right, so DWDM alien wave requirement then. That's very non-portable and 
kit specific.

Depending on the application, you might be better off ditching the 
requirements that they're imposing and simply using 100G transponders 
(i.e. 100G as a service).  Or something like the smartoptics open line 
system with PAM4 QSFP28 transceivers.

It really depends on what's between you and the other end.  D/F has 
simple options open for single 100G. If you're connecting into something 
more complicated, it can get messy and expensive.
