It can change everything.
We are waiting for the information revolution.
In Japan, engineers broke the world record for the fastest Internet speed, achieving a data transfer rate of 319 Terabits per second (Tb / s). The new record was broken on a fiber line with a length of more than 3,864 miles (3,000 km). And most importantly, it is compatible with modern cable infrastructure.
It can change almost anything.
New data transmission method splits signals into different wavelengths
Please note: We cannot stress enough how fast this transmission is. That’s nearly double the previous record of 178 Tbps in 2020. And it’s seven times faster than the previous record of 44.2 Tb/s set by an experimental photonic chip. NASA itself uses a relatively primitive speed of 400 Gb / s, and the new record is much higher than what ordinary consumers can use (reaching 10 Gb / s for most home Internet connections).
As if there was no limit to this magnificent achievement, the record was broken with an optical infrastructure that already exists (but with a few advanced additions). Instead of a traditional standard core, the research team used four “cores” with glass tubes encased in data-transmitting fibers. The signals are then split into several wavelengths that are sent simultaneously and a technique called wavelength division multiplexing (WDM) is used. To transmit more information, the researchers used a rare “third band” that widens the distance through several optical amplification technologies.
The new system starts the transmission process with a 552-channel comb laser fired at different wavelengths. It is then sent via dual-polarization modulation so that some wavelengths create multiple strings of signals before others – each, in turn, routed to one of the four cores within the fiber optic. Data transmitted through this system travels 43.5 miles (70 km) of optical fiber until it reaches optical amplifiers to amplify the signal for long journeys. But there’s something more complicated: before it moves into the signal path, it goes through two new fiber amplifiers with thulium and erbium-doped in a traditional process called steering amplification.
The world’s information infrastructure awaits a revolution
The signal sequence is then sent to another fiber optic segment, and then the whole process is repeated, allowing the researchers to send the data over a distance of 3,864.7 miles (3001 km). It is very important that the new quad-core optical fiber has the same diameter as the traditional single-core fiber and strengthens the protective coatings around it. In other words, the new method of integrating into existing infrastructure will be simpler than other technological repairs to society’s information systems.
This is what really broke the new data transfer speed record. Researchers in Japan have broken the 2020 record with a new engineering method that can integrate modern artificial optical infrastructure with minimal effort. We are approaching the age of twenty and in the early 2020s the Internet will look barbaric in terms of signal speed and data transmission. An exciting time to live.
