Chapter 1 Introduction The Bird fiber distributed antenna system (Fiber‐DAS) was developed from the start with fiber‐optic cable as the distribution medium. This allows for excellent radio performance and best in class system noise figure of less than 3 dB, from the remote unit antenna port to the base station interface port. The Bird Fiber‐DAS system is a flexible and scalable solution, meaning the system can be tailored for almost any requirement.
Introduction Definitions The following abbreviations, industry standard lingo and acronyms are used in this document. BGW BIU BTS DAS DL Downlink Fiber Fiber‐DAS FOI FOR GSM iDEN LTE MFU ICU QMA RBS RGW RU SC‐APC Single mode fiber SMA Switch Base station Gateway, see "Base Station Gateway (BGW)" on page 4 Base station interface. Also known as the DIU.
Fiber Distributed Antenna System (Fiber DAS) TETRA UL UMTS Uplink SC‐PC SC‐UPC RF WCDMA W‐CDMA 3 Terrestrial Trunked Radio. TETRA uses Time Division Multiple Access (TDMA) with four user channels on one radio carrier and 25 kHz spacing between carriers. See “Uplink” Universal Mobile Telecommunications System is a system where broadband signaling and packeted data are used. The standards are handled in the 3GPP group and the most common type of modulation is WCDMA.
Chapter 2 System Description The Fiber‐DAS system typically consists of three main segments: Gateway — The Gateway acts as a firewall ensuring internal traffic on the system remains internal and at the same time allowing a web interface for monitoring and supervision. The gateway also handles SNMP traps.
Fiber Distributed Antenna System (Fiber DAS) Northbound communication to CGW Includes firewall to protect local net Portal to your Master Unit User‐provided certificate based security via HTTPS Figure 2 Base Station Gateway The BGW has two Ethernet ports ‐ INT and EXT. The INT port is connected to the internal network in the headend’s Master Unit to provide the local network for all the modules and the Remote Units.
System Description Remote Gateway (RGW) The RGW is a small unit similar to the BGW but intended for small systems where there are only a few remotes or where there is no headend. The RGW has a form factor that allows it to be mounted inside a repeater casing. The RGW can be used to run up to 4 Remote Units from a single Repeater on a single Fiber. The RGW has the capability to connect northbound to a CGW, just like the BGW, and it can also forward alarms through a VPN tunnel to a CGW.
Fiber Distributed Antenna System (Fiber DAS) Master Frame Unit (MFU) The Master Frame Unit (MFU) houses the Power Supplies, Base Station Interface Units (BIU), Interconnection Units (ICU), and Fiber‐Optic Interface (FOI) cards. Figure 3 shows an MFU equipped with 3 BIUs, 6 FOIs and one Power Supply. Figure 3 Master Frame Unit Functional description One MFU supports several modules, or combination of module types. The modules can be placed anywhere in the frame.
System Description Base Station Interface Unit (BIU) The Base Station Interface Unit (BIU) is the interface between the operator’s base station and the Fiber‐DAS system. The primary purpose of the BIU is to adjust uplink and downlink signal levels.The BIU is powered from the MFU backplane and communicates via Ethernet with the BGW.
Fiber Distributed Antenna System (Fiber DAS) The BIU has four QMA ports (female type) that are normally used to connect it to an ICU. There are two uplink (input) ports and two downlink (output, TX) ports. These are two separate paths, the isolation between DL 1 and DL 2 ports and the isolation between the UL 1 and UL 2 ports is > 50 dB. There are two separate RF paths in the BIU. The BIU is configured for the specific frequency band it will serve.
System Description The schematic in Figure 6 shows one of the channels in the BIU. The signal detector for the downlink level alarms is shown in the top right corner. The UL1 and UL2 uplink test ports are 3 dB lower than the signal on the corresponding DL/UL BTS port. Figure 6 Schematic of One BIU RF Path Table 4 lists standard cellular BIU’s.

Test port for the uplink of the DL/UL BTS port ‐ 6 dB. The signal will be 3dBm below the DL/UL BTS port.
