By the way, 31Tbit really isn't that fast, 200Gbit/wave * 96 waves (a hair under 20T) is in field deployment using kit from the major DWDM vendors (such as ALU). Whether there's any networks actually populate their links that big I doubt, but as an example, the last time they released numbers (several years back) Comcast had inter-city links of 800g in the US, they're likely up to at least 2-3T these days.
I don't know how fast the fibre connections are, but Comcast are giving me 300MBPS downstream over Docsis 3, and achieving it, according to my speed tests. This is a fairly recent upgrade. If I had a Docsis 3.1 modem, it might be faster.
