  • Which optical modules are commonly used in 4G base stations?
    Which optical modules are commonly used in 4G base stations?
    • March 15. 2022

    In this blog, ETU-LINK will talk about 4G base stations and common types of optical modules. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. The BBU is small and exquisite, with low power consumption, while the RRU is large and has high power consumption. Because the base station is divided into two parts to work sepa...
