Good night you could provide me the ITU-T standards for TDM, WDM, OCDM and OFDM, please.

Hi Heitor,
As far as I am concerned, OCDM and OFDM have not yet been standardized by ITU-T (although there are being considered to be used). In almost all standards including BPON, EPON, etc TDM has been used except for the last standard done in 2015, i.e. NG-PON2 which uses TDM for downstream and WDM for upstream.

For WDM ITU standard you mean the ITU-defined grid for wavelengths at 100GHz, 50GHz distance?
