Low-Complexity 100G Burst-Mode TDMA-CPON Transmission Achieving 38 dB Link Budget

We experimentally demonstrate practical 100 Gbit/s burst-mode coherent transmission with $\gt38 \mathrm{~dB}$ link budget without optical amplification. A novel $\sim 17.1 \mathrm{~ns}$ DP-QPSK preamble guarantees DSP convergence while enabling power-efficient modulation and reduced DAC requirements.
