Danish university transfers data at record-breaking 43Tbps over a single fiber

The Technical University of Denmark has set a new record for transmitting data over one channel: 43 terabits per second. It beat the old record, which belonged to the Karlsruhe Institute of Technology in Germany, by a margin of 11Tbps.

One of the main reasons the record was possible is a new type of fiber developed by Japanese operator NTT. It's made up of seven glass threads or cores instead of the single one used in standard fibers. This allows operators to move more data without increasing the size of the fiber.
