Hi,

I am Farabi supporting this case. May I request further information like any screen shot of waveform of SFP or indication that showing intermittent transmission failures. We can start our debug form that point.

3. If you use short cable (less than 10m) is the intermittent failure still persist?

regards,
Farabi
