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.
We demonstrate the possibility of laser sharing, using a multiple-output EDFA, to be adopted by central offices serving multiple PONs, showing compatibility with NG-PON2 standard.
We demonstrate 32 Gbps per wavelength upstream record capacity for a FDMA-PON over 37 km of installed fiber and 32 dB ODN loss, adopting an innovative ONU based on a reflective Mach Zehnder modulator.
We present a self-coherent reflective PON demonstrator, TWDM-PON compatible, running at 10 Gbps upstream bit rate per ONU using commercial DFB lasers, achieving 31 dB ODN loss at BER=10−3 over splitter-based PON in TWDM-like burst mode operation.
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.
A realistic uplink FDMA scenario for NG-PON2 is demonstrated with low speed electronics in the ONU (500 MHz) and high per wavelength aggregate capacity (12 to 15 Gbps). Stability over field deployed fiber is proven.
