Remarks
The RFU performs modulation and
demodulation between baseband signals and
RF signals, processes data, and combines and
divides signals.
To ensure proper ventilation of the cabinet, the
slot in the RFU subrack that is not installed
with an RFU must be installed with a filler
panel.
The fan dissipates the heat in the cabinet.
The BBU3900 processes the baseband signals
and enables interaction between the base
station and the base station controller.
The DCDU-01 provides DC power to all
components in the cabinet.
The power equipment (DC/DC) converts
external +24 V DC power into -48 V DC power
and provides power to all components in the
cabinet.
The power equipment (AC/DC) converts
external 220 V AC single-phase, 220 V AC
three-phase, and 110 V AC dual-live-wire
power into -48 V DC power and provides
power to all components in the cabinet.
