Optical modules, as core components of optical communication systems, are essentially "signal translators" connecting the digital world. At the transmitting end, they convert electrical signals into optical signals for transmission via optical fiber, and at the receiving end, they are converted back into electrical signals, enabling seamless data interaction between devices. From speeds leaping fr...
