Is anyone knowledgable on the implications of the underlying tech once it gets commercialized? Obviously things like game streaming would be improved.

#22This is not directly internet related. The original title is better: > Ultra-dense optical data transmission over standard fibre with a single chip source As a compromise, I'd propose: > 44.2 terabit/s optical data transmission over standard fibre with a single chip source
Much better, because what the heck is "internet speed". The most sensible definition to me is payload over IP protocol possibly on an existing commercial link. That's the only way I see relation to internet and the internet.

We will be able to make comments complaining about bloated JavaScript libraries at lightning speed.

> As of early 2010, researchers have been able to multiplex over 400 wavelengths with the peak capacity of 171 Gbit/s per channel, which translates to over 70 Tbit/s of total bandwidth for a single fiber link!
So why/how is 44 Tbps an improvement?

Aren’t gamers primarily concerned with latency rather than speed?

#26Wasn't the last record (2014) of 255TBs? https://www.extremetech.com/extreme/192929-255tbps-worlds-fa...
That was over 1km utilising 7 cores. Typical fibre plants use one core per direction (transmit / receive). This is over 75km utilising a single core per direction. IE this is actually something that has potential to be deployed in the world without having to replace all the existing fibre plants that already exist (eg undersea cables)
It would be interesting to see if EDFAs also do not require retrofit.

#28Given the cost of laying fiber lines across the ocean and this tech (appears) to double the capacity of an existing line, why would there not be a push to get this into use, what am I missing?

The improvement here seems to be "single chip" source.

They said game streaming, which makes me think s/he's talking about things like Twitch and Mixer, livestreaming platforms that do depend on throughput for high quality video.
