4. Danger: Due to power dissipation, the remote unit may reach a very high
temperature. Do not operate this equipment on or close to flammable materials.
Use caution when servicing the unit.
5. Warning: Read and obey all the warning labels attached to the unit. Make sure
that all warning labels are kept in a legible condition. Replace any missing or
damaged labels.
6. Warning: It is the responsibility of the network provider to implement prevention
measures to avoid health hazards associated with radiation from the antenna(s)
connected to the unit.
7. Warning: Make sure, access is restricted to qualified personnel.
8. Warning: Only license holders for the respective frequency range are allowed to
operate this unit.
9. Warning: Make sure the repeater settings are correct for the intended use (refer
to the manufacturer product information) and regulatory requirements are met.
10. Warning: Use this equipment only for the purpose specified by the manufacturer.
Do not carry out any modifications or fit any spare parts, which are not sold or
recommended by the manufacturer. This could cause fires, electric shock, or
other injuries.
11. Warning: For installations, which have to comply with FCC RF exposure
requirements, the antenna selection and installation must be completed in a way
to ensure compliance with those FCC requirements. Depending on the RF
frequency, rated output power, antenna gain, and the loss between the repeater
and antenna, the minimum distance D to be maintained between the antenna
location and human beings is calculated according to this formula:

2. Introduction
2.1. Purpose
Mobile telephone and public safety systems transmit signals in two directions
between base transceiver station (BTS) and mobile stations (MS) within the signal
coverage area to carry voice and data traffic.
If weak signal transmissions occur within the coverage area because of indoor
applications, topological conditions or distance from the transmitter, extension of the
transmission range can be achieved by means of an optical distributed antenna
system (DAS).
Office buildings, sports arenas, college campuses, industrial parks, and other areas
of high demand require the specialized capacity boost that an optical DAS can
provide to meet increasing customer demands for voice and data.
An optical DAS contains optical Master Units and a sufficient number of Remote
Units to provide the necessary coverage. The number of the Remote Units depends
on the coverage requirements of the DAS. The Remote Units are connected to the
Master Unit with optical links.
The Master Unit is the connection to the Base Transceiver Stations. The
configuration of a Master Unit depends on the number of the Remote Units and the
frequency range.
RF signals are transported to and from the remote units via optical fibers.
2.2. ION-U High Power Remote Units
The ION-U is an optical fiber based DAS system that efficiently takes the outputs of
multiple Base Transceiver Stations (BTS) sectors and converts those RF signals to
optical to send them over fiber optic cables to remote units to provide coverage in
indoor and outdoor locations. The system supports both low power and high power
remotes units and SISO and MIMO operation.
The ION-U H 17P2 is a multi-band, multi-operator high power remote unit optimized
for CDMA2000, EV-DO, WCDMA, HSDPA, and OFDM modulation in the 1700 MHz
band. It is provisioned for future modulation and frequency bands. These Remote
Units feature independent downlink and uplink gain adjustments and an integrated
channel power detector for in-band spectrum and PIM analysis and end-to-end auto
leveling.
The unit utilizes a single fiber to support multiple bands in both the uplink and
downlink directions. WDM (Wave Division Multiplex) filters are integrated in the
optical modules. For the UL, a wavelength within 1546 nm – 1550 nm is used. For
the DL, a wavelength of 1310 ±10 nm is used. The maximum output power for the UL
and DL is 6.7 mW.

3. Functional Description
3.1.1. eCPD+ (Enhanced Channel Power Detector plus)
The enhanced Channel Power Detector plus (eCPD+) is a remote-controlled data
acquisition system for monitoring the RF output power of the RU at the air interface.
These measurements are monitored by the master unit.
3.1.2. Fan Protection Kit
In order to protect the fan unit in outdoor use (e.g. against rain), a protective cover is
delivered with the unit that can be mounted over the fan unit. For indoor applications,
mounting of the fan protection kit is not mandatory.
3.1.3. Accessories
A number of accessories are available for the Remote Unit such as shrouded
housing, connecting boxes, and iso-trafo kits.
A short version of the Remote Unit designed to be mounted in a protective shroud is
also available. The shroud provides protection for the Remote Unit, an Extension
Unit, and an optional cross-band coupler. The short versions of the RU and EU are
required when using the shroud.

The selection of cable and antenna is an important consideration. On the one hand, a
cable with higher loss is less expensive but, on the other hand, it impairs
performance.
Use an appropriate torque wrench to tighten the 7/16 DIN-type (1 ¼ -inch
opening) antenna connectors to a coupling torque of 25 N-m / 19 ft lb.
Torque wrench item no. 244377, available from the CommScope e-
catalog, is recommended. Do NOT use your hands or any other tool (e. g.
a pair of pliers)! This might cause damage to the connector and lead to a
malfunction of the Remote Unit or increased PIM.
To minimize passive inter-modulation (PIM) distortion, attention must be
paid to the physical condition of the connector junctions. Do not use
connectors that show signs of corrosion on the metal surface. Prevent
the ingress of water into the connector. Attach and torque the
connectors properly.

