Amplitec O37T series digital fiber optical repeater adopts software radio technology. The main unit performs frequency conversion processing after receiving downlink signal from the donor antenna, and converts it into an I/Q signal, which is converted into a digital signal by ADC and then sent to the remote unit through optical fiber. the remote unit recovers the received digital signal and converts it into an analog signal through the DAC, then converts the frequency to the radio frequency, and transmits it through the service antenna; the remote unit sends the received uplink signal of the mobile phone to the base station through the above reverse process.
The O37T MU (main unit) has 4 FC optical ports, which can be connected to 4 RU(remote unit). The RU is also equipped with 2 LC optical ports, which supports parallel or series connection of multiple RU. The transmission distance between the MU and the RU is up to 15km, which is suitable for 2G 3G 4G 5g signal coverage in villages, tunnels, mines and other places.
