301 terabits per second (new record) on existing infrastructure

In the average American home, the download speed averages 242 Mbs and is considered a pretty decent internet connection.

Researchers at But Aston of the UK recently managed to catch 1,2 million times that rate using a simple fiber optic cable. This is a new record for certain wavelength bands.

The international team achieved a data transfer rate of 301 terabits, or 301.000.000 megabits per second, gaining access to new wavelength bands that are not normally accessible on existing optical fibers. According an Aston University publication, you can think of these different wavelength bands as different colors of light emitted through a standard wire.

Commercially available fiber optic cabling uses what are known as C and L bands to transmit data.

However, by building a device called an optical processor, the they could access the unused E and S bands.

"In recent years Aston University has developed optical amplifiers that operate in the E band, which is next to the C band in the electromagnetic spectrum, but is about three times wider," said Ian Phillips, creator of the optical processor.

“Prior to the development of our device, no one was able to properly mimic them a of zone E in a controlled manner."

But as far as new technology goes, the processor was basically an experiment for the team.

"In general, the sent over an optical fiber like an Internet connection in the home or office," Phillips added.

What is particularly impressive and promising about the team's achievement is that no new fiber optic lines are needed to reach these incredible speeds.

Most existing optical cables are technically capable of reaching E and S bands, but lacked the equipment infrastructure to do so. With further improvement, Internet providers could increase standard speeds without repairing current fiber infrastructure.
