TLDR
This paper is a tutorial reviewing research and development performed over the last few years to extend the reach of passive optical networks using technology such as optical amplifiers.Abstract:
We discuss recent progress in the development of optically amplified, long reach passive optical networks, which aim to significantly reduce network complexity and cost by integrating metro and access into a single, all-optical communication system.read more

Signal Remodulation of OFDM-QAM for Long Reach Carrier Distributed Passive Optical Networks
TL;DR: Three different colorless optical networking unit (ONU) architectures, electroabsorption modulator-based, reflective semiconductor optical amplifier-based and injection-locked Fabry-Perot laser diode-based ONUs, are tested and compared and the possibility of using OFDM for signal remodulation in LR-PONs is studied for the first time.
