Seems strange they are using cat 6 cable, which is specified/characterized/tested to 500 MHz, at 2500 MHz for gen 2. Loss is probably not an issue because I see a redriver on the adapter card, but this doesn't seems like a robust solution. I suspect there is a lot of variation in cat 6 cable behavior (across vendors, cable, crimping) at 2.5 GHz.
