Abstract

In the last 15 years, global data traffic has been doubling approximately every 2–3 years, and there is a strong indication that this pattern will persist. Hence, also driven by the emergence of new applications and services expected within the 6G era, new transmission systems and technologies should be investigated to enhance network capacity and achieve increased bandwidth, improved spectral efficiency, and greater flexibility to effectively accommodate all the expected data traffic. In this paper, an innovative transmission solution based on multiband (MB) over spatial division multiplexing (SDM) sliceable bandwidth/bitrate variable transceiver (S-BVT) is implemented and assessed in relation to the provision of sustainable capacity scaling. MB transmission (S+C+L) over 25.4 km of 19-cores multicore fibre (MCF) is experimentally assessed and demonstrated achieving an aggregated capacity of 119.1 Gb/s at 4.62×10−3 bit error rate (BER). The proposed modular sliceable transceiver architecture arises as a suitable option towards achieving 500 Tb/s per fibre transmission, by further enabling more slices covering all the available S+C+L spectra and the 19 cores of the MCF.

面向未来光网络的多频带空间分复用可分片收发器

在过去 15 年中，全球数据流量大约每 2-3 年翻一番，而且有强烈迹象表明这种模式将持续下去。因此，在 6G 时代新应用和新服务不断涌现的推动下，应研究新的传输系统和技术，以增强网络容量，提高带宽、频谱效率和灵活性，从而有效地适应所有预期的数据流量。本文实施了一种基于空间分复用（SDM）多频段（MB）可切带宽/比特率可变收发器（S-BVT）的创新传输解决方案，并就提供可持续容量扩展进行了评估。通过实验评估和演示，在 25.4 公里长的 19 芯多核光纤（MCF）上进行了 MB 传输（S+C+L），在 4.62×10-3 误码率（BER）条件下实现了 119.1 Gb/s 的总容量。提议的模块化可切片收发器架构是实现每条光纤 500 Tb/s 传输的合适选择，可进一步实现覆盖所有可用 S+C+L 光谱和 19 芯 MCF 的更多切片。
