Cisco SFP-10G-LRM module

The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade Multimode Fiber (MMF). To make sure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4. For additional information on mode conditioning patch cord requirements please see: https://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html.

The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF, G.652).

However, within Cisco's Optics-to-Device Compatibility Matrix (https://tmgmatrix.cisco.com/?dr=10&npid=4301), that SFP is not listed for any 9300 model except for:

No, OM1 typically can support 10 Gigabit Ethernet at lengths of up to 33 meters.

-hope this helps-

Thank you for your ansewer.

If the C9300-24U-E supports the C9300-NM-8X network module, and as as latter supports the SFP-10G-LRM, the answer should be yes.

BTW, the C9300X-12Y-E supports 25 Cisco optical transceivers, but again, the SFP-10G-LRM isn't listed as one of them.  However, there's a difference between supported and whether it will work or not.  Much like 3rd party optics, it may work just fine, but if you do have a problem with it, Cisco won't support it.

Thank you for your answer.
