With 26.2 Terabits Per Second, The MAREA Transatlantic Cable Breaks Internet Speed Record

An experiment on existing transatlantic fiber has achieved a record fiber optic cable capacity of 26.2 Tbps across more than 6,000 km of the Marea transatlantic fiber optic cable – the average transfer rate of the Marea cable is 9.5 Tbps. Infinera explains this data rate was obtained using WDM, implementing “multiple wavelengths on a single optical chip, so that we could squeeze the individual wavelengths closer together, and get more wavelengths on the fiber," and making "each wavelengths is transmitted as a set of subcarriers that also allows tighter spacing." The increase should help meet the growing needs for internet and cloud services.
