In a groundbreaking achievement, an international research team led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT) has shattered previous data transmission records. The team, headed by Dr. Hideyuki Tokuda, demonstrated an astonishing aggregate optical transmission bandwidth of 37.6 THz, resulting in a new data-rate record of 402 terabits per second using standard commercially available optical fiber.
Unprecedented Optical Transmission System
This record-breaking success was made possible by the development of the first optical transmission system capable of covering all transmission bands (OESCLU) within the low-loss window of standard optical fibers. The system utilized a combination of advanced amplification technologies, including six types of doped fiber optical amplifiers and both discrete and distributed Raman amplification. Additionally, novel optical gain equalizers enabled access to new wavelength bands, previously unused in current systems.
Revolutionizing Data Communication
The innovative technology unveiled by this research is poised to revolutionize the optical communication infrastructure, significantly expanding its capacity to meet the ever-growing demands of future data services. This breakthrough underscores the potential for dramatic improvements in how we handle data transmission on a global scale.
Presentation at OFC 2024
The details of this groundbreaking experiment were presented as a post-deadline paper at the 47th International Conference on Optical Fiber Communications (OFC 2024). Ben Puttnam presented the findings on Thursday, March 28, 2024, at the San Diego Convention Center, California, USA.
