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, reaching an overall upstream capacity of 32 Gbps per wavelength over 31 dB ODN loss in several previously published experiments targeting 1 Gbps per user and using 16-QAM as a modulation format....
We review alternative solutions for optical fronthauling in next generation fixed-mobile converged architectures that try to solve the problems related to the extremely high bit rates required by current fronthauling implementations based on the so-called digitized Radio over Fiber (as for the CPRI or OBSAI standards). In particular, we present our most recent results on Digital Signal Processing...
We propose a fully bidirectional and symmetrical 10 Gb/s on–off keying Passive Optical Network (PON) solution, using the same wavelength in both upstream and downstream directions. Thanks to the remodulation performed by the optical network unit, it is able to transport 20 Gb/s per wavelength using only one optical source for the full network, regardless of the number of users. The system is based...
In this paper we demonstrate the transmission of LTE channels with the DSP-based channel aggregation, for front-hauling applications, over at least a class N1 PON, ranging from EVM=4% for 24 channels up to EVM=8% for 96 channels.
We demonstrate a single-wavelength fully-bidirectional and symmetrical 10 Gbps OOK transmission using simple direct-detection in downstream, and self-coherent detection in upstream over a standard 31 dB loss splitter-based PON, relying on wavelength remodulation.
In this paper we evaluate the performance of an optical interconnect configuration based on the wavelength remodulation approach, in order to realize a laser-less node that could allow massive integration in silicon-photonics, making reuse of the downstream wavelength for upstream transmission.
In this paper we speculate about the possibility of introducing master-slave configurations instead of pear-to-pear configurations in the optical-interconnect environment, in order to realize laser-less slave nodes that could allow massive integration in silicon-photonics, making reuse of the downstream wavelength for upstream transmission.
In this paper we present innovative master-slave configurations for optical interconnect, proposing solutions with laser-less slave nodes. Purpose of this activity is to project transceivers able to allow massive integration in silicon photonics.
In this paper we present our final results on the real-time implementation on an FPGA platform of the digital signal processing required in the FDMA-PON architecture studied in the EU project "FABULOUS". ". For the first time, we demonstrated simultaneous upstream and downstream real-time transmission capable of carrying Gigabit Ethernet bidirectional traffic to each ONU.
We present a final demonstration of upstream FDMA-PON transmission on the EU project FABULOUS architecture. We show WDM capability over four wavelengths, each carrying 32 Gbps at 31 dB ODN loss, and DSP real time implementation on a commercial FPGA.

We demonstrated PM-64QAM, 20×124.8-Gb/s Nyquist-WDM over 1306 Km of PSCF in an EDFA-only submarine system configuration. The raw (net) SE was 10.4 (8.67) b/s/Hz, thanks to digital spectral shaping. The Tx DACs operated at a record-low 1.15 sample/symb thanks to advanced anti-alias filters. The SEDP was 11,327 (bkm)/(s-Hz), highest for PM-64QAM.
