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.
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.

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.

In this paper we present the FDMA-PON (Frequency Division Multiple Access-Passive Optical Network) architecture proposed by the FP7 EU STREP project titled "FABULOUS", focusing on downstream transmission. We experimentally demonstrate that the proposed architecture allows to reach 16 Gbps aggregated capacity per downstream wavelength over an optical distribution network with 30dB loss, still using direct-detection receivers and requiring relatively low speed digital signal processing at the ONU side.
European Conference and Exhibition on Optical Communication, 2012
We demonstrate a greater than 42 dB optical distribution network power budget in the upstream of a 1.25 Gbps self-coherent reflective PON after 100 km of installed fibers, using off-the-shelf optoelectronic components, improving our previous result by 4 dB. We discuss all system optimizations introduced in the setup in order to reach such a result, including 8B/10B high-pass filtering and Faraday rotation at the ONU.
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.
