Context Before

Cramming in approximately five thousand copper cables on the backplane at the Blackwell generation has introduced non-trivial reliability failure modes at scale.

Evidence

To double scale-up bandwidth

Context After

while staying on regular 200G SerDes would require the backplane to double to ten thousand copper cables: only further increasing the manufacturing complexity and likelihood of failure of the system.
