Comment on Researchers unlock fiber optic connection 1.2 million times faster than broadband
blarth@thelemmy.club 7 months agoIt’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.
