>>Introduction
    WCDMA2100MHz 3G FIber Optical Repeater is the equipment for the network optimization in the mobile network that can enlarge the BTS coverage. It is widely used in the shaded area, high traffic load area and the pilot pollution area, etc.
 
>>Working Principle
The Downlink,master unit of TX/RX receives the downlink(DL)signal from BTS through the couple,is amplified by DL Amplifier and Input Power Detection.
    The RF signal converts to IF signal by using a mixer. IF signal transform into digital signal by digital module, which has included technologies of D/A conversion、digital down-conversion and digital filtering.  The digital optical signal is transmitted via master optic unit and fiber to the remote unit,in which digital optic signal is converted back to (Digital filtering 、digital Up-conversion and A/D conversion)RF signal via remote unit . RF signal is amplified in the DL AMP(Amplifier) and PA(Power Amplifier) to meet a required output power level,and then to remote DL filter, and transmit at port of “To Service (TX) port.”
    The uplink RF signal of mobile terminal in the coverage area is inputted by the port of the “To Service (TX)”, which is filtered by duplexer and amplified by the ULNA (Uplink Low Noise Amplifier).
Same as DL, using mixer to convert UL RF signal to IF signal, which convert to digital optical signal by using technologies of D/A conversion、digital down-conversion and digital filtering. The digital optical signal have been transmitted via master optic unit and fiber to remote unit, in which optic signal converted back to RF(Digital filtering 、digital Up-conversion and A/D conversion)signal then being amplified 、flittered by the UL AMP(Amplifier)and duplexer, after all processing, the signal are going to be transmitted at port of“ RX Port.”
    The main controlling panel (PCM) of master unit and remote unit will control their modules and communicate with each other via the data link of the optic modules. User can inquire and set the parameters by LOC (local monitoring) interface on the master/remote unit. and user also can do in the OMC(Operation and Maintenance Center) by IP network.
    Power supply unit, which supplies power to all the active modules and in charge of charging battery.
