Abstract :
In this paper we prove the ability to deploy a WDM-PON of a 30 km standard single-mode fiber (G.652) carrying 160 Gbps data in downstream and 40 Gbps through the uplink. The method developed here is based on the comparison between two WDM-PON systems of four channels, where each one uses in its OLT own format of modulation. The first system uses the NRZ-ASK in the downlink direction, while the second uses the NRZ-DQPSK.
