back to article Japan's NTT claims it's built 1.2Tbit/s optical comms that sip power

Japan's NTT Corporation claims it has developed technologies that allow data transmission at 1.2Tbit/s per wavelength in an optical system. As today's commercial kit delivers 100Gbit/s per wavelength, this is quite a breakthrough. But wait, there's more: NTT reckons its tech reduces power consumption to less than 10 percent …

    This will speed up fax transmission rates for sure!

      Fax transmission rates are measured in kilobits per second. You'd need a rack of ~30 million fax machines to max out a 1.2Tb/s connection.

        I guess I should have used a Joke Alert instead of Troll Face. My bad.

    Scpetical? No way! 1000km!?

    I was expecting there to be a catch in all this since NTT doesn't mention the ACTUAL distance record they broke, but after a bit of ducking (DDG) I find that the the distance record for 800Gbps was 970km in September 2020 [0] and that has probably been surpassed since, so this new technology from NTT is definitely a significant advance - especially as it seems to be out of the R&D stage and looking for scaling into production.

    That's impressive!

    See title.

    more advanced real time tracking and monitoring with faster phishing distribution. Might even make streaming reliable at peak times. Sounds too good to be true.
