In a certain large facility, I have been asked to provide strong and reliable WAN circuit.
I am considering the deployment of a "fiber ring" served via two conduits, one conduit in the North and one conduit in the South of the data center.
My question is this:
1) If I deploy such fiber ring, what type of equipment I will need to terminate the OC-3 circuit? Is that the Cisco ONS series?
2) Bandwidth wise, my facility users would be satisfied with a 4.5Mbps (3xT1). However, with the fiber ring I will have a monster OC-3 (155Mbps) available. I am just wondering whether that is not an overkiller.
My question is, if my goal when deploying this fiber ring is to provide resilient and reliable WAN circuit, is there any other feasible and more cost effective way to provide this redundant WAN link other than the 'fiber ring'?