Fiber Distributed Antenna System (Fiber DAS) Interconnect Unit (ICU) Interconnect units (ICU) are used to couple signals between the BIUs and the FOIs. The functional purpose of the ICU is: Downlink ‐ Split the signal from the BIU and route the balanced signals (minus insertion loss) to the FOIs. Uplink ‐ Combine the signals from the FOIs and route the sum of the signals (minus insertion loss) to the BIU. The RF ports on the ICU are QMA.
System Description Rack-mount ICU (DIU301, DIU302) The Rack‐mount ICU is a 1U unit that contains four fields containing splitters/combiners. Each field is capable of splitting one input into eight outputs or combining eight inputs into one output. Figure 10 Rack-mount ICU Each of the 4 fields has a COMMON port and ports 1‐8.
Fiber Distributed Antenna System (Fiber DAS) Fiber Optic Interface (FOI) unit The FOI converts the RF signals in the downlink to fiber‐optical laser output that is transmitted on the fiber to the remote unit. It also receives the laser light transmitted by the Remote Unit and converts it back to RF signals that are then routed to the ICU and/or BIU.
System Description DOI300 Series FOI The DOI300 series supports a single fiber optic link. The fiber‐optic interface can either be a WDM (DOI302) which is most commonly used or an optional duplex feed with separate UL and DL fibers (DOI301). Bird also offers a WDM option (DOI380x). The WDM utilizes the duplex feed style card but the wavelength for the downlink are defined by the "x" in the DOI380x part number. Note that the Remote Unit will need to be ordered with the correct WDM uplink wavelength.

DOI302 module with built in WDM has a single connector (combined RX/TX). DOI301 module without WDM has two connectors, one for TX and one for RX.
Fiber Distributed Antenna System (Fiber DAS) DOI401Series FOI The DOI401 four port FOI is very similar to DOI302 expect that it has four WDM optical ports instead of one. This allows the user to install dedicated fibers to each Remote Unit without having to balance optical splitter link budgets for each remote in a group. The balanced splitter loss is accounted for in the 7 dBo link budget of the DOI401. Unlike the DOI302, the DOI401 does not require the UL optical signals to be on different wavelengths.
System Description PSU – the rack power supply The Power Supply Unit provides DC power to the Master Unit backplane. The unit is shipped as 240 VAC or 115 VAC units depending on the country. A ‐48 VDC input is offered as an option. Figure 18 PSU DC Power Supply AC Power Supply Functional description The AC power supply can handle up to 16 cards or one chassis full of cards. The DC power supply is capable of handling 11 cards or one full chassis that includes the DC power supply.

Chapter 3 Installation guidelines WARNING This is NOT a consumer device. It is designed 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 continuing violation.
Fiber Distributed Antenna System (Fiber DAS) Cable Routing/Antenna Selection Ensure all cables, e.g. power cable, fiber‐optic cable, Antenna cables are routed and secured in accordance with local/national requirements while avoiding damage to the cables. Antennas and coax cables are selected as part of the DAS system design and may vary with location, frequency, and power level requirements. Use only authorized and approved antennas, cables and/or coupling devices.
Installation guidelines Tools and Material Requirements Fiber Optics All fiber optic cables, including patch cords, must be SINGLE MODE. Multi‐mode fiber is not supported. Bird equipment is designed to be used with only SC/APC fiber connectors. All connection points in the fiber must either be fusion spliced or equipped with APC connectors. UPC connectors anywhere in the fiber path will cause degradation in the performance of the equipment. APC connectors can be identified by their green jacket.
Fiber Distributed Antenna System (Fiber DAS) Installing Headend Equipment All equipment must be properly grounded. Ground peg in the main connector for both head‐end gear (Master Unit) and remote gear (Remote Units) must be connected to Phase, Neutral and Ground in a proper way before power is connected. The chassis of the remote and the rack of the master unit should be grounded to a potential bar or safety grounding bar when operated.
