Experimental demonstration of 10 Gbit/s upstream transmission by remote modulation of 1 GHz RSOA using Adaptively Modulated Optical OFDM for WDM-PON single fiber architecture

Abstract

We experimentally demonstrate the use of AMOOFDM format for remote modulation of low-bandwidth RSOA as a cost effective solution for 10 Gbit/s upstream transmission in 20 km single fiber WDM-PON architecture.

Next Generation of Optical Access Network Based on Reflective-SOA

“…Active research on high bit rate RSOA has led to 10 Gbit/s operation with EDC (Torrientes et al, 2010), OFDM (Duong et al, 2008) or electronic filtering (Schrenk et al, 2010). Bandwidth improvement to 7 GHz small-signal bandwidth with dual-electrode devices have been obtained but no large signal operation .…”

13 Gbit/s WDM-OFDM PON using RSOA-based colourless ONU with seeding light source in local exchange

“…It is desirable to operate the RSOA-based ONU .10 Gbit/s for the future WDM-PON. Recently, there have been several demonstrations to increase the RSOA operation speed to 10 Gbit/s by using adaptively modulated optical OFDM (AMOOFDM) [2], offset optical filtering and electronic equalisation [3], special design structure [4], or adding a delay interferometer [5]. In this Letter, we demonstrate a WDM-PON using a commercially available 1.2 GHz bandwidth RSOA-based ONU, which can be operated up to 13 Gbit/s.…”

“…Optical carrier distribution with a colourless optical networking unit (ONU) is one of the cost-effective implementations of the WDM-PON [1]. The reflective semiconductor optical amplifier (RSOA)-based ONU is important for the WDM-PON owing to its compact size and low power consumption [2][3][4][5]. Recently, using optical orthogonal frequency division multiplexing (OFDM) modulation in PONs has attracted much attention [6].…”

Self-Coherent Reflective Passive Optical Networks

“…In order to increase the upstream data rate up to 10 Gbit/s in such an architecture, using this low-bandwidth devices, different approaches have been proposed by research groups, like the use of optical filtering and electronic equalization [23][24][25] or the adoption of advanced modulation formats [26].…”
