Japan achieves 402 Tb/s data rate speed over 50 km with commercial optical fiber, by transmitting on the unused wavelength bands of 37 THz
New record shows potential high data throughput with no upgrade for current fiber optic infrastructure
The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. (Image credit: NICT)This demonstration also shows that the currently used wavelength division multiplexed technology (WMD) can cover all major transmissions and provide these speeds using unexplored bands.
