Researchers discover how to transmit information at 661 Terabits per second

This article, published on July 2, 2018, in its Abstract makes the claim that the named researchers have been able to send a 661 Terabits of data, equivalent to the more than the total current internet traffic through a single-mode 30-core optical fiber. The content of the article was reviewed by arstechnica.com in an article entitled, "661Tbps through a single optical fiber: The mind boggles."

I am not going to attempt to explain how this is done, but I can suggest that, if this is the case, then the cost and time of transmitting data around the world are about to drop precipitously.
