ADCP-75-348 • Issue 1 • 04/2008Page 1© 2008, ADC Telecommunications, Inc.1 GENERALThe FlexWave URH product family of products is intended as a “next generation” distributed antenna system (DAS). DAS products provide bidirectional transport of digitized RF spectrum. Each link consists of a host unit (providing the interface between the base station RF ports and the optical fiber) and at least one remote unit (providing the interface between the optical fiber and the remote antenna). The difference in this product is the high-speed digitalization of a wideband portion of spectrum, that allows for transport of RF signals over extended distances, without the RF degradation that normally results when analog systems are impacted by optical effects.The basic function of the FlexWave URH platform is to transport via fiber optic cable RF signals form a Base Transceiver Station (BTS) to an antenna interface allowing communication to a mobile device. Multiple BTS communication paths are allowed over a single URH system. Diversity receive is supported. A block diagram of the system is shown in Figure 1.Figure 1. FlexWave URH Block DiagramThe basic function of the FlexWave URH simulcast (point-to-point) platform is to transport, via fiber optic cable, RF signals form a Base Transceiver Station (BTS) to multiple antenna interfaces allowing communication to a mobile device. Up to 8 simulcast remotes are supported.FlexwaveURHHOSTFWD RF INREV RF OUTBTS 1FlexwaveURHREMOTEANTENNAINTERFACEBTS 1BTS 2BTS 3ANTENNAINTERFACEBTS 2ANTENNAINTERFACEBTS 3NON-DIVERSITYFlexwaveURHHOSTFWD RF INREV RF OUTBTS 1FlexwaveURHREMOTEANTENNAINTERFACEBTS 1BTS 2BTS 3ANTENNAINTERFACEBTS 2ANTENNAINTERFACEBTS 3DIVERSITYREV DIV RF OUTFWD RF OUTREV RF INREV DIV RF INFWD RF OUTREV RF INREV DIV RF INFWD RF OUTREV RF INREV DIV RF INFWD RF INREV RF OUTREV DIV RF OUTFWD RF INREV RF OUTREV DIV RF OUTFWD RF INREV RF OUTFWD RF INREV RF OUTFWD RF OUTREV RF INFWD RF OUTREV RF INFWD RF OUTREV RF IN22380-A
ADCP-75-348 • Issue 1 • 04/2008Page 2© 2008, ADC Telecommunications, Inc.2 INTRODUCTIONThe front access URH Host Unit interfaces with the BTS and performs the analog to digital and electrical to optical conversions for transport to the URH Remote Units. A typical URH system consists of a Host Unit (HU) and a Remote Unit (RU). The HU is designed for maximum RF flexibility to address Carriers changing and evolving spectrum needs, making the most use of cost efficient resources for serving multiple remotes such as simulcast architecture and sharing of common functions such as power, control and management over multiple host units. These features are designed into a compact package that reduces the amount of overall rack space required within a BTS Hotel. Each host chassis can support up to eight RUs.The HU is a three rack-unit high single-unit assembly that mounts in a standard equipment rack. The RU consists of an outdoor enclosure that houses various electronic components. The RU is a modular self-contained enclosure. Together the HU and the RU together comprise an URH system. Various accessory items are also available for use with each system. All items referenced as “accessory items” are not furnished and must be purchased separately.3 HOST UNIT DESCRIPTIONA front view of the HU, shown in Figure 2, consists of an electronic circuit board assembly and a fan assembly that are mounted within a powder-paint coated sheet metal enclosure. The enclosure provides a mounting point for the circuit board and fan assembly and controls RF emissions. Fan assembly can be replaced in the field. Host Unit may be upgraded once it is installed to support additional URH Remote Units. This can be performed without disrupting service.Figure 2. Front View Host UnitThe HU is designed for use within a non-condensing indoor environment such as inside a wiring closet or controlled environment cabinet. All controls, connectors, and indicators (except the grounding point) are mounted on the HU front panel. Current versions of the HU allow vertical cable guides to be installed over the mounting brackets on either side of the HU.

