N2 - In this invited paper, we describe our recently proposed software-defined networking (SDN)-enabled, adaptive resource allocation framework, including hybrid signalling schemes, for mobile fronthaul (MFH) networks that employ both coherent detection (CD) and direct detection (DD) technologies. To optimize application performance and network efficiency, we propose phase-coded three-level pulse amplitude modulation (PAM-3) for multicast traffic delivery to CD and DD nodes. We implement several connectivity scenarios based on both typical and improved PAM-3 in an SDN fronthaul testbed and examine the pre-forward error correction (FEC) bit error rate (BER) performance for 25 Gbaud signals. Using low-density parity-check (LDPC) codes to achieve the desired post-FEC BER levels, we study the performance gains due to code rate adaptation in dynamic wavelength-routing MFH networks.
