Low-power O-band receivers are required for next-generation coherent intra-datacenter interconnects. In this paper, a 0.98 pJ/bit QPSK receiver using a 45 nm CMOS process and a 90 nm Silicon Photonics (SiP) process is demonstrated at up to 50 GBaud.

Using real-time transceivers with symbol rates up to 72 GBd, we investigate the impact of ROADM filtering on optimum symbol rate and fractional m-QAM modulation required to maximize channel capacity. Granularity below 5 GBd is shown to yield maximum margin for a given link passband.

Theoretical gains of digital multi-carrier systems are hindered by the use of sub-optimal conventional phase recovery, especially after fiber transmission. We experimentally validate an advanced, dispersion-aware algorithm that addresses this issue, achieving SNR gains up to ∼0.5 dB with 800G 125 Gbaud 16-carrier PCS-64QAM, transmitted over 1800 km.

For 200Gbit/s net rates, uniform PAM-4, 6 and 8 are experimentally compared against probabilistic shaped PAM-8 cap and cup variants. In back-to-back and 20km measurements, cap shaped 80GBd PAM-8 outperforms 72GBd PAM-8 and 83GBd PAM-6 by up to 5.17dB and 2.17dB in receiver sensitivity, respectively.

We estimate resource savings from low-margin optical-network design considering (i) different transmission modes (including PCS), (ii) full vs. actual load for interference modelling and (iii) greedy heuristic vs. evolutionary metaheuristic for routing. Numerical results, mimicking multi-year-traffic evolution, allow to quantify extent of these savings.

We demonstrate the successful operation of an FPGA-based A-IFoF/mmWave transceiver into an existing MNO infrastructure, delivering 4K video streaming and IP-calls over mobile core network. Physical layer connectivity was successfully established, with EVM measurements of <10% for QPSK waveforms propagated through different optical-wireless network segments.
