The ODU is the outdoor unit of the microwave system. The ODU is mainly used to convert the frequency or amplify the power of the signals.
Functions and Features
The ODU is used for the frequency conversion and amplification of signals.
The ODU implements the following functions:
♦ In the transmit direction, the ODU performs up-conversions and amplifications for the analog IF signal coming from the IDU. After the IF signal is converted into the RF signal with a specific frequency, the ODU transmits the RF signal to the antenna.
♦ In the receive direction, the ODU performs down-conversions and amplifications for the RF signal coming from the antenna. After the RF signal is converted into the analog IF signal, the ODU transmits the IF signal to the IDU.
♦ The ODU provides the control channel to receive control and management from the IDU.
♦ The ODU provides the ATPC function.
♦ The ODU provides rich alarms and performance events.
♦ The ODU supports the detection of the ODU transmit power and the received signal strength indicator (RSSI).
♦ The ODU supports the detection of the ODU temperature.
♦ The ODU supports the querying of the manufacturing information of the ODU.
♦ The ODU supports the setting of mute/unmute.
