How much of this article is written by the author instead of Cadence itself? The use of certain adjectives to describe how excellent some numbers are seems weird coming from a generic news editor. I don't know if I can trust this is as groundbreaking as it sounds.

Also, very sparse on technical details. Even basics are missing, like - what's optical signal like? CWDM? multiple polarizations? QAM? How many fibers?

I mean - one can build a 16-fiber, CWDM16 monstrosity that would transport an 8x 128GT/s PCIe using mere 8 Gbit/s per channel - all of which is technology that was "groundbreaking" circa 2005.
