Ensure that the input signal level of the ODU receiver does not exceed –20 dBm. The maximum receive signal level (RSL) of the ODU receiver is low. Hence, one more attenuator is needed to further reduce the reflection and protect the ODU. The RF coupler cannot necessarily guarantee the good coupling of full frequency bands. Do not power on the ODU when it has no service, to avoid RF port total reflection damaging the front components of the RF port. For example, the RF port is connected to the opposite ODU, or to the RF matcher. Before the ODU is powered on, make sure that the RF port has the service with its impedance in the required range. Follow the sequence of switching off the power first and then swapping the cable. Do not hot swap the cables connected to the IF port and the RF port of the ODU.
