Training a single large language model can consume more than 10 petabytes of data and generate traffic spikes that exceed 1 terabit per second per rack. Traditional copper‑based back‑plane links struggle to keep pace because resistance, skin effect, and signal‑integrity limits force designers to increase power and cooling budgets. Optical interconnects, which transmit light through fiber rather than electrons through metal, sidestep those constraints. They deliver higher per‑lane capacity, lower latency, and dramatically better energy efficiency per gigabit. Marvell Technology Group Ltd. entered the optical arena through the 2020 acquisition of Aquantia and the 2021 purchase of Inphi Corporation. Those moves gave Marvell a portfolio that span...
