The main role of 400G optical modules is to provide high-speed, large-capacity data transmission to meet the needs of modern data centers and communication networks for high-performance computing and big data processing. 400G optical modules convert electrical signals into optical signals for transmission through photoelectric conversion, then transmit the optical signals to the receiving end through optical fibers, and finally restore the optical signals to electrical signals, thereby achieving high-speed, low-latency data communication.
