I have a pair of Mellanox switches, a MIS5030Q-1SFC and a MIS5022Q that I am looking to connect together using a pair of MFM4R12C-QDR transceivers, due to the distance involved. I had had this working in the past, but due to a relocation I need to source replacement fibre cables.
Should I be using an MTO/MPO crossover cable, rather than a straight through?
