Product Name: Tetra 400MHz Fiber Optic Repeater Model NO.: BT-7C00A/BT-7B40A Condition: New Certification: ISO, CE Lightning Protection: Lightning Arrester Standard: Standard Transmission Medium: Optical Fiber Type: Wireless Repeater Trademark: BOOSTEL Transport Package: Wooden Case Specification: 560*450*270mm Origin: China Product Description Specifications of TETRA Fiber Optic RepeaterModel: BT-7C00A/BT-7B40AThe Fiber Optic Repeater (FOR) is designed to solve problems of weak mobile signal in the place that is faraway from the base Transceiver Station (BTS) and has fiber optic cable network underground. The system consists of two parts: Donor Unit and Remote Unit. The Donor unit captures the BTS signal via direct coupler closed to BTS, then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cable. The Remote unit will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.Features Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrodingOmni-directional antenna can be adopted to expand more coverageTx/Rx control and alarm messages can be transmitted via one fiber optic cableAdopting WDM module to realize long-distance transmissionStable and improved signal transmission qualityOne Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cableUSB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeaterApplicationsTo expand signal coverage or fill signal blind area where signal is weak or unavailable.Outdoor:Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …Indoor:Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …Application DiagramTechnical Specifications ItemSpecificationsWorking Frequency(DL Selective)UplinkTETRA400 MHzDownlinkTETRA400 MHzMaximum Input Power 10 dBmTransmission Distance≤ 20kmMaximum Output Power(Customized)43dBmMaximum Gain(Cable access)≥ 60dBGain Adjustment Range1~31 dB @ step of 1 dBVoltage Standing Wave Ratio< 1.5Noise Figure≤ 5dB(only for uplink)In-band Ripple≤ 3dBSpurious EmissionWithin working band≤ -15dBm/30kHzOut of working band(f > 2.5MHz)9kHz~1GHz: ≤ -36dBm/30kHz1GHz~12.75GHz: ≤ -30dBm/30kHzThird-order Inter-Modulation≤ -45dBc / 30kHz (measured under rated output power)System Delay≤ 5μSecI/O Impedance50ΩRF ConnectorN-Type (Female) / Changeable / bottom of casingFiber Optic Light SourceLaser unit (wavelength:1310nm/1550nm)Optical Output Power≥0dBm(1310nm) / ≥3dBm(1550nm)Optical Receiver Sensitivity≤-25dBmTemperature RangeOperation: -25°C ~ + 55°C / Storage: -30°C ~ +60°CRelative Humidity Range≤ 95% (non condensing)Power Supply (customized)DC-48V or AC110V or AC220V,50/60HzPower consumption≤ 15W(Donor Unit)≤ 150W(Remote Unit)Backup Power Supply (optional)4 hoursCasing LevelIP32IP65Dimensions418mm X 90mm X 290mm428mm X 328mm X 220mmWeight6kg35kgNMS Monitoring Function (optional)Real-time alarm for door status, temperature, power supply, LNA, VSWR, self-oscillation, etc;Remote control turn on/off, increasing/decreasing output power, etc;Real-time status for output/input power, UL/DL gain, all status of repeater's.Installation & Commissioning1.1 Installation1.1.1 Steps for mounting on the 19" Standard CabinetMaster UnitFind a place with 2U height inside the 19" standard cabinet near the BTS.Insert the FOR Donor Unit into the cabinet.Fasten the Donor Unit onto the cabinet via four screws.Connect two couplers to the BTS terminals of the selected sector (the sector antenna shall be facing against the area to be covered) as shown in Figure 4-4. Connect a RF Combiner between the coupler and Donor Unit with 3 RF Jumper Cables (see Figure 4-3) as shown in Figure 4-4. Each of the RF Jumper Cables has N-Male connectors at two ends.Connect one optic patch cord (see Figure 4-6) between the fiber optic terminal and the Donor Unit. And cover the other patch cords with a plastic bag for protection.Connect the power cable between the BTS -48V power supply and the Donor Unit.Remote Unit1.2.1 Steps for mounting on the PoleAt Donor site, install the FSR Donor Unit, Donor Antenna, link Antenna, and RF cable as per specified plan and site layout. FSR Donor Unit can be pole-mounted using the brackets as shown below.Place M8 screws through the holes of H type brackets as shown in figure 1Fix combiner onto the H type brackets with M6 screwsFix H type brackets with combiner installed onto the pole with U type brackets and M8 screwsFigure 1 Repeater Mounting BracketOrient the link Antenna of Donor Site to the direction of the Remote Site.Use Site Master to measure the VSWR of the RF cable from the link Antenna. The value should be less than 1.5; Otherwise, check the connectors and the installation of the cable.Start Commissioning the Donor Unit .Proceed to the Remote Site.At Remote site, install the FSR Remote Unit, link Antenna, Coverage Antenna, and RF cables. Remote Unit can be wall mounted or pole mounted depending on the approved plan.Orient the Remote link Antenna to the direction of the Donor Site.Using Spectrum Analyzer, check the link RSL; adjust the link Antennas of both Donor and Remote until the required RSL is achieved. link RSL can be computed using conventional path calculation method.Then, measure the VSWR of the RF cables connecting with the link Antenna of Remote Unit. The value should be less than 1.5, otherwise, check the connectors and the installation of the cable.Start Commissioning the Remote Unit .1.1.2 Steps for mounting on the wallAt Donor site, install the FSR Donor Unit, Donor Antenna, link Antenna, and RF cable as per specified plan and site layout. FSR Donor Unit can be wall-mounted using the brackets as shown below.Make four marks on the wall according to the dimension shown as figure 2Drill four holes at position markedFix two pcs H type brackets on the wall with M8 expansion screwsFix combiner onto the brackets with M6 screwsFigure 2 Repeater Mounting Bracket 6. The following steps are the same with step 4 to 12 for mounting on the Pole.1.3 CommissioningConnect the RF cable from Donor Antenna to the spectrum analyzer and check if the Donor Antenna is receiving the correct frequency; and then measure the signal level of the said frequency (RSL). Adjust the antenna to make the readings approach the recorded value on the survey report. Record all readings.Inside the repeater, disconnect the uplink duplexer to the ICS module so as to cut any signal coming from air going to the uplink duplexer and thus protecting the amplifier from damaging. Connect a 30 dB attenuator to the output of the repeater; this attenuator will serve as a load for the repeater. The purpose of this attenuator is to protect the equipments from damaging.Turn ON the repeater. Observe the LED display on the NMS board. Check for any alarm. Under normal condition, the POWER LED should be always green and the RUN LED should be blinking, the ALARM LED should be not bright with red color.Connect your laptop to the repeater via the data cable.
