Hi,
Wavelength Division Multiplexed PON
There are many concepts concerning how WDM-PON may
be implemented and several were studied in the context of
NG-PON2. They are Externally seeded WDM-PON,Wavelength re-use WDM-PON , Tunable WDM-PON, Ultra-dense Coherent WDM-PON.
WDM PON uses multiple wavelengths to
provision bandwidth to ONUs, while OFDM PON employs a number of orthogonal
subcarriers to transmit traffic from/to ONUs.With the WDM or OFDM technology,
these PONs are potentially able to provide higher than 40Gb/s data rate and even
Tera bps data rate. due to the high system cost.
WDM PON allows each user being dedicated with one or
more wavelengths, thus allowing each subscriber to access the full bandwidth
accommodated by the wavelengths.

Here are links for WDM-PON as:
