Telecom operators rely on optical modules to interconnect devices within mobile communication base stations. They leverage micro- and nano-photonic technologies to generate, modulate, route, and detect optical signals. In base stations, optical chips serve the following functions: Laser. Optical modules are critical components in modern data communication, serving to convert electrical signals into optical signals and vice versa. Driven by the rapid growth of big data, blockchain, cloud computing, the Internet of Things (IoT), artificial intelligence (AI), and 5G technology, global. The transmission carriers connecting the BBU and RRU devices are optical modules and optical fibers. In 5G networks, CPRI is also upgraded to eCPRI.
