted over the distance of 50-km single-mode-fiber.

Review and comparative assessment of FDMA-PON vs. TDMA-PON for next-generation optical access networks

Optical Fiber Technology, 2015

We present in this paper a comparative assessment of Time Division Multiple Access Passive Optical Networks (TDMA-PON) and Frequency-Division Multiple Access Passive Optical Networks (FDMA-PON). We try to point out the pros and cons of the two different approaches in the context of very high capacity next-generation PON mainly in terms of physical layer transmission performances, but also introducing some comparison in terms of complexity, cost and power consumption.
