Hello Joshua,

 

Is 10GBase-R the underlying protocol used before the optical module?

  • Yes, 10GBase-R is the base physical layer that the transceiver implements electrically.

Also, does this mean that other optical modules, such as 10GBase-SR, are supported as well?

  • Generally, yes. The transceiver can work with other 10G optical modules such as 10GBase-SR, as long as they use the same line rate and comply with the electrical interface spec.

Regards,

Pavee

HI paveetirrasrie_Altera​ 

I have the Agilex 5E Premium Devkit. 

When I use a 10GBase-SR SFP+ module, it does not work. When I use a 10GBase-LR SFP+ module it starts to work. 

I think based off the GTS User Guide, Only 10Gbase-LR is currently supported!
