ADCP-75-210 • Issue 1 • November 2006Page 9© 2006, ADC Telecommunications, Inc.1.6.2 Fiber Optic Cable EntryA nylon connector is provided on the rear of the RAN cabinet for routing a fiber optic cable intothe cabinet. The cord connector provides cable strain relief and a watertight seal at the fiberoptic cable entry point. As the connector nut is tightened, a soft neoprene bushing compresses totightly grip the cable without applying excessive force to the fibers. The connectoraccommodates cables of a diameter in the range .38 to .50 inches (.97 to 1.27 cm).In a typical installation, the connectorized end of a multi-fiber OSP cable is routed into thecabinet through the cord connector and the individual fibers are connected to the opticaltransceiver on the Synchronous Interface Card (SIF). Excess slack is stored inside the cabinet.The stub end of the cable is routed to an external splice enclosure (not provided) for splicing tothe outside plant fiber optic cable. 1.6.3 Antenna Cable ConnectionsFive N-type plugs are provided on the rear of the RAN cabinet for connecting the antennacoaxial cables. On the inside of the cabinet, coaxial jumper cables (included with the cabinet)are used for connecting to the antenna port on the appropriate multiplexer.1.6.4 AC Power Wiring Entry and GroundingThe NXD RAN uses 240 VAC power. A one inch (2.54 cm), 90 degree rigid elbow conduitfitting is provided on the rear of the cabinet. The conduit should be routed to an externaljunction box (not provided). It is suggested that an external AC outlet (not provided) be installednear the cabinet to power test equipment and power tools. The AC source should supply 50/60Hz, single-phase power through a circuit breaker rated at 20 Amps.1.6.5 VentilationVentilation openings are provided in the front door of the RAN cabinet to permit entry of air forcooling. A filter removes dirt particles so that only clean air enters the cabinet. The heated airexits the cabinet through the rear side. The four PAAs are each equipped with three cooling fansthat pull air through the module and exhaust it to the rear of the cabinet. A fan assembly at thetop of the RAN chassis forces the air out the rear side of the cabinet.Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushingsthat fit this connector in the following size ranges: .500-.625, .625-.750, .750-.875, .875-1.00, 1.00-1.125 inches.

ADCP-75-210 • Issue 1 • November 2006Page 11© 2006, ADC Telecommunications, Inc.Figure 7 is a schematic showing the data flow in the RAN chassis. As shown, data flows in twodirections, from the Hub through the RAN to the antenna, and from the antenna through theRAN back to the Hub. In each direction, data conversion occurs, with optical data“upconverted” to RF data in the up direction in the schematic, and RF data “downconverted” tooptical data in the down direction. In an up direction, the RUC module converts DigitizedIntermediate Frequency (DIF) data into PCS, Cellular, and SMR frequency RF bands. The RFsignals are amplified and then transmitted from the RF antenna. In the down direction, the RDCmodule converts PCS, Cellular, and SMR frequency bands into DIF data. The overall series ofevents is managed by the CPU using an Ethernet connection to the chassis backplane.Figure 7.

ADCP-75-210 • Issue 1 • November 2006Page 30© 2006, ADC Telecommunications, Inc.Digivance NXD Multi-Band Distributed Antenna System Operation Manual (ADCP-75-209)for system turn-up and test procedures.The procedures in this section assume that the required Outside Plant (OSP) fiber optic cablehas already been routed between the Hub and the RAN, that the required antenna has beeninstalled, and that a coaxial cable terminated with an N-type connector has been routed to theRAN from the antenna.2.1 Installation OverviewA standard (typical) installation of the RAN consists of the following steps: 1. Checking out and preparing the installation site. 2. Unpacking and inspecting the shipped items. 3. Installing a pole mount frame or pedestal mount.4. Installing the RAN cabinet on the pole or pad.5. Installing the rain shields (pole mount) or pedestal enclosure (pad mount).6. Installing the solar shield.7. Installing a ground wire.8. Connecting RF cables between the antenna and RAN. 9. Installing the fiber optical cable that connects the RAN to the Hub.10. Installing AC power.11. Installing backup batteries in the cabinet. Danger: Wet conditions increase the potential for receiving an electrical shock when installingor using electrically-powered equipment. To prevent electrical shock, never install or useelectrical equipment in a wet location or during a lightning storm.Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtailswithout severe bends. Some fiber optic patch cords or pigtails may be permanently damaged ifbent or curved to a radius of less than 2 inches (50 mm).Warning: Electronic components can be damaged by static electrical discharge. To preventESD damage, always wear an ESD wrist strap when handling electronic components.Note: To insure that all optical connectors and optical ports remain dust-free duringinstallation, leave all dust caps and dust protectors in place until directed to remove themfor installation.
ADCP-75-210 • Issue 1 • November 2006Page 31© 2006, ADC Telecommunications, Inc.2.2 Unpacking and InspectionThe RAN is shipped to the field pre-configured with all modules and components that thecustomer has ordered. Electronic modules except for the batteries are shipped already installedin the cabinet.The following optional accessories may also be shipped with the RAN:• Back-up batteries• Non-standard SFP optical transceiverUse the following procedure to unpack and inspect the RAN components: 1. Open the shipping cartons and carefully unpack each component from the protectivepacking material. 2. Check each component for broken or missing parts.

