2.5 Radio Signal and Data Communication Paths
In the downlink the radio signal is tapped from a BTS using a coupler installed in series with the BTS’s antenna
cable. The Fibre Optic Converter in the OMU converts the RF signal to an optical signal and sends it to the
repeater over a fibre.
In the uplink the Fibre Optic Converter receives the optical RF signal from the repeater, converts it to electrical
RF signal and sends it to the BTS. The signal is transferred to the antenna cable using a coupler.
The Control Module in the OMU monitors all units in the OMU.
The Control Module also monitors and controls the repeaters (if they are set up as slaves). The data
communication with the repeaters is handled over the same fibre as the RF signals.
