Description

technical field [0001] The invention relates to a parallel optical transceiver component for broadband high-speed transmission. Background technique [0002] With the rapid growth of human's demand for communication bandwidth, existing communication systems are facing two challenges of capacity and energy consumption. Due to the ability to provide greater bandwidth in a smaller space and lower power consumption, the research and development of parallel optical modules is increasing. Parallel optical modules are multiple lasers aligned with multiple fibers in a single module - such as a 4-channel short-range transceiver module suitable for short-range high-bandwidth computing and switching applications, integrating four independent transmit and receive channels, and connected to A 12-channel multimode ribbon fiber. Due to the high bandwidth density and low power consumption brought about by device integration and miniaturization, the transmission bandwidth and power consump...
