3.2 SU Figure and Configuration
The SU consists of One enclosure with a mounting bracket enabling wall attachment. The SU receives
optic signal from the DU through Fiber-Optic cable, converts into 28GHz RF signal and sends the 5G
signal through the antenna. (Downlink) It also converts the 28GHz RF signal received from the UE into
optic signal and sends to the DU through Fiber-Optic cable. (Uplink)
When cascading there is the SU_C that connects between the DU and SU_E, the figure and
configuration is the same.
