Researchers set a new record with 37.6 THz bandwidth and 402 Tb/s data rate in standard optical fiber, enhancing future telecom capacity.
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.A team of researchers has established a novel optical transmission bandwidth to enable a new data-rate record in optical fiber.
According to researchers at the Photonic Network Laboratory of Japan’s National Institute of Information and Communications Technology , the innovative technology is anticipated to significantly enhance the communication capacity of optical communication infrastructure, meeting the rising demand for future data services.driven by the growth of internet and data services has led to the rise of multi-band wavelength division multiplexing technology.
Wider transmission demonstrations have utilized bismuth-doped fiber amplifiers and Raman amplifiers, achieving up to 320 Tb/s data rates across 27.8 THz bandwidth in multiple bands.
