Agilex-5 supported Transceivers

I am currently evaluating the capabilities of the Altera Dev Board DK-A5E065AB32AEA. As most SFP+ and QSFP+ Transceivers are often vendor-locked, is there a list of qualified Transceivers available?...

    It will not work that way. The test with external loopback assumes that you have attached a loopback plug to either QSFP0 or QSFP1, looping back TX to RX for each lane internally within the QSFP chosen. You have looped back QSFP0 to QSFP1. You have to get a loopback plug or you can only use internal loopback with this test.

Hi,

Thank you for your response. There is no option to modify the configuration in the BTS front-end.
Having considered the 25G default setting, another attempt was made using the transceiver 25G which is marketed as compatible with Nvidia. The exact product is SFP-25GSR-85 (compatible with Nvidia Mellanox). This also did not work.

Also, attempts with QSFP-SR4-100G(compatible with Nvidia Mellanox) along with the example sof config using BTS also did not succeed.
