Ideally, you should use a "breakout optic" if supported by your device: it plugs into an 40Gbps port and delivers 4x10 Gbps via a MTP/MPO "breakout cable" (MTP/MPO at one end, change from one fat cable to 4 duplex cables somewhere in the middle, 4xLC duplex at the other end). Optic : https://www.fs.com/fr/products/37016.html (or the "riskier" 1km version : https://www.fs.com/fr/products/48276.html ) Cable : https://www.fs.com/fr/products/80240.html An "10G into 40G port adapter", as previously suggested could also work. > NAME VALUE > --------------------------------- > SwPort 1 > Status PRESENT > Valid True > Vendor FiberStore > Model SFP-10GLR-31 > Serial-Number G1804021292 > Type SFP > Module-Type 10G_BASE_SX > Media-Type FIBER > Module-Capability F_10G > Length 255 > Length-Description > > which i am swapping out for the delta 9020 At some point I can see "10G_BASE_SX" which is a little confusing, since "Base SX" is 1G on multi-mode fiber, in conflict with "SFP-10GLR" which is 10G on single-mode. It really is a 10G-LR, right ? > so i am look at something such as https://www.fs.com/products/30900.html > except i do not understand active/passive, AOC1M, etc Don't ! DAC (usually copper-based) and AOC are cables with optics at each end (if you can call a "copper optic" an "optic"....). Cable cannot be detached from the *SFP*.
