Thermal management plays a pivotal role in enhancing the reliability and efficiency of high-power pluggable optical modules. Read Time: 6 Min Bandwidth for chip-to-chip and chip-to-memory. Traditional air-cooling solutions can no longer meet the thermal demands of high-performance chips such as GPUs, ASICs, and optical chips. According to IDC, the global liquid-cooled data center market will exceed USD 20 billion by 2027, with a compound annual growth rate (CAGR) of 25%. 2 Liquid. Liquid cooling is a heat transfer mechanism in which the coolant (typically a dielectric fluid or water), via direct or indirect contact with a high-power component like the ASIC or the optical module, removes the heat dissipated by the component and, thereby, controls its temperature.
