  • What is the difference between 100G, 400G and 800G optical modules?

    In optical communication systems, optical fiber serves as the transmission medium, transmitting signals in the form of light. However, the analysis and processing of information require signals to be in an electrical state. Optical modules are one of the core components of optical fiber communication systems, primarily responsible for optical-electrical conversion. Optical modules include optical
