In the case of PON, WDM is used to dedicate wavelengths on the strand for
different purposes - ingress, egress, RF overlay (as someone else
mentioned), TDM voice etc.
You could deploy 2 or 3 strands and get more bandwidth to the customer,
using perhaps less expensive hardware, or you could maintain fewer strands
in the ground and depend on equipment manufactures to maintain an adequate
growth in bandwidth capabilities.
Neither approach is going to work for everyone.
