Agilex 5 GTS Supported Protocols

Hi Altera/Community,  I’m trying to better understand the protocols supported by the Agilex 5 GTS transceivers. In the user guide, it mentions that the supported protocol is 10GBase-LR. I wante...

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!

      Hello Joshua,

       

      I hope you've got your answer. Hence, I'll close the thread for now.

      If you have a new question, feel free to open a new thread to get the support from Altera experts. 
      Otherwise, the community users will continue to help you on this thread. 

       

      Thanks, Frank for the additional information!!

       

      Regards,

      Pavee

    Hello Joshua,

     

    I've rechecked with internal team here. And yes you're right. Based on UG, it supports based on what mentioned in User Guide.

    I had misconception that if it comply with electrical spec and line rate, it should work regardless. My theory was not right, silly me.

     

    Apologies for the confusion and I hope you've gotten your answer.

     

    Regards,

    Is there a list of qualified Transceivers available? If not, the above info is currently incomplete, as SFP+ and QSFP+ Transceivers are often vendor-locked. The Intel E10GSFPSR did not work in my case. Which transceivers are used by Intel(Altera) for qualifiying/testing the development board DK-A5E065AB32AEA ?
