Demonstration of Wavelength-Shared Coherent PON Using RSOA and Simplified DSP

We investigate the role of a reflective semiconductor optical amplifier (RSOA) in a fully coherent wavelength-shared passive optical network architecture, based on self-coherent upstream (US) and self-homodyne downstream (DS) detection schemes. We present a proof of concept experimental study, demon...

Description
Summary:We investigate the role of a reflective semiconductor optical amplifier (RSOA) in a fully coherent wavelength-shared passive optical network architecture, based on self-coherent upstream (US) and self-homodyne downstream (DS) detection schemes. We present a proof of concept experimental study, demonstrating 32-dB loss budget over a 30-km fiber link, operating at 9.4-Gb/s DS and 750-Mb/s US effective rates with 7% forward error correction and 8b/10b US overheads, respectively. This was achieved using simplified digital signal processing and a low-cost, off-the-shelf RSOA with 18-dB gain and 1-GHz modulation bandwidth.
