What speed optical module does a 4G base station use
In 4G network, the optical modules used to connect BBU and RRU are mainly Gigabit to 10 Gigabit optical modules; in 5G network, the optical modules used to connect BBU and RRU are mainly 25G rate. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. 25G SFP optical module adopts the wavelength of 850nm, with an operating. As wireless data rates increase with high-speed 3G now, and move toward the future with even faster 4G services, the ability to eficiently handle the large number of bits flowing through base stations becomes critically important. Building on the 400G foundation, advancements in optical communication technologies, such as DSP (Digital Signal. The transmission carriers connecting BBU and RRU devices are optical modules and optical fibers. In 5G networks, CPRI is also upgraded to eCPRI.
