It depends what it is.

"The standard 10 GbE LAN has a data rate of 10.3125 Gbps. In the OTU1e and
OTU2e mapping schemes, the full 10.3125 Gbit/s is transported including
the 64B/66B coded information, IPG, MAC FCS, preamble, start-of-frame
delimiter (SFD) and the ordered sets (to convey fault information)."
So with this kind of transport network, you should not have MTU limit
because it's bit transparent.
But then again, this is not "DWDM wave", this is a transport network of
capacity. It can run at multiple speeds, and the whole talk about "waves"
is typically a misnomer because it seldom is.
