Optimal trade-off for a bidirectional single-fibre single-wavelength TDM-PON rSOA-based ONU
, 2013 In this paper, an optimal trade-off between the Optical Distribution Network (ODN) power budget and the upstream optical Signal-to-Rayleigh Ratio (US-oSRR), for a Single- Fibre/Wavelength TDM-PON rSOA-based ONU network is presented.

1.25-3.125 Gb/s per user PON with RSOA as phase modulator for statistical wavelength ONU
We report a new scheme to support, cost efficiently, ultra-dense wavelength division multiplexing (UDWDM) for optical access networks. As validating experiment, we apply phase modulation of a reflective semiconductor optical amplifier (RSOA) at the ONU ...
