Quite a bit I’d say, particularly in WAN. It’s an easy and excellent go-to for line rate encryption along waves and some transparent layer 2 services state they support it but haven’t had an opportunity to test personally. Double check the implementation for continuation of rolling keys and so forth to ensure your expectations are met.
On the DWDM side, expect to add between 0.3W of energy @ 100G, and 0.6W @ 400G, when encryption is enabled.
Something to keep in mind if power and/or thermal management are crucial for you.
