The National Institute of Information Technology and Communications (NICT), has once again broken a new fiber optic speed record by reaching 1.02 petabits per seconda speed much higher than what they obtained in 2021, which was 319 Tbps and which allows, for example, to transmit up to 10 million channels in 8K resolution per second.
This amazing fiber optic speed has been possible with the technology that the NICT developed in 2021, and with which they previously obtained speeds of 319Tbps. This, in particular, consists of a four-core fiber optic system. It is a frequency three times higher than conventional cables, which are single-core. The fiber cladding diameter used to obtain those four cores, moreover, is exactly the same as that used in conventional fiber. This makes it possible to make speed compatible with current infrastructures and also prevent reliability from being compromised.
The standard cladding diameter 4-core MCF is attractive for early adoption of new spatial division multiplexing (SDM) fibers in long-distance, high-performance links as it is compatible with conventional cable infrastructure and is expected to have mechanical reliability comparable to standard single-mode fibers.
Mention the MCF in your report.
1.02 petabits in 51.7 km of fiber optics
To get the speed of 1.02 petabits per second sent via a 51.7 km fiber optic cable, the group of engineers from the National Institute of Information Technology and Communications had to increase the wavelength by up to 801 channels with a technology called WDM. As a result, they reached a total frequency 20THz, compared to the 14 THz one they used in 2020 and with which they were able to obtain 0.61 Ptbs per second. In the latter case, however, with a single core cable.
Now, what can fiber optic speeds of 1.02 petabits per second offer? The NICT ensures that this power is equivalent to “10 million 8K streaming channels per second“. We must also take into account that 1.02 petabits would be equivalent to 104,000 Gbps.
