Abstract

In a first system configuration, a dedicated 50G-PON module was incorporated into the OLT, seamlessly coexisting with commercial G-PON and XGS-PON. The coexistence of the three generations of PONs is done here without adding any loss (filter) in existing ODNs, the 50G-PON being inserted on a 2:2 splitter at the CO. Furthermore, the possibility to extend the reach and place the 50G-PON OLT in a remote CO is evaluated. The second system uses a MPM at the OLT that includes the three PON generations. To our knowledge, this is the first full G-PON, XG(S)-PON, 50G-PON system prototype that provides an optical budget of 29 dB, and we demonstrate the possibility of extending the budget to 35 dB using SOAs.
