JAKARTA, AYOBEKASI.NET – Over the last few decades, the internet has contributed to most of human life. Nowadays, this technology is even more amazing, one of which is related to data transmission speed.
Reporting from Science Alert, Monday (24/8/2002), the researchers just set a new record for data transmission speed. They record an incredible speed of 178 terabits per second (Tbps). That’s about five times faster than the previous record set by a research team in Japan and roughly twice as fast as the best internet available today.
With the new speed, the internet can download around 1,500 4K movies of around 15GB in one second.
According to the scientists behind the project, the technology used to achieve the record 178Tbps get added to existing fiber optic pipes with relative ease.
Today’s internet is built on fiber-optic routes that use amplifiers to stop light signal deterioration. Adding new technology to an existing amplifier, which is about 40-100 km away, will require a fraction of the expenditure required to replace the actual fiber.
“Meanwhile, the latest cloud data center interconnection is currently capable of carrying up to 35 Tbps. We are working with new technologies that make more efficient use of existing infrastructure, make better use of fiber-optic bandwidth and enable a world-record transmission speed of 178 Tbps, “said electronics and electrical engineer Lidia Galdino of University College London in the UK.
To achieve this record-breaking speed, the team used a wider range of wavelengths (colors of light) than is normally used to transmit data. The bespoke system uses 16.8 terahertz (THz) bandwidth in a single fiber core, four times the 4.5 THZ used by some of their current infrastructure.
That bandwidth increase also requires a signal power boost and several different amplifier techniques are combined in this case. Hybrid systems carefully manage the properties of each wavelength, using a process called constellation formation to optimize signal transmission and avoid interference.
The combination of these techniques means that more information can be packed into the same space and sent more quickly. Without that information, it will get messy along the way.
The new 178Tbps record pushes the theoretical limit of what data transfer networks can take. The idea of taking more information through existing fiber-optic pipes is one that many scientists are exploring. They are trying to strike a balance between having the data shift as photons of light faster, without the photons interfering with each other.
The Covid-19 pandemic forces large numbers of people to work and socialize on the internet rather than face to face, the need for faster speeds and greater bandwidth has never been a more popular topic.
“Apart from the Covid-19 crisis, internet traffic has increased exponentially over the past 10 years and this entire data demand growth is linked to a decrease in the per-bit rate,” said Galdino.
