Abstract: In this paper, we propose an integer linear programming model to dynamically optimize sub-carrier (SC) allocation in the upstream direction of future digital sub-carrier multiplexing (DSCM)-based coherent passive optical networks (PONs). The model incorporates frequency-domain hybrid modulation to account for the varying conditions of optical network units, optimizing resource allocation while minimizing the number of SCs used. Numerical results demonstrate that hybrid modulation increases PON throughput by about 50 Gbps for 32 optical network units.
