Abstract:
> Micro-combs - optical frequency combs generated by integrated micro-cavity resonators – offer the full potential of their bulk counterparts, but in an integrated footprint. They have enabled breakthroughs in many fields including spectroscopy, microwave photonics, frequency synthesis, optical ranging, quantum sources, metrology and ultrahigh capacity data transmission. Here, by using a powerful class of micro-comb called soliton crystals, we achieve ultra-high data transmission over 75 km of standard optical fibre using a single integrated chip source. We demonstrate a line rate of 44.2 Terabits s−1 using the telecommunications C-band at 1550 nm with a spectral efficiency of 10.4 bits s−1 Hz−1 . Soliton crystals exhibit robust and stable generation and operation as well as a high intrinsic efficiency that, together with an extremely low soliton micro-comb spacing of 48.9 GHz enable the use of a very high coherent data modulation format (64 QAM - quadrature amplitude modulated). This work demonstrates the capability of optical micro-combs to perform in demanding and practical optical communications networks.

#4And even it that speed, I bet pre-roll ads on videos still end up buffering.

#5I like like the bottle neck in the future will be Harddrive/SSD file read/write speeds.
Honestly, I'd love to have my hands on a terabyte drive with 1TBps speeds.

#6This 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

#8Wasn't the last record (2014) of 255TBs?

#9> The highest commercial internet speed anywhere in the world is currently in Singapore, where the average download speed is 197.3 megabits per second (mbps).
what?

Yeah, this confuses me. Gigabit is available in several places in North America. I had to check the date on the article.. posted 20 hours ago. Yep. Still confused.
