Thanks for your reply. In that case all we have to worry about is the SFP type, based on do we need 1G or 10G?

Thanks for taking out time in replying Philip. We have to check the fibre run specs but apparently it is a very old infrastructure. So I am suspecting it will be OM1 as the patch leads I looked are mostly orange colours which used to be with the OM1 environment if I am not mistaken? With that in mind, going by the SFP datasheet, shouldn;t the LRM's be the best bet as they can stretch upto 220m on OM1 compared 26m on MA-SFP-10GB-SR? And in regards to switch side, are you suggesting we should be safe with 425-16? Those 10G slots are good to run on 1G if we use MA-SFP-1GB-SX?? And the same goes with the MS250 uplink module? Thanks.

Hi all, We have a requirement to deploy Meraki MS425-16. However we are not sure the fibre run connecting the MS250 switches (from different places) to this core can support 10G. So in an event if we have to go back to 1G fibre connection, I was not sure about the following: The MS425-16 supports 1G? MA-SFP-10GB-LRM can run at 1G? I think we will have to use 1G SFP's. The MS250’s uplink can support 1G Uplinks. If anyone has used the similar environment, can you please confirm if the above arrangement will work in 1G backbone? Thanks, Mohit
