I would suggest you talk to some other vendor as well, specifically a vendor
how cares about passive solutions.

I may be wrong, but my impression is that Cisco is EOL'ing the entire
*passive* CWDM and DWDM gear. Whens the last time Cisco shipped
a new *passive* CWDM or DWDM product?

It is probably in their commercial interest to promote their active gear.

Careful with vendors advice.
