World record-shattering 402 TB data sent in a second via optical fiber | 37.6 THz optical bandwidth achieved by using 6 doped-fiber amplifier variants and Raman amplification, covering all low-loss transmission bands of silica fibers.
Researchers set a new record with 37.6 THz bandwidth and 402 Tb/s data rate in standard optical fiber, enhancing future telecom capacity.
The increasing demand for optical transmission bandwidth driven by the growth of internet and data services has led to the rise of multi-band wavelength division multiplexing (WDM) technology. Together with partners, NICT researchers created the world’s first O-to-U-band transmission system for DWDM using commercially available standard optical fiber and custom amplifier technology. The NICT team claims that high data rates were achieved using dual polarization(DP) quadrature amplitude modulation (QAM) with up to 256 symbols per constellation.
