DO NOT look directly into the fiber optic connectors when unit is in operation. Connect RF Output to existing Distributed Antenna System (DAS) cable only. DO NOT operate equipment with unauthorized antennas, cables, and/or coupling devices. DO NOT operate equipment unless all RF connectors are secure. DO NOT operate equipment unless it has been installed and inspected by a qualified radio technician. Description There 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 (FFPA) chassis. In the Downlink (DL) path, signals from user radios (Motorola radios that are FCC certified) are input to the DL HE hardware. These signals are filtered, converted to light by a Fiber Optic Transmitter, combined with signals from a Motorobo repeater, and transmitted to the FFPA via fiber optic cable. In the FFPA 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. In the Uplink (UL) path, signals from portable radios are input the DAS. These signals are amplified in a Low Noise Amplifier (LNA) in the FFPA, converted to light by a Fiber Optic Transmitter, 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, and the RF is input to a power amplifier module. The amplified RF is fed to the outside antenna via a duplexer. A front panel Look Port on the front panel of the FFPA allows the user to sample the signal without interrupting main line communications. The Look Port sample 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. 68 WHITE STREET #265 RED BANK, NJ 732-889-4671 AMDI Provided Data To DA BPF-A CCCF-173 PA HD Comm HD30433 AMDi 1473PA-X-X A1 DL- 460.3625 461.5875 461.9625 478.2500 From UH FOR MSU LFD Revisions DATE From DAS Mini-Ckts LNA ZFL-500LN+ AMDi 1473PA-X-X A3 UL- 465.3625 466.5875 466.9625 481.250 DRAWN BY REVISION NOTE APPRVD.

The fiber optic laser is applied to “ A “ shown below. The 1550 nm laser light is converted to radio frequency (RF) signal at “ B.” At “ C “ is the amplified and filtered RF signal from “ B. “ The amplifier has an Automatic Level Control (ALC) feature. This feature limits the power amplifier output in case the input to the amplifier exceeds the required level. The power amplifier ALC level is set to +20 dBm.
