…now complete the circle, and run a 56k V.92(*) link over it. 8)
(* important, cuz despite claims to the contrary V.90 ain't at the Shannon limit, but V.92 is — kind of. See https://news.ycombinator.com/item?id=4344349 )

>It is tempting to attach a “dialup” modem to both sides, this would probably create the greatest modern day waste of a 100 GHz optical channel, given that it gives a final output bandwidth of ~40 kbit/s, and I assume this would probably confuse an intelligence agency if they were tapping the line.
Regardless of the fact that 48 kbps seems more likely, I'd really like to know the noise floor & SNR of that link
