SFP-10G-T-X= Compatibility with C3850-24XS

[alejandro_pardo]

A client has a switch C3850-24XS and I did not found documentation of compatibility with SFP-10G-T-X=, maybe because the SFP+ is a recent product.

Can somebody help me to confirm if SFP-10G-T-X= works with C3850-24XS Switch?

Thanks for your support.

Are you sure that is the correct part number for the SFP+?

See the compatibility list for all the supported 10Gig SFP+s

I found this Updated:September 27, 2021 https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/q-and-a-c67-743938.html

Does not exist mention about C3850 family, I think because are old swiches...

Have a look at table-12 and see the supported optics:

Depends on the firmware of the switch.  

I have seen some people deploy non-Cisco branded SFP-10G-T re-flashed as GLC-T/GLC-TE but they support 10 Gbps copper.
