Hi,

That sfp is for single mode fibre. Have a look at the following doc: https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/data_sheet_c78-455693.html

Thanks

As per my testings

LR and LR-S is a single mode Fibre ( SMF)(Do not use less short length cables when they are next to each other - we have observed some SFP burning and getting heatup_ use 3m to 5min cable)

LRM works for MMF and SMF
