显著提升测试可靠性与一致性 湖北省计量院一创新技术每年减少碳排放7500吨

Core Viewpoint - The Hubei Provincial Institute of Metrology and Testing Technology has developed innovative testing technology for 800G ultra-high-speed optical modules, addressing electromagnetic compatibility (EMC) testing challenges and contributing to the advancement of the optical communication industry in Wuhan's "Optical Valley" [1][2]. Group 1: Technological Innovations - The institute has created a method for EMC radiation emission testing of 800G optical modules, overcoming the lack of international standards and high-frequency testing technology above 40GHz [1][2]. - A detachable standardized testing tool has been designed, compatible with mainstream packaging, ensuring uniform testing conditions across different enterprises [2]. - The technology employs a harmonic mixer down-conversion technique to convert signals above 40GHz into measurable ranges, facilitating the transition from "following standards" to "defining standards" in EMC testing [2]. Group 2: Industry Impact - The developed technology has provided over 50 high-frequency EMC testing services to optical communication and device companies in Hubei, reducing the testing cycle from 15 days to 10 days, resulting in a 33% efficiency improvement and saving over 20 million yuan in R&D costs [3]. - The optimization of optical module EMC performance has contributed to the green development of computing networks, with the energy efficiency ratio (PUE) improving from 1.4 to 1.25, leading to an annual electricity saving of over 12 million kWh and a reduction of 7,500 tons of carbon emissions [3].
