Abstract :
We experimentally demonstrate extremely high ODN optical power budget in self-coherent reflective PON at 1.25 Gbit/s (upstream), allowing more than 38 dB attenuation in the ODN after propagation in 80 km installed fibers. This was obtained by optimizing R-SOA parameters at the ONU, (optional) Faraday rotation and DSP at the OLT.
