Digital source meters (SMUs) are core instruments for testing semiconductors, optoelectronics, and new materials. They integrate precision voltage/current output and measurement functions, and the rationality of their selection and the standardization of their operation directly determine the testing accuracy and equipment lifespan.

In scenarios such as optical communication operation and maintenance, data center testing, and optical device research and development, multi-channel synchronous testing has long been a necessity. However, relying solely on multi-channel optical power meters is insufficient when dealing with multiple fiber optic connections switching in turn and batch monitoring at multiple locations.

Driven by the explosive growth of AI computing power, the evolution of 5G-A/6G, and the "East-to-West Data Transfer" project, optical modules are rapidly iterating towards higher speeds, higher integration, and lower power consumption, with 800G becoming the current market mainstream.
