Minimization of amplified spontaneous emission noise in upstream SuperPON 512 ONU, 10 Gbit/s

We demonstrated the effect of presenting optical band pass filter for point to multipoint architecture such SuperPON. The position of optical filter and the range of optical filter bandwidth to minimise amplified spontaneous emission noise for upstream SuperPON with 512 ONU at transmission speed of 10 Gbit/s is explored.
