Description4There are two major elements to the MSU system; the Head End (HE) hardware and the Remote Hardware. There is one HE and multiple remotes. Each Remote consists of a single Fiber-Fed Power Amplifier chassis. The Remote chassis contains a Down Link Power Amplifier, and Up Link LNA, and a Fiber Optic Transmitter and Receiver.The Head End consists of a Fiber-Fed Power Amplifier (FFPA) chassis, a DSP Chassis, and Fiber Optic Chassis. The FFPA chassis contains an Up Link Power Amplifier, a Down Link LNA, and a Duplexer. The DSP Chassis contains one each Uplink and Down Link DSP filter cards. The Fiber Optic Chassis contains a FO Transmitter and FO Receiver for each RemoteIn the Uplink (UL) path, signals from portable radios are input to the Remote DAS. These signals are amplified in a Low Noise Amplifier (LNA) and converted to light by a Fiber Optic Transmitter in the Remote chassis, and transmitted to the Head End via fiber optic cable. In the Head End rack, the light from the fiber optic cable is converted back to RF by a Fiber Optic Receiver; the RF is filtered in the UL DSP Card and the filtered signal is input to the power amplifier module. The amplified RF is fed to the outside antenna via a duplexer.In the Downlink (DL) path, signals from user radios (Motorola radios that are FCC certified) are input to the Head End LNA. These signals are filtered in the DL DSP Card, combined with signals from a Motorobo repeater, converted to light by a HE Fiber Optic Transmitter, and transmitted to the FFPA via fiber optic cable. In the Remote chassis, the light from the fiber optic cable is converted back to RF by a Fiber Optic Receiver, and the RF is input to a power amplifier module. The amplified RF is input to a bandpass filter; the filtered RF feeds the Distributed Antenna System (DAS) in the building where the remote hardware is located. A Sample Port on the front panel of the FFPA allows the user to sample the signal without interrupting main line communications. The Sample Port is 40 dB below the main RF output port.The FFPA has a processor board that monitors overall chassis operation. The processor board controls the enable signal to the amplifier and monitors forward power, reverse power, current, fan status and heat sink temperature. Forward and reverse power are derived from directional couplers built into the amplifier modules.Heat sink temperature is derived from a thermistor mounted onto the heat sink and amplifier current from a sense resistor in series with the +28-volt power input. The fan has a built-in stopped rotor line which is input to the processor board.The processor board features optional remote monitoring capability via Ethernet. The Graphical User Interface (GUI) of the Network Management System (NMS) computer can display the status of the amplifier and provide control.
