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 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...
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 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 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 present our recent results on coherent detection technologies applied to upstream transmission in reflective PON, comparing them to other existing architectures and showing a higher resilience to spurious reflections when compared to direct detection.
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.
