Optical interconnects are advanced communication systems that use light to transmit data between different components in computers and networks. Unlike traditional electrical connections, which rely on copper wires, optical interconnects utilize fiber optics to send information as pulses of light. This method allows for faster data transfer rates and reduced energy consumption, making it ideal for high-performance computing and data centers. These interconnects are becoming increasingly important as the demand for faster and more efficient data transmission grows. By leveraging lasers and photodetectors, optical interconnects can connect various devices over long distances without losing signal quality. This technology is paving the way for the future of communication in the digital age.
