Gigabit optical access using WDM PON based on spectrum slicing and reflective SOA

We report on the experimental results of a low cost 40 users WDM PON providing 1.25 Gbit/s per user. We focus on the upstream path using spectrum slicing of a SLED at the OLT and remote modulation at the colorless ONU with a reflective SOA. Bidirectionnal transmission over 20 km is demonstrated.