4.2.10. Optical-Fiber Cable Connection
Rules for Optical-Fiber Connection
Optical signals are transmitted by use of optical fibers. When connecting these fibers
observe the following instructions.
Note: Care should be taken when connecting and disconnecting fiber-
optic cables. Scratches and dust significantly affect system
performance and may permanently damage the connector. Always
use protective caps on fiber-optic connectors not in use.
In general, optical fibres do not need special protective measures. However,
protection against environmental influences e.g. rodents and humidity must be
considered.
The optical fibre is a single mode fiber. Type is E9/125 µm with the following
minimum requirements:
Attenuation: <0.36 dB / km @ 1310 nm / <0.26 dB / km @ 1550 nm
Dispersion: <3.5 ps / nm km @ 1310 nm / <18.0 ps / nm km @ 1550 nm
The specified bending radius of the optical fibers must not be exceeded. The pigtails
for the connection between master unit and remote unit must have a sufficient length.
The fibers must be protected where they enter the units. The system attenuation of
the optical fibers, including the connectors, must not exceed 10 dB.
System attenuation and attenuation of optical components must be determined. This
can be achieved by measuring attenuation and reflection with an appropriate
measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference
plug) can be assumed due to the dead zone of the reflectometer. These
measurements must be made with a sufficient length of optical fiber, at the input and
output of the device which has to be measured.
Fiber-cable connectors have to be of the same type (Radiall Opus LC-APC) as the
connectors used for the unit. The fiber-optic cables are connected to the optical
transceiver.
Angled connectors are not compatible with straight optical connectors;
non-compatibility of connectors will result in permanent damage to
both connectors.

Before connecting the fiber cables, follow the procedure below to ensure optimized
performance. It is important for these procedures to be carried out with care:
Remove fiber-optic protective caps.
Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause
cable damage and interrupt transmission.
Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of
the fiber-optic cable that will be inserted in the optical connectors on the donor
interface box.
Blow out the laser receptacle with clean and dry compressed air to remove
any particulate matter.
Do not use any index-matching gels or fluids of any kind in these connectors.
Gels are intended for laboratory use and attract dirt in the field.
Connect the fiber-optic cables by following the instructions in the next chapter.
4.2.11. Assembly Instructions for Optical LC Patch Cables
The RU optical connector (Opus Short Plug kit) supports both simplex (one fiber
cable) and duplex (two fiber cables) operation. The ION-U H 17P2 utilizes a single

5. Alarms
5.1. Bite and Alarms
The Built-In Test concept comprises the monitoring of the power supplies, the power
amplifiers and the optical interface.
All occurring alarms can be checked via software at the master unit.
5.2. Handling of Alarms
As soon as the software acknowledges a valid alarm, a message is transmitted to the
master unit.
If the reason for the alarm has been cleared or if the alarm should continue, a new
alarm message will not be repeated. If there was an interruption of at least five
seconds after acknowledgement, a new alarm message will be generated.
5.3. Alarm Status
For details refer to the corresponding software documentation of the master unit.
5.4. Status LED Alarms
For local supervision, a status LED on the connector flange of the remote unit
provides a visual indication of possible reasons for alarms. This table shows possible
on-site measures that could be checked before referring to the master unit alarm list.
For local supervision, a status LED on the connector panel of the remote unit
provides a visual warning of an alarm condition. The color of the LED indicates the
severity of the alarm. Detailed alarm information is available through the ION-U
software interface. This table lists the alarm conditions and possible on-site
measures that could be performed to resolve the issues responsible for triggering the
alarms.

5.5. External Alarm Inputs and Outputs
The eight-pin EXT ALARM IN/OUT connector supports two external alarm inputs and
two external alarm outputs. Chapter 4.2.7 Ext. Alarm In / Out Port includes the
connector’s pin-out information and chapter 4.2.2 Connections identifies the
connector’s location.
The alarm outputs (open collector output 5 V / 1 mA) are normally low. In case of an
alarm they are high active (5 V). They can be used to monitor alarms with an external
alarm indicator.
Note: The manufacturer / supplier of this system accepts no liability for
damage caused by equipment connected to external outputs or by
effects from such equipment.
With the external alarm inputs, it is possible to monitor the status of connected
devices, e.g. a UPS, via software. All alarm inputs are normally high (5 V) without
connection. The polarity (high/ low) can be set via the software at the Master Unit (for
details please see the appropriate ION-U software manual).
The device to be monitored must be connected so that the alarm contacts will be
closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with
common ground (earth).
Subminiature circular connectors series 712 with eight contacts, which are included
in the alarm kit, can be ordered directly from the Binder Connector Group, the
manufacturer, or indirectly from CommScope.

6. Maintenance
6.1. General
Read the health and safety warnings in chapter 1.2.
Note: The remote unit does not require preventative maintenance
measures.
Note: To prevent malfunctions of the cooling system due to dirt or
pollution, it is recommended to clean the heat sink at regular
intervals. These cleaning intervals depend mainly on the location
of the remote unit and the corresponding degree of pollution.
Maintenance of the ION-U High Power RUs should be performed by replacing only
components that are described in this chapter. In order to maintain the warranty,
avoid unintentional damage to the seals on the modules.
The spare parts list, (see chapter 7.3) includes only units that can be replaced in the
field without tuning or soldering work.
Note: When sending back the unit, use appropriate packaging. Use of
the original packaging for shipping the unit is strongly
recommended!
Note: Defective parts should only be replaced by original parts from the
supplier. All service work performed inside the housing is
performed at the users own risk.
Note: Ensure the Remote Unit has been disconnected from mains power
during maintenance.
Note: Label any unlabelled cables before disconnecting them to ensure
correct reconnection.
For most maintenance procedures, appropriate tools are required to ensure correct
handling. All of these tools can be ordered from the supplier.
Note: All Remote Unit screws have a right-hand thread, and are
tightened by turning the screws clockwise and loosened by
turning them counter-clockwise with an appropriate tool.
Due to the design of the remote unit, the fan unit is the only component that should
be replaced in the field. Please contact the supplier for replacement of any other
components.
