   I've wondered if one could shoot with DWDM 10G optics into two channels
   of a CWDM mux.  For example, by connecting DWDM channel 359 (center
   1530.33 nm) and 334 (center 1550.12 nm) to the 1530/1550 filters of a
   CWDM mux with 20nm spacing (+/- 6.5nm pass band).  Might that support
   1x10gig + 3x1gig on a single strand, or 2x10G + 6x1G on a pair?  (and
   no, I haven't tried it).
