This equipment complies with the applicable sections of RSS-131. The term “IC:” before the

radio certification number only signifies that Industry Canada Technical Specifications were met.

The Manufacturer's rated output power of this equipment is for single carrier operation. For

situations when multiple carrier signals are present, the rating would have to be reduced by 3.5

dB, especially where the output signal is re-radiated and can cause interference to adjacent band

users. This power reduction is to be by means of input power or gain reduction and not by an

attenuator at the output of the device.

Caution: Modifications not expressly approved by the party responsible for compliance could

void the user's authority to operate the equipment.

Note: To comply with Maximum Permissible Exposure (MPE) requirements, the maximum

composite output form the antenna cannot exceed 1000 Watts ERP (Cellular and SMR), the

1 GENERAL

The 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 Diagram

The 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.

2 INTRODUCTION

The 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 DESCRIPTION

A 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 Unit

The 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.

3.1 Mounting

The HU is intended for rack-mount applications. A pair of reversible mounting brackets is

provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO

equipment rack. When installed, the front panel of the HU is flush with the front of the rack.

Screws are provided for securing the HU to the equipment rack.

3.2 SeRF Card

3.2.1 Network Interface Connection

SeRF front panel has an Ethernet port allowing interface communication with the internal

processor and transfer of data to the optical protocol allowing IP transport between the HU and

the remote(s). The network interface allows the HU to be controlled through a network.

Network 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. The Ethernet

connection should not be connected to an Ethernet circuit used outside the building.

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.

• Converts incoming digital signal to analog, filters, amplifies and up-converts

• Provides bi-directional interface between parallel digital RF (to D/A and from A/D) and

Serial RF (SeRF) to/from SeRF board

• Performs digital up/down conversion and adjustable delay processing

• Non-contiguous bands and receive diversity is implemented with multiple DART Cards

3.3.1 RF Signal Connections

The RF signal connections between the HU DART cards and the BTS are supported through

two (FWD RF IN and REV RF OUT) QMA-Type female connectors. One connector is used for

the forward path RF signal. The other connector is used for the reverse path RF signal. In some

installations, it may be necessary to install a Conditioning Panel and/or Duplexing Panel

(accessory items) to support the interface between the HU and the BTS. The HU should be as

close as possible to the BTS to minimize cable losses.

3.4 System Card

The System Interface Card gives additional front panel space for the SeRF card. The System

Card front panel also provides connections for alarm outputs, 10 MHz output, and status LEDs.

This card may be used to provide a 10 MHz clock reference to which the SeRF's Master clock is

frequency locked from the internal crystal oscillator. When the internal clock is not used the

clock can be obtained from an external 10 MHz input.

3.5 Power Supply

HU is powered by a modular DC to DC power supply located on the lower left side of the

chassis. An On/Off switch is provided on the HU power supply module front panel.

HU is powered by ± 20 to ± 60 VDC power (nominal ± 24 or ± 48 VDC), power is fed to the HU

through a connector located on the front of the module. Power to the HU must be supplied

through a fuse panel (available separately). Each HU must be protected with a fuse.

3.6 User Interface

The HU user interface consists of the various connectors, switches, terminals, and LEDs that are

provided on the HU front panel. The HU user interface points are indicated in Figure 4 and

described in Table 2.

6.3 OSP Fiber Cable Installation Guidelines

The 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.

6.4 WDM Host Module Mounting Shelf and WDM Host Module Installation Procedure

A bi-directional wavelength division multiplexer (WDM) system is available as an accessory

item for the URH system. 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 Configuration

The 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. Use the following procedure to install the WDM host module mounting shelf in the

equipment rack and to mount the WDM modules in the WDM host module mounting shelf:

fastener 90º.

7. Carefully store the pigtail leads from each host module. The routing and connection

procedures for the pigtails are provided in Section 6.8.

6.5 HU Mounting Procedure

The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment 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 • 04/2008

Page 14

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 Installations

4. Position the HU in the designated mounting space in the rack (per system design plan) and

then secure (but do not tighten) the HU to the rack using the four machine screws provided

(use #12-24 or M6 x 10 screws, whichever is appropriate).

5. Locate two vertical cable guides, not provided with the HU.

Warning: Wet conditions increase the potential for receiving an electrical shock when

installing or using electrically powered equipment. To prevent electrical shock, never install or

use electrical equipment in a wet location or during a lightning storm.

Note: To insure that all optical connectors remain dust-free during installation, leave all dust

caps and dust protectors in place until directed to remove them for connection.

Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and

right sides of the HU for air intake and exhaust.

Note: A vertical cable guide kit is available separately as an accessory.

6.7 Coaxial Cable Connections

The 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 • 04/2008

Page 17

Figure 12. Forward and Reverse Path Coaxial Cable Connections

6.8 Optical Connections

The 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 • 04/2008

Page 18

6.8.1 Optical Connections Without WDM System

Use 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 13

and as specified by the following:

PORT 1 FWD - Forward path patch cord

PORT 1 REV - Reverse path patch cord

6. 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.

10. Repeat this procedure for the remaining SeRF SFPs in the HU.

11. Store any excess patch cord slack at the fiber distribution panel or storage panel.

6.8.2 Optical Connections For Systems With a WDM

Use the following procedure to connect the optical fibers when a WDM module is installed with

the HU:

1. Obtain a patch cord that is of sufficient length to reach from the WDM module to the fiber

distribution panel.

2. Remove the dust cap from WDM Port or Port 4 on the WDM module and from the patch

cord connector that will be connected to the WDM module.

Note: WDM module ports are labeled FWD, REV, TEST, and WDM.

6.9 EXT REF Connections

EXT REF connections between multiple HU’s is supported through two QMA type female

connectors mounted on the System card. One of the jacks is designated as the IN port and the

other jack is designated as the OUT port. The EXT REF interface allows HU’s to be connected

together (in daisy-chain fashion) and clocked through a single source. Use the following

procedure to connect EXT REF interface cables between multiple HU’s:

1. Connect one end of the EXT REF interface cable (accessory) to either the IN or OUT port

on HU #1 as shown in Figure 15.

Figure 15. EXT REF Connections

2. Route the EXT REF interface cable to HU #2 and connect the cable’s free end to the port

that is the logical opposite of the EXT REF interface connection at HU #1.

Note: The HU SeRF SFP optical adapters are angled to the left. Therefore, pigtails should

always be routed to the HU from the left side of the rack. Routing pigtails to the HU from

the right side of the rack may exceed the bend radius limitations for the optical fiber.

Note: When using the 10 MHz external reference clock the signal must be connected to

the HU before enabling the clock source in the software.

3. If a third HU will be connected to the network, connect a second EXT REF interface cable

to the remaining network port on HU #2.

4. Route the second EXT REF interface cable to HU #3 and connect the cable’s free end to

the port that is the logical opposite of the EXT REF interface connection at HU #2.

5. Repeat steps 3 and 4 for each additional HU that is added to the network. A diagram of

typical EXT REF interface connections is shown in Figure 16.

Figure 16. Configuring EXT REF Connections with Multiple Host Units

6.10 Computer Connection (CRAFT)
