A Wavelength Division Multiplexing (WDM)-enabled analog mobile fronthaul architecture is presented supporting enhanced flexibility by exploiting the fine filtering properties of a fully reconfigurable, silicon photonics-based filtering element. Numerical studies are presented emphasizing on the flexibility, low-energy consumption, and the compatibility of our proposed chip-scale implementations with the analog Radio over Fiber (RoF)-based mobile transport. Proof-of-concept analog photonic processing of 1 Gbaud Quadrature Phase Shift Keying (QPSK)-modulated radio is successfully demonstrated through RoF transmission experiments. The integration of the analog mobile fronthauling segment in a WDM-enabled, Reconfigurable Optical Add/Drop Multiplexers (ROADM)-assisted fronthaul/midhaul infrastructure supporting low-latency edge computing is also discussed.

提出了一种支持波分复用（WDM）的模拟移动前传架构，该架构通过利用完全可重新配置的基于硅光子的滤波元件的精细滤波特性来支持增强的灵活性。提出了数值研究，强调了灵活性，低能耗以及我们拟议的芯片规模实施与基于模拟光纤无线电（RoF）的移动传输的兼容性。通过RoF传输实验成功证明了1 Gbaud正交相移键控（QPSK）调制无线电的概念验证模拟光子处理。在支持WDM的情况下将模拟移动前传部分集成在一起，
