You can do 10GE DWDM with 1x 10Gbps just fine :-)
Whether or not a DWDM system is N x <anything special> really depends on
the type of system - if it's just a passive MUX/DEMUX (half-transparent
mirrors with colour filters) you can do anything over it, as long as
the sender has proper coloured optics - like "1x GE, 1x 10GE, 1x 2G FC"
or such.
On an active DWDM system that actually understands the signals it's
transmitting (and possibly re-shaping to form), you depend on whatever
the system gives you.