RJ45 Connector Wiring3.2.2 Craft Interface ConnectionSeRF front panel provides a craft port that can be used to provision remote units through the optical protocol supported by a single RJ-45 connector. The Craft connector provides an Ethernet interface. Craft interface connection between the HU and the network is supported by a RJ-45 jack 10/100Base-T (IEEE802.3 compliant) with integrated green ACTIVITY and LINK LEDs. The Ethernet port supports a maximum cable length of 100 meters (328 feet) to a hub or back-to-back nodes. CAT5 or better cable should be used when making this connection.1. The IEEE Specification for Ethernet 100BaseT requires that two twisted pairs be used and that one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6.2. Pinout information is shown in Table 1. See Figure 3 for RJ45 connector wiring information.3.2.3 Optical InterfaceOptical connections between the HU SeRF card and the RU are supported through Small Form-factor Pluggable (SFP) transceivers. The optical interfaces are standard single-mode duplex LC (flat polished UPC). There are 8 duplex optical interfaces, one for each simulcast remote.3.3 DART CardThe host DART provides the interface between base station equipment and the SeRF. It is a band specific assembly and exists in the following versions:• Cellular•SMR 800•SMR 900•PCSThe following features and capabilities are available on the DART Card:• Amplifies, down-converts, filters and digitizes from a 1.5MHz to 35MHz band of the incoming RF signalRJ-JACKPIN 1PIN 811899-A

ADCP-75-348 • Issue 1 • 04/2008Page 11© 2008, ADC Telecommunications, Inc.6.3 OSP Fiber Cable Installation GuidelinesThe outside plant (OSP) fiber optic cables should be routed between the HU distribution panel and RU outside plant cabinet and terminated before the equipment is installed. A diagram of a typical OSP cable routing is shown in Figure 7. At the HU, the OSP cable should be terminated at a fiber distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the HU optical ports to the OSP cable terminations. Whenever possible, a guideway such as the FiberGuide system should be provided to protect the fiber optic patch cords from damage and to prevent excessive bending. The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 6.8. Figure 7.

If the application does not require the use of a WDM system, skip this section and proceed to Section 6.5. The WDM host module mounting shelf installs in the equipment rack with the HU. Each host module mounting shelf can hold multiple modules and each host module can support two HU’s. When multiple HU’s require connection to a WDM system, the host module mounting shelf and the HU’s should be mounted in the equipment rack as shown in Figure 8. This configuration allows the pigtail leads from the two host modules to be connected directly to the optical ports on any one of the four HU’s. Figure 8. Typical WDM and HU ConfigurationThe WDM host module mounting shelf may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Four #12-24 screws are provided for securing the mounting shelf to the rack.

Both US standard and metric machine screws are included for rack mounting the HU. When loading the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack. The rack should safely support the combined weight of all the equipment it holds. In addition, maximum recommended ambient temperature for the HU is 55º C (131º F). Allow sufficient air circulation or space between units when the HU is installed in a multi-rack assembly because the operating ambient temperature of the rack environment might be greater than room ambient. 22393-A
ADCP-75-348 • Issue 1 • 04/2008Page 14© 2008, ADC Telecommunications, Inc.Use the following procedure to install the HU in the equipment rack:1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If mounting the HU in a 19-inch rack, proceed to Step 4. If mounting the HU in a 23-inch rack, proceed to Step 2. 2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit) and save screws (six-screws on each side) for reuse. 3. Reinstall both mounting brackets so the short side of the bracket is flush with the HU front panel as shown in Figure 10. Use the screws removed in Step 2 to re-attach the brackets to the HU chassis. Figure 10. Installing the Mounting Brackets for 23-Inch Rack Installations4.

