New ContributorI am able to enable DFE adaptation when using the transceiver toolkit on my C10 GX. I know it is working properly because before enabling DFE adaptation I have error bits (my error rate is somewhere along the lines of 1E-4), and after enabling DFE adaptation my error rate is 0. If you could help me enable it without having to use the transceiver toolkit, I would be greatly appreciative.
Regular ContributorHi,
Sorry for delay. There seems to be some glitches in the system which causes some issues for me to add post.
Thank you for reaching out. Based on my understanding on the current observation, the Transceiver Toolkit seems to be accessing internal DFE registers, which are not formally exposed for user access. Since DFE adaptation is not officially supported, I’m unable to enable this feature.
If you would like to explore this further, I recommend engaging your local sales representative, who can work with our factory team on your request. Please note that this process typically requires sufficient business justification.
Regarding your PMA analog tuning in Toolkit, just to check, if you perform auto-sweep with the equalization features (apart from DFE), does it help to find an optimal settings with low BER?
Feel free to let me know if you have any questions or need additional clarification. Thank you for your understanding.
Regular ContributorHi,
