Telecom operators rely on optical modules to interconnect devices within mobile communication base stations. Driven by the rapid growth of big data, blockchain, cloud computing, the Internet of Things (IoT), artificial intelligence (AI), and 5G technology, global. Optical modules used in Remote Radio Units (RRUs) for CPRI applications are required to support industrial temperature ranges, primarily because RRUs operate in diverse outdoor environments with extreme temperature variations. CPRI (Common Public Radio Interface) defines the interface relationship. RRU (Remote Radio Unit): interface with Antenna in one side and with BBU in the another side. Converts the RF signal into data signal and the vice versa. Filtering and amplification of RF signal. All devices need to be connected to a fiber network that provides the data nits, the RRU, and Baseband Units, the BBU.