ADCP-75-210 • Issue 1 • November 2006Page 32© 2006, ADC Telecommunications, Inc.The following tools are required to perform this procedure:• Torque wrench• Drill• Drill bit (appropriate for pole width and 3/4 in. bolts)• 7/16 in. open-end wrench• Compression pliers for #6 AWG grounding lug• Wire cutters• Wire strippers• Conduit cutter• Conduit bender2.4 Site PreparationThis section describes site preparation for installation and is presented only as a guideline for atypical RAN installation.2.4.1 Space RequirementsWhen an installation site for the RAN is selected, either on a utility pole or concrete pad, caremust be exercised to ensure that the site provides adequate space and clearance to accommodatethe current installation and any future upgrades. Table 17 gives RAN dimensions. 2.4.2 Power RequirementsPower must be available at the RAN site. The RAN requires 240 VAC, single phase, 20 Ampsservice. Included with the power meter must be surge protection and circuit breakers. The RAN can have up to three 1500 watt rectifiers. For the minimum specified voltage (176VAC), each can draw up to 10 amps. The RAN will draw up to 1800 watts normally, but whenbatteries are re-charging that amount will increase the current draw into a RAN to up to 16Amps. Therefore, one 20 Amps service is required per four band RAN.Table 17. RAN DimensionsCONFIGURATION WIDTH HEIGHT DEPTHRAN 31.35 in. (76.7 cm) 36.5 in. (92.7 cm) 27.5 in. (69.9 cm)Dual RAN 31.25 in.

ADCP-75-210 • Issue 1 • November 2006Page 33© 2006, ADC Telecommunications, Inc.In a pole mount installation, the power meter is typically installed on the pole below the unit inseparate boxes. In a concrete pad installation, an external junction box is typically placed nearthe RAN providing AC power, surge protection, and circuit breakers. 2.4.3 Antenna RequirementADC offers a pole-mount antenna kit (accessory) for use when the RAN is mounted on awooden utility pole. Either a 2 in. (5.08 cm) O.D. model or a 9 in. (22.86 cm) O.D. model canbe ordered. Pole mounting is the most common installation. The antenna interfaces with thePCS and Cellular/SMR bands and supports two branch diversity receive paths. Also included inthe kit is the GPS antenna used by the RAN. Installation instructions for the pole mount antennaare included with the kit.When the RAN is mounted on a concrete pad, a conventional directional antenna may be used(customer supplied). The antenna may be set to operate in either a sector or quasi-omniconfiguration, depending on the coverage objective and design. Proper antenna selection and themounting installation are the responsibility of the design engineer. 2.4.4 RF Cable RequirementsRF cables are required at the installation site to provide the physical link between the RAN andthe antenna. In a pole-mount installation, U-duct of an appropriate size is also required to coverthe RF cables on the pole. The U-duct provides only physical protection. It should not beconsidered to provide electrical isolation from conductors on the pole. Adequate clearance mustbe obtained for the routing of these cables past the existing services as defined in the previoustopic. In a concrete pad installation, RF cables from the antenna are routed and protected per theinstallation plan provided by the design engineer.2.4.5 Fiber RequirementsOptical fibers are required at the site to provide the physical link between the RAN and the Hub.In a typical installation, the identified fibers are broken out of a multi-fiber sheath and routed toa splice box where they are spliced to pigtails connecting the main sheath to the RAN. Theactual fiber bundle location on the utility pole may vary per the agreed to attachment point.Refer to Figure 24. The nylon cable connector on the rear of the RAN accommodates cables ofa diameter in the range .38 to .50 inches (.97 to 1.27 cm). For larger size cables, refer toSection 1.6.2 on Page 9.

Per theNational Electrical Safety Code, vertical clearance at supports for primary-supply conductorsabove other facilities is required to be 16 in. (40.64 cm) above neutrals and 40 in. (101.6 cm)above communications (60 in. [152.4 cm] if above 8700V).For supply conductors at voltages up to 8700 between conductors, the minimum horizontalclearance provided by the NESC ANSI C2 is 12 in. (30.5 cm). For higher voltages, it is requiredthat .4 in. (10.2 mm) be added for every 1000V above 8700. Table 18 lists the requiredclearances for some common high voltages.This information is from the Standard Handbook for Electrical Engineers, 13th Edition,McGraw Hill, Chapter 18, Section 151, Pages 18-65.Table 18.

ADCP-75-210 • Issue 1 • November 2006Page 48© 2006, ADC Telecommunications, Inc.All fiber optic cable connections require single-mode Dual-LC type connectors. Figure 33 shows the basic configuration of the optical path between the Hub SIF and the RANSIF. For optical specifications, refer to Table 2 on page 6.Figure 33. Optical Path Between Hub SIF and RAN SIFFor fiber cable ingress, the RAN is equipped with a nylon fiber optic connector located on therear side of the cabinet. The connector accommodates cables of a diameter in the range .38 to.50 inches (.97 to 1.27 cm).Use the following procedure to install the fiber optic cable:1. Route the connectorized end of the fiber optic cable from the splice enclosure (notprovided) to the rear side of the cabinet. Estimated length of cable is 30 feet (9 meters)although this is dependent upon distance from the splice enclosure. Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushingsthat fit this connector in the following size ranges: .500-.625, .625-.750, .750-.875, .875-1.00, 1.00-1.125 inches. Note: The routing of an Outside Plant (OSP) fiber optic cable from the Hub to a spliceenclosure in the vicinity of the RAN cabinet and the splicing of selected OSP cable fibersto the fibers in the outdoor-rated cable is the responsibility of the installer.Warning: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook 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 MUSTbe immediately placed over any radiating transmitter or optical fiber connector to avoid thepotential of dangerous amounts of radiation exposure. This practice also prevents dirt particlesfrom entering the connector.FIBER PORTTX RXFIBER PORTTX RXREVERSE PATHBASIC CONFIGURATION BETWEEN HUB SIF SFP AND RAN SIF SFPEND-TO-END OPTICAL CONNECTOR/CABLE ASSEMBLY DIAGRAMFORWARD PATH21353-A
