What are the upstream components of an optical module

They mainly consist of optoelectronic components (such as optical transmitters and receivers), functional circuits, and optical interfaces, aiming to achieve the functionalities of optical-to-electrical and electrical-to-optical signal conversion in optical fiber communication. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. The most common optical transceiver components include TOSA, ROSA, BOSA, laser diodes, and photodiodes. Each component has its own specific function. TOSA converts electrical signals into light. In the era of 5G, AI, ...
