It depends if the DWDM gear is purely L1 or if it is doing OTN switching (it will be doing OTN if you are mapping 1 or more lower rate client side signals into 1 or more higher rate line side signals). The latter deals with framing and would have MTU limits. The former would have a 1:1 mapping from each client side wave to a each line side wave.
