We propose a polarization-multiplexed iterative polar quantization (IPQ)-based LDPC-coded-modulation scheme suitable for beyond 400 Gb/s serial optical transmission. The component LDPC codes are designed using modified progressive edge-growth (MPEG) algorithm. The proposed scheme employs 32-IPQ-based-modulation.