Installation guidelines Master Unit The Master Unit is designed to be installed in a 19" rack. Before installing, consider cable routing for all cards to be installed in the Master Unit. The installer may want to consider horizontal cable managers to be mounted above and below the Master Unit to aid in the installation and ongoing maintenance of the system. Each card in the Master Unit will require an Ethernet connection to the BGW in order to be programmed and monitored.
Fiber Distributed Antenna System (Fiber DAS) Power Supply Unit Bird Technologies offers two different power supplies for the Master Unit: AC (DPU‐301) and DC (DPU‐302). The power supply can be located in a Master Unit other than the one it is powering. Each power supply is shipped with one Molex power supply jumper. If redundant power supplies are required additional power supply jumper(s) will need to be ordered. The power supply uses four slots on the Master Unit.
Installation guidelines PSU DPU-302 The DPU‐302 uses a HAN four prong Heavy Duty Power Connector. The DC to DC DPU‐302 power supply has in input rating of ‐36 VDC to ‐72 VDC. The DPU‐302 requires the installer to provide 18 AWG wire for the HAN 3 A plug kit (Harting P/N 10 20 003 0002) that is provided with the power supply. See Table 59 for connector pinout. The DC power supply can support a single Master Frame Unit with up to 12 cards (BIU, FOI, ICU).
Fiber Distributed Antenna System (Fiber DAS) BIU CAUTION Overdriving the RF source input into the BIU will cause permanent equipment failure and will void the warranty. The installer must ensure that input levels are not exceeded. Plan for maximum power out of the RF source and attenuate accordingly with external attenuators if needed. The BIU serves as the RF interface between the RF source and the ICU/FOI. Each BIU is pre‐set to a frequency band and is not field tunable.
Installation guidelines ICU The ICU is designed to be installed in a 19" rack. The ICU is typically installed directly above or below the Master Unit chassis. Consider post installation changes and testing when selecting a slot to install the ICU. Figure 35 ICU The ICU has QMA connectors. QMA cable kit ‐ Bird part number DCC320 is available for use with the ICU. The kit contains 32 QMA to QMA cables (see Table 60) that can be used to patch between the BIU to the ICU, BIU to the FOI or ICU to FOI.
Fiber Distributed Antenna System (Fiber DAS) RFU The integrated repeater unit, RFU, DMR400 is mounted in the Master Unit chassis. The DMR400 uses two slots in the Master Unit. Figure 37 RFU Connections RF Source Uplink/ Downlink Rebroadcast Powering Up the Head End 1. 2. 3. Apply power to the BGW by pressing the power button on the left side of the unit. The BGW requires approximately 5 minutes to completely boot up.
Installation guidelines Installing Remote Units The remote units are factory configured and should not be opened in the field. WARNING The Remote Units are heavy , use care and always properly support units during installation. If allowed to fall Remote Units can cause injury or death. CAUTION Ensure the surfaces being used to mount Remote Units can safely support the full weight of the remote. The remotes must be mounted in a vertical position.
Fiber Distributed Antenna System (Fiber DAS) Double Remote Unit Wall Mounting Bird Technologies offers a bracket that allows two wall mount racks to be mounted back to back. This reduces the amount of wall space required when two remotes are located together. The bracket is stainless steel and can be used indoors or outdoors.
Installation guidelines Solar Shield Direct exposure to sun light can cause temperatures of the remote to exceed the 55 °C (131°F) rating. A simple solution offered by Bird is to attach an optional solar shield to the affected remotes. The solar shields (p/n DMA301) are sold separately. Figure 41 Remote Unit Solar Shield Cabling There are many options for the Bird remotes which can affect the number of connections on the bottom of each remote.
Fiber Distributed Antenna System (Fiber DAS) Ethernet Port The RJ45 Ethernet port is located on the bottom panel of the remote unit. Connection of the Ethernet port is not required for normal operation of the DAS. The port offers convenient access to the system GUI during installation, commissioning and troubleshooting of the DAS. Ensure the provided IP67 rated protective cap is replaced when the Ethernet port is not in use.
