NEC and NTT Successfully Trial Revolutionary Submarine Cable Technology

Japanese corporations NEC and NTT have successfully trialed a revolutionary submarine cable technology set to drastically enhance internet speeds under the sea. The experiment transmitted hundreds of terabits across a 7,280km distance, made possible through a sophisticated algorithm. This innovative solution uses a 12-core multicore fiber, significantly enhancing existing single-core fiber used in submarine cables. The addition of more cores presents challenges, but NEC and NTT have developed solutions to overcome these issues. Moving forward, the aim is to commercialize the research, potentially contributing to a high-capacity optical submarine cable system and terrestrial core network. The research team estimates that such systems could operate at hundreds of terabits per second, potentially heralding the advent of petabit per second class submarine cables.
