as above.
i want to use the C95000-48Y4C 40/100G uplink port to use 25G transceiver.
reason, existing fiber cannot support 40/100G, so thinking to use back existing fiber to connect with 25G instead of 10G.
Solved! Go to Solution.

Hello @Charlie Grey ,
I have used it on Nexus 3000 uplink ports that using speed 10000 interface command creates an interface like eth1/49/1 and then you install an SFP+ in the converter.
Hope to help

the links you provide are from third party cisco compatible.
i am asking if Cisco selling the convertor?

C95000-48Y4C 40/100G
Personally not tested this converter, but this clearly says 40/100GB - do you think this can go below 40Gb ?

CVR-QSFP-SFP10G
allow the 40/100G ports to use 10G transceiver. why not?

Hi Charlie,
The uplink ports are fixed 40/100.
From the installation guide:
Fixed QSFP uplink ports that support 40G/100G connectivity on C9500-24Y4C and C9500-48Y4C switches.

in that case, where should this CVR-QSFP-SFP10G be used?

CVR-QSFP-SFP10G - can be used where they have compatable with 10GB interface QSFP ports
Fixed 40/100 - only can be used for 40 or 100GB.

Yes, CVR-QSFP-SFP10G can use on C9500-48Y4C 40/100 G uplink ports to convert to use 10G transceiver.

100 and 25G use similar PAM4 encoding and light sensitivity. If 100G doesn't work, 25G will likely not or will and would be problematic. The fall offs are very close when talking singlemode fiber for 25, 40, and 100 (25 and 100 usually performs better than 40, but not each other). Interested to hear how this works out.
