The National Institute of Information and Communications Technology (NICT) recently achieved a significant breakthrough in optical communications, successfully transmitting data at an unprecedented rate of 336 terabits per second (Tb/s) using a single light source. This was accomplished by combining ultra-dense wavelength division multiplexing (WDM) across multiple bands, utilizing advanced modulation techniques, and leveraging sophisticated spatial multiplexing. This achievement highlights the potential for developing future high-capacity, energy-efficient optical networks, setting a new standard for data transmission rates over optical fibers.
