Support. In intelligent computing centers built around large-scale GPU clusters, network bandwidth, latency, and reliability directly determine the efficiency of AI training, big data processing, and other tasks. As a core component connecting servers, switches, and storage systems, optical modules play a. Optical modules help edge computing move data very fast. These modules use fiber optic technology for quick and steady communication between edge nodes. This makes the distance and number of network hops. Its core concept is to remove digital processing units such as DSPs and CDRs from the module, constructing a purely analog "linear direct-drive" optical link. They convert electrical signals to light, correct distortion in real time, and ensure reliable, low-latency transmission from tens of meters to thousands of kilometers.
