The problem with DWDM SFPs was their excessive power
consumption. While SFP MSA allows 1 W, the initial
DWDM SFPs required 1.3 - 1.5 W.

According to
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_data_sheet0900aecd80582763.html
these must be 2-nd generation modules, since at 3.3 V
the typical supply current is 200 mA and maximum 300
mA which means they are MSA compliant.

There's no reason why they shouldn't work on smaller
platforms - except for the fact that some show
commands will output "unknown" as module type until
the IOS is updated with their product numbers.
