Japan breaks Internet speed record by reaching 1.02 Petabits per second using fiber optics
A lab in Japan continues to break internet speed records, hitting petabits per second for the first time.
Imagine if you had an internet connection with a bandwidth capable of downloading 10 million movies at 8K resolution at the same time. That is what can be done with a fiber optic connection at 1 Pbps, that is, 1 Petabit per second.
A petabit is 1,000,000,000,000,000 bits, or what is the same, 1,073,741,824 Mbps. In other words, it is a connection 3.5 million times faster than the standard 300 Mbps we have now.
As incredible as this speed record is, it has been achieved using fiber optics compatible with the current one, so theoretically it could be implemented through current lines, although adapters and converters would be necessary.
It is the same equipment that in June 2021 reached 319 Tbps of speed. In one year they have tripled it. an amazing achievement.
These Japanese engineers have used 4-core fiber optic cables instead of one, and a 552-channel laser that fires at various wavelengths. These light flows are unified and amplified by amplifiers made of thulium and erbium.
The difference with respect to the experiment of a year ago is that the transmission bandwidth has increased to 20 THz, thanks to wavelength division multiplexing (WDM) technology.
As standard 0.125mm fiber optic cable has been used, it means that this technology is compatible with today's fiber optic installations.
Using signal modulation and amplification techniques, Japanese researchers have achieved a speed of 1.02 Pbps, transmitting 57 kilometers away. It is far from the more than 3,000 kilometers that reached 319 Tbps last year, but here we are talking about a speed three times higher.
Do not expect to contract 1 Pbps in your home for many years, but the important thing about this record is that it certifies that it is still possible to greatly improve current fiber optics, without having to completely change the cables.
