In recent years, driven by the rapidly growing demand for AI data centers, technology giants such as NVIDIA, Google, and Amazon have accelerated the deployment of large-scale AI compute clusters. This surge has ushered in a new wave of growth and innovation for the optical communications industry.With high-speed SERDES technology advancing to 1.6T, AI and machine learning workloads now demand even greater system reliability. Any performance shortfall in optical modules can disrupt AI training tasks and lead to costly downtime. To prevent this, equipment vendors and optical module manufacturers must perform rigorous BER testing on computing interfaces to ensure they meet the stringent reliability standards required for AI computing.
Nexustest is dedicated to advancing the core technologies behind high-end optoelectronic test instruments. Building on our deep expertise in high-speed signal processing and integrity analysis, we have introduced a new generation of high-speed BERT solutions. As the first supplier in China to launch and sample a 1.6T BERT solution, Nexustest offers a comprehensive system platform designed for next-generation high-speed optical module testing applications.
