Scientists on Monday said they have achieved a world record for high data transmission over 75 kilometres of standard optical fibre, using a powerful class of micro-comb called soliton crystals.
"This is one of the most efficient transmission systems implemented in a standard telecom network, given the record amount of information that can be encoded and propagated in an optical fibre with minimum loss of data," said Professor Roberto Morandotti, of the Institut National de la Recherche Scientifique (INRS) in Canada.
Telecommunication networks use many different frequencies, or colours, to transfer as much information as possible, the researchers said.
Current networks need typically
