The National Institute of Information Technology and Communications (NICT) has once again broken a new fiber speed record, reaching 1.02 petabits per secondthe speed is much higher than what they received 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 speed is made possible by a technology developed by NICT in 2021 that they previously achieved 319 Tbps. This, in particular, consists of a four-core fiber optic system. This frequency is three times higher than conventional cables, which are single core. In addition, the fiber cladding diameter used to make these four cores is exactly the same as that of a conventional fiber. This allows you to make the speed compatible with the existing infrastructure, as well as prevent degradation of reliability.

Standard-diameter 4-core MCF is attractive for early deployment of new spatial multiplexing (SDM) fibers in high performance long haul links as it is compatible with conventional cable infrastructure and is expected to have mechanical reliability comparable to standard single fibers. -mode fibers.

He mentions MCF in his report.

1.02 petabits per 51.7 km of fiber

To get speed 1.02 petabits per second over a 51.7 km fiber optic cable, a team of engineers from the National Institute of Information Technology and Communications had to increase the wavelength to 801 channels using a technology called WDM. As a result, they reached a common frequency 20THz, compared to the 14 THz they used in 2020, at which they were able to get 0.61 PTB per second. In the latter case, however, with a single-core cable.

Now, what does 1.02 petabits per second fiber have to offer? NICT guarantees that this power is equivalent to “10 million 8K streaming channels per second“. We also have to consider that 1.02 petabits would be equivalent to 104,000 Gbps.
