De là à se rendre compte que les auteurs de ce pdf sont des vendeurs de solution FTTH, il n'y a qu'un pas.
Curieux de ne pas l'avoir précisé, pas que ça signifie que tout ce qui est indiqué est fondamentalement faux, mais il y a forcement un parti pris.
Et il y a Docsis 4.0 et/ou "Docsis dot Next" qui est sur le feu :

Speaking during a fireside chat and in a later interview here last week, Cox Communications Inc. 's executive director of advanced technology, Jeff Finkelstein, revealed plans to craft a futuristic DOCSIS spec for the next decade that would go well beyond DOCSIS 3.1 and Full Duplex to enable symmetrical broadband speeds as high as 30 gigabits per second or even 60 Gbit/s.

Referring to the proposed spec as "DOCSIS 4.0" or "DOCSIS dot Next," Finkelstein explained that it would support such high speeds by tapping into more of the cable HFC plant's available RF spectrum. Under this idea, also known as "Extended Spectrum DOCSIS," cable operators could use more than the 1.2GHz of plant spectrum that can now be leveraged for DOCSIS 3.1 or the 1.8GHz of spectrum envisioned for Full Duplex. (Note that plenty of operators aren't even using 1GHz yet, but the vision is there.)
Specifically, Finkelstein contemplates using at least 3GHz of spectrum for the new spec, nearly tripling the amount of bandwidth available, and potentially as much as 6GHz. (The coaxial cable physical limit is around 10GHz.)
"Think about it," he says, noting that cable keeps boosting the amount of RF spectrum it uses. "Why can't we go to 3GHz?
