replication between two data centers

[v.nastase]

Our company intend to use a replication solution between two data centers (200km distance between them) using DWDM transport and two switches MDS9216i on each site. Does anybody know what we need to complete the solution for data replication (atenuators,etc)? Is it viable this solution (any suggestions or white papers) ?

Thanks in advance for your help
