Moreover, real-time applications will benefit from single-fiber transmissions to maintain consistent media for both downstream and upstream. In SEASON, we investigate the applications of a Nokia coherent transceiver that uses digital subcarrier multiplexing (DSCM) to next generation mobile transport. This approach allows for efficient transmission via a single laser and wavelength over single fiber, satisfying next-generation mobile transport demands economically and performance-wise. DSCM transceivers also allow the interleaving of the subcarriers on frequency domain, which mitigates the impact of fiber and component reflections. Within SEASON, we developed optimization techniques for ideal transmission in both overlapping and distinct configurations within a point-to-multipoint framework, taking into account distance and power considerations. Power optimization of the subcarriers (also as a function of traffic and distance) helps to reduce the penalty induced by the reflections. The initial experimental results have been submitted to ECOC 2025. The subsequent phase involves integrating the complete study with a control plane to assess performance in case of time-varying traffic. Preliminary techno-economic analysis indicates significant OPEX and CAPEX benefits when DSCM is used instead of traditional transceivers. Data rates of at least 200 Gb\/s in both directions have been achieved, together with demonstrated CAPEX savings that exceed 40%, improving network scalability and flexibility by facilitating the addition of more leaf nodes, thus reducing OPEX. This solution facilitates next-generation 6G mobile transport, supporting applications such as dynamic traffic allocation, high-speed capacity access, and expanded macrocell diameters","references":"\"\u201c P.
