Distances though? I've seen similar breakthroughs in the past but it was only good for networking within the same room.
It's optical fiber so it's good for miles. Unlikely to be at home for decades but telcos will use it for connecting networks.
Optical fiber is already 100 gigabit so the article comparing it to your home connection is stupid.
So the scientist improved current fiber speed by 10x, not 1.2 million X.
It’s much more than just 100Gb/s.
A single fiber can carry over 90 channels of 400G each. The public is mislead by articles like this. It’s like saying that scientists have figured out how to deliver the power of the sun, but that technology would be reserved for the power company’s generation facilities, not your house.
You mean with 50 GHz channels in the C-band? That would put you at something like 42 Gbaud/s with DP-QAM64 modulation, it probably works but your reach is going to be pretty shitty because your OSNR requirements will be high, so you can't amplify often. I would think that 58 channels at 75 GHz or even 44 channels at 100 GHz are the more likely deployment scenarios.
On the other hand we aren't struggling for spectrum yet, so I haven't really had to make that call yet.
