Japanese researchers have set a new world record for internet download speeds, reaching 402 terabits per second (Tbps). This surpasses their earlier report of 321 Tbps from the earlier 12 months. To place this into perspective, 402 Tbps is equal to 402,000,000 megabits per second (Mbps), vastly outstripping typical dwelling web speeds, which are sometimes under 1,000 Mbps.
This exceptional pace permits downloading huge information, just like the 18+ GB sport Elden Ring, nearly instantaneously. The researchers achieved this breakthrough utilizing broadly accessible fiber optic cables, augmented by modern new applied sciences. These developments embody the first-ever O to U-band transmission system able to Dense Wavelength Division Multiplexing (DWDM) in customary optical fiber, coupled with custom-designed amplifier expertise.
This chart from the NICT press launch illustrates the numerous enchancment of this new report and the wavelengths utilized by researchers to attain it (Picture credit score: NICT).
The worldwide analysis crew was led by the Photonic Network Laboratory on the Nationwide Institute of Data and Communications Expertise (NICT) in Tokyo, Japan. Their methodology concerned enhancing knowledge sign amplification to maximise the transmission capabilities of fiber optic cables.
This included utilizing six doped-fiber amplifier variants mixed with Raman-amplification methods to span all low-loss transmission bands of silica fibers, attaining an unprecedented 37.6 terahertz (THz) of bandwidth over 50 kilometers of fiber optic cable.
No, you can not get it at dwelling
Regardless of the numerous developments, such excessive speeds are unlikely to be accessible to shoppers anytime quickly; Present {hardware} limitations imply that even top-tier gaming PCs can’t deal with or write knowledge at such excessive speeds. Nonetheless, the brand new transmission system represents a considerable leap ahead in knowledge switch capabilities.
The experimental nature of this analysis means that whereas shoppers gained’t see these speeds within the close to future, the findings may considerably affect the event of quicker web applied sciences, doubtlessly revolutionizing knowledge transmission charges sooner or later.
