It says they transmit over a 37 core fiber, so 1.9 / 37 is about 53 terabits per second? Is it common for optical phys to encode/decode at this rate?

- Sporktacular 4y agoUnless I misunderstood, this is the number that matters. The 1+ Pb/s is like giving a headline grabbing statistic that highway can carry 10 million passengers per hour and then adding below that it's a 100 lane highway. The advancement seems that the de/multiplexing is done on a single module at each end.
- rassibassi 4y agoThey also multiplex across +200 channels across wavelength (wavelength division multiplexing). Not sure what the baud rate of a single channel was in their experiment but probably between 32-80Gb which is common for the lab equipment at Universities. The industry is knocking on 100-400Gb where for the actual decoding and signal processing there is massive parallelism applied to reduce the rate even more
