Scientists Create 12000 km Fiber Optic Cable Data Transmission Record

Recently, researchers at the University of California, San Diego, have demonstrated ways to enhance data transmission and eliminate crosstalk over long-haul fiber optic cables. This means that expensive electronic regenerators are no longer needed to keep the signal steady.

The results of this research will result in faster and cheaper transmission networks, especially over long distance international submarine cables.

This research demonstration is achieved by using a frequency comb as a similar coordinating conductor. The frequency comb is used to synchronize the frequency variations of different optical streams, thereby compensating for crosstalk interference in advance, while crosstalk interference is also eliminated.

Demonstration results show that the research team can enhance the transmission 20 times, setting a new record in 12000 km fiber optic cable data transmission. The data remains intact on the other end, all without the use of repeaters, using only standard amplifiers.
