Mobile base stations are equipped with optical modules
The primary optical communication devices used are optical modules and optical chips, which are essential for high-speed data transfer and network interconnection. Optical chips (Optical Chip / PIC) are the critical building blocks of base station optical communication systems. What is mobile fronthaul? Mobile Fronthaul, simply put, is the separation of functions within a base station so that some of the functions can be transferred. Which optical modules are commonly used in 4G base stations? In this blog, ETU-LINK will talk about 4G base stations and common types of optical modules. In 5G networks, the optical modules used for connecting BBU and RRU are mainly at 25G speed. In line with the standards set by 5G, base stations have been restructured into three main components: AAU (Active Antenna Unit), CU (Centralized unit) and DU (Distribute Unit), with the option to deploy CU and DU either together or separately.
