Distributed Raman amplification in a 8 x 10-Gb/s, 40-km, 1:128 TWDM PON
31 October 2016
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.
