Huawei Unveils 7.2Tbps Optical Module for AI Infrastructure at CIOE
During this week's China International Optoelectronic Exposition in Shenzhen, Huawei unveiled what it claims to be the first near-packaged optics module capable of 7.2 terabits per second. Man Jiangwei, the director of the company's advanced optoelectronics lab, explained that the module integrates 36 channels, each operating at 200 gigabits per second, resulting in a total bandwidth of 7.2Tbps. By utilizing light signals instead of copper wiring for data transmission between AI processors, this technology enhances speed and reduces power usage. As AI clusters grow to thousands of processors, traditional copper connections struggle with bandwidth and efficiency. Huawei's module, designed to optimize optical components' proximity to network chips, aims to minimize electrical connections and signal loss. Man shared with the South China Morning Post on Thursday that Huawei is in the product development phase and plans to begin mass production once the supply chain is established. This advancement occurs amidst a competitive landscape for next-generation AI infrastructure standards.
Key facts
