31.2Tb/s DCI Transmission System Over 3×80km Large Aeff Fibre

We demonstrate the performance of a 240km multi-span transmission system based on a new type of larger effective area(Aeff) fiber. Achieving a single-wavelength transmission rate of 1.2 Tbit/s and an aggregate capacity of 31.2 Tbit/s within the C-band, this system is designed for data center interconnect applications. The research results indicate that the new type of optical fiber offers superior performance in terms of transmission efficiency and reduced nonlinearity, thereby more effectively addressing the demands for long-haul transmission and high-bandwidth services.
