Actually, this CWDM seems to be Cisco specific and is incompatible with
DWDM,
looks like mostly because of the wavelengths used in this solution. Cisco
has a 2-slot
chassis that pretty much you populate with OADM or MUX cards. These cards in
turn
are crossconnected to switches by SMF and you use special CWDM GBIC's
for that. The GBIC's are what provides different lambda. These GBIC's seem
to be supported
on multiple platforms with proper IOS/CatOS ranging from 2900 to 6500
series.

Here's the link:

Looks like mostly plug-n-play as long as proper attenuation is considered
and you get the correct modules/GBIC's mix in there.
