DWDM 10ms failover

I’m looking for some real world feedback on 10ms DWDM failover times from Omaha to Denver on 10Gbps transmission waves. I have seen several documents that report 10 ms failure detection time but I suspect the failover mechanism takes some time to react and propagate the failed state across multiple nodes in what is probably at least 600 mile cable routes with multiple nodes along the way. Is that kind of performance something we could realistically expect?
