Fiber Distributed Antenna System (Fiber DAS) Operation Manual ©Copyright 2019 by Bird Technologies, Inc. Instruction Book Part Number 920-Fiber-DAS Rev. P5 Delta Node® is a registered trademark of Delta Node Solutions Ltd. and Bird Technologies, Inc. i Safety Precautions The following are general safety precautions that are not necessarily related to any specific part or procedure, and do not necessarily appear elsewhere in this publication. These precautions must be thoroughly understood and apply to all phases of operation and maintenance. WARNING Keep Away From Live Circuits Operating Personnel must at all times observe general safety precautions. Do not replace components or make adjustments to the inside of the test equipment with the high voltage supply turned on. To avoid casualties, always remove power. WARNING Shock Hazar d Do not attempt to remove the RF transmission line while RF power is present. WARNING Do Not Service Or Adjus t Alone Under no circumstances should any person reach into an enclosure for the purpose of service or adjustment of equipment except in the presence of someone who is capable of rendering aid. WARNING Safety Earth Ground An uninterruptible earth safety ground must be supplied from the main power source to test instruments. Grounding one conductor of a two conductor power cable is not sufficient protection. Serious injury or death can occur if this grounding is not properly supplied. WARNING Resuscitation Personnel working with or near high voltages should be familiar with modern methods of resuscitation. WARNING Remove Power Observe general safety precautions. Do not open the instrument with the power applied. Safety Precautions ii Safety Symbols WARNING Warning notes call attention to a procedure, which if not correctly performed, could result in personal injury. CAUTION Caution notes call attention to a procedure, which if not correctly performed, c ould result in damage to the instrument. Note: Calls attention to supplemental information. The laser used in this system is a Class 3b laser that produces invisible infra-red coherent light. Avoid looking into connected fibers and receptacles. Not safe to view with optical instruments. Always put the protection caps on unused fibers and receptacles. Fiber Distributed Antenna System (Fiber DAS) iii Warning Statements The following safety warnings appear in the text where there is danger to operating and maintenance personnel and are repeated here for emphasis. WARNING This is NOT a consumer device. It is design for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC licensee to operate this device. You MUST register Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each c ontinuing violation. See page 43 For CMRS 817-824MHz Applications and American Cellular Applications: WARNING This is NOT a consumer device. It is design for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC licensee to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. See page 43 WARNING This is NOT a consumer device. It is designed for installation by an installer approved by an ISED licensee. You MUST have an ISED LICENCE or the express consent of an ISED licensee to operate this device. WARNING Avoid looking into connected fibers and receptacles. The laser used in this system is a Class 3b laser that produces invisible infra-red coherent light. Not safe to view with optical instruments. Always put the protection caps on unused fibers and receptacles. See page 43 See page 15 Safety Precautions iv Caution Statements The following equipment cautions appear in the text and are repeated here for emphasis. CAUTION Turn Off Test Tone Do not forget to turn off the test tone when you are done with your uplink. Better check one extra time. They will otherwise interfere with the normal operation of the system by causing noise to the base station. See page 118 CAUTION Unauthorized antennas, cables, and/or coupling devices may cause non-conformity with national or international regulations, could cause damage, or non-conforming ERP/EIRP. See page 44. CAUTION When mating RF connectors, ensure that they are properly aligned and not cross threaded. Tighten SMA connectors to 8 in.-lbs. Do over torque RF connectors, this could result in damage to the Unit. Do not under torque RF connectors, this could result in poor signal transmission.

Remote unit has a built in ALC (Automatic Level Control) with preset levels, to make sure that the linearity or spectral spreading does not exceed the regulatory limits. All Bird remote units and repeaters have the ALC feature and functionality. The ALC threshold is a settable value that defines what output power is allowed from the RU/repeater. If an inserted signal plus the set gain in the RU/repeater exceeds the set ALC threshold the RU/repeater will automatically reduce the gain so that the output signal level always matches the set ALC threshold. The device cannot end up in saturation due to the ALC (Automatic Level Control) feature/functionality. Saturation or over-modulation is even prevented for pulsed signal inputs with above described functionality. There are also configurable signal threshold parameters in the remaining components of the DAS system [Base station Interface (BIU), Fiber Optical Interface (FOI), that are used for proper commissioning of the system so that these types of abnormalities (overpowered input signals) are eliminated. UL Test Tone is a help feature tool used only when commissioning the DAS network. DL ALC threshold for all DDR family Remote units is 33 dBm +/-1dB.
