We demonstrate distributed Raman amplification compatible with the wavelength plans and rates defined in ITU's specification for TWDM PON. We report downstream and upstream gains of 9.8 dB and 8.6dB, respectively, for a 42-km, 8-wavelength TWDM PON with 80-Gb/s symmetric capacity and 1:128 split. Raman gain and system performance are also reported for 21-km and 10-km feeder lengths.
