this has been clear for some time. The signal gymnastics and distance limits associated with the newest PCIe standards are increasingly intimidating!

@AlanSill I would think that with extended reach we will get higher latency - isn’t a bit contradicting?

@shefys Signal propagation within circuit boards gets increasingly limited at higher frequencies due to capacitance. Optical is not for reach, but to get past this limitation.

@AlanSill ah, I was thinking more in CXL context. Board level make sense - signal integrity is a real challenge for sure
