Dear All,
We are plan to do the RING for our infrastructure with cisco ME 3600X Switches but we have issues with Fiber cable. We have only one core fiber for transfer and receive. I see one cisco SFP-10G-BX40D-I and SFP-10G-BX40U-I can support single strand of fiber. One is for Upstream and one is for DownStream. We have 3 POPs. I concern if link between SW1 and SW2 down, the , can the traffic go through from SW1 to SW2 via SW3 or not? Can the traffic send from downstream to upstream or not?
Thanks for your kindly support
