Cisco 9300 SFPs

[yakulebak]

I have a Cisco 9300 SFP port GLC-LH-SMD-CURV 1000Base-LH-SFP SMF plugged in and on the other end I have an SPF 10GBase-ZR SFP plugged in , do these have to match on both ends exactly?

1.  Both ends must have the same wavelengths.  

2.  CURV is not supported.

Optical transceivers do not negotiate the link speed, so the transceivers need to be the same speed.

Aaaaaaaaaaaaaaaaaaaaand I so totally missed the speed.  
Thanks for the corrections, @Tom Randstrom.
