Modern base stations require high bandwidth, low latency, and high reliability. Compared to traditional copper lines, optical communication provides higher transmission rates and longer distances, making it a critical technology in base stations. With the rapid deployment of 5G networks and the development of next-generation communication technologies, base stations have become the core nodes in mobile communication networks. At the heart of every optical transceiver lie three essential components. 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. In 5G networks, CPRI is also upgraded to eCPRI.