ADCP-75-348 • Issue 1 • 04/2008Page 16© 2008, ADC Telecommunications, Inc.6.7 Coaxial Cable ConnectionsThe RF interface between the HU DART card and the EBTS/BTS is supported through two type QMA female connectors mounted on each DART front panel. One connector provides the coaxial cable connection for the forward path (downlink) signal and the other connector provides the coaxial cable connection for the reverse path (uplink) signal. In most installations, it is usually necessary to insert an external attenuator into the forward path link between the HU and the BTS. A signal level that is greater than –9 dBm will overdrive and possibly damage the HU receiver. Before completing the forward path connection at the BTS, verify that the composite forward path RF signal level at the HU is between –25 and +5 dBm.The HU should be mounted as close as possible to the EBTS/BTS to minimize cable losses. Use the following procedure to route and connect the forward and reverse path coaxial cables to the HU DART cards:1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial communications cable (RG-400 or equivalent) for all coaxial connections. 2. Route the forward and reverse path coaxial cables between the HU and the BTS interface (per system design plan) and cut to the required length. Allow sufficient slack for dressing and organizing cables at the HU and for installing an external attenuator in the forward path link. 3. Terminate each cable with an QMA-Type male connector following the connector supplier’s recommendations. 4. If required, install an external attenuator in the forward path. 5. Connect the forward path cable to the FWD RF IN connector on the HU DART front panel as shown in Figure 12. 6. Connect the reverse path cable to the REV RF OUT connector on the HU DART front panel (see Figure 12). 7. Repeat this procedure for the remaining DART cards in the HU.8. Dress and secure cables at the right side of the HU.9. Complete all remaining coaxial connections as specified in the system design plan. Note: The composite forward path RF signal level at the HU must be between –25 and +5 dBm. Do not connect the forward path cable until the composite forward path RF signal level is measured and the amount of external attenuation required is determined.
ADCP-75-348 • Issue 1 • 04/2008Page 17© 2008, ADC Telecommunications, Inc.Figure 12. Forward and Reverse Path Coaxial Cable Connections6.8 Optical ConnectionsThe optical interface between the HU and the RU is supported by optical ports. Each optical port consists of an SFP with LC optical transceivers mounted on the SeRF card front panel. Each FWD port provides an optical connection for the forward path (downlink) signal. Each REV port provide an optical connection for the reverse path (uplink) signal. Each REV port can also provide the optical connection for the diversity reverse path (uplink) signal. The optical connections are dependent on whether or not a WDM host module (accessory) is installed: • If the installation does not include a WDM module, proceed to Section 6.8.1 for the optical connections procedure. • If the installation includes a WDM module, proceed to Section 6.8.2 for the optical connections procedure. 22411-A
ADCP-75-348 • Issue 1 • 04/2008Page 18© 2008, ADC Telecommunications, Inc.6.8.1 Optical Connections Without WDM SystemUse the following procedure to connect the optical fibers when there is no WDM installed with the HU:1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber distribution panel. 2. Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to the connector. 3. Remove the dust caps from the HU SeRF SFP optical ports and from the patch cord connectors that will be connected to the SeRF SFP optical ports. 4. Clean each patch cord connector following the patch cord supplier’s recommendations. 5. Insert each patch cord connector into the appropriate optical port as shown in Figure 13and as specified by the following:PORT 1 FWD - Forward path patch cordPORT 1 REV - Reverse path patch cord6. Route the patch cords from the HU to the fiber distribution panel. 7. At the fiber distribution panel, identify the OSP cable optical fiber terminations that correspond to the forward and reverse paths. 8. Remove the dust caps from the OSP cable optical fiber adapters and from the patch cord connectors. 9. Clean each patch cord connector (follow patch cord supplier’s recommendations) and then mate the connector with the appropriate OSP cable adapter. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. When the system is turned-up and tested, the attenuator may be resized or removed.Caution: Improper handling can damage fiber optic cables. Do not bend fiber optic cable more sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not apply more pulling force to the cable than specified.Note: The HU optical adapters are angled to the left. Therefore, always route patch cords to the HU from the left side of the rack. Routing patch cords to the HU from the right may exceed the bend radius limitations for the optical fiber.
