all warning labels are kept in a legible condition. Replace any missing or
damaged labels.
8. Notice: Only license holders for the respective frequency range are allowed to
operate this unit.
9. Notice: Make sure the repeater settings are correct for the intended use (refer to
the manufacturer product information) and regulatory requirements are met. Do
not carry out any modifications or fit any spare parts, which are not sold or
recommended by the manufacturer.
1.4. Compliance
1. Notice: For installations which have to comply with European EN50385 exposure
compliance requirements, the following Power Density limits/guidelines (mW/cm²)
according to ICNIRP are valid:
o 0.2 for frequencies from 10 MHz to 400 MHz
o F (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
o 1 for frequencies from 2 GHz to 300 GHz
2. Notice: 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
4
cmmW
mW
cm
PD
P
D
where
P (mW) is the radiated power at the antenna, i.e. the max. rated repeater
output power in addition to the antenna gain minus the loss between the
repeater and the antenna.
PD (mW/cm²) is the allowed Power Density limit acc. to 47 CFR 1.1310 (B)
for general population / uncontrolled exposures which is
o F (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o 1 for frequencies from 1500MHz to 100,000MHz
RF exposure compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna co-location
requirements of 1.1307(b)(3).

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.
The ION-U system includes high power and low power Remote Units designed to
meet the specific requirements of a given DAS. An ION-U Master Unit can support
both high power and low power RUs simultaneously.
2.2. ION-U Low Power Remote Units
The ION-U Low Power Remote Units are scalable and integrated with up to:
5-band (Cell700, LMR800, Cell850, PCS1900, AWS-3 1700/2100) or
6-band with additional Extension Unit (WCS2300 MHz)
SISO capability. Two RUs can be operated as a pair for MIMO operation. These units
are compatible with analog, GSM, EDGE, IS-95, CDMA2000, EVDO, W-CDMA,
HSDPA, LTE and iDEN modulation standards. 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.

Mains Connector
The RU receives its power through the Mains connector . The type of connector is
dependent on the RU model. A 4-pin Amphenol connector is used for AC models and
standard DC models. A 7-pin Amphenol connector is used for DC models powered
by a dual cable supply.
Antenna Port
The RU has one duplex 4.3-10 (1-st generation RUs: N-female) antenna port for
transmitting and receiving signals to and from distributed antennas. This RF port can
be connected directly to an antenna (i.e. using RF jumper cables) or through splitters,
allowing additional antennas to be fed by the RU.
Probe
This port is used as measurement probe to antenna port.
Local Port RS-232
The RS-232 port is standard DB-9 female connector used for external modem
communication with an optional Extension Unit.
Status LED
The status LED provides a visual warning of an alarm condition. The color of the
LED indicates the severity of the alarm.
Pwr/Ctrl Connector
The Pwr/Ctrl connector supports an optional fan unit. The RU provides power and
fan speed control to the fan unit and receives alarms from it through this 7-pin Binder
connector.
Alarm Connector
The RU has two alarm relay inputs that can be used to monitor and report alarms
from external devices. The alarm connector is a 5-pin Binder connector.
Expansion Ports
The Expansion UL and Expansion DL ports are QMA female connectors that
are used to connect to a CommScope EU to provide additional bands.
Optical Ports
The LC-APC optical connectors are used to send and receive the signals between
the RU and the Master Unit’s OTRx modules.
The DL optical port receives downlink signals from the MU OTRx.
The UL optical port transmits uplink signals to the MU OTRx.

For the mains breaker, observe the following recommendation:
120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC service is
needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or
13 to 16 Amps for 240-Volt service.
For the DC power supply, observe the local regulations of the DC service provider.
Use the following method to install and connect the Mains power to the RU:
1. Locate the Mains power cable that was delivered with the RU.
2. Locate or install a suitable power junction box or receptacle near the unit and
route the power cable from the power source to the RU. Do not connect the
cable to the unit’s Mains connector at this time. The power source must be
interruptible.
3. The Mains cable must be properly secured observing local regulations and
electrical codes. Be sure to allow enough slack in the cable at the RU to plug
or unplug the cable into the Mains connector.

The selection of cable and antenna is an important consideration. Choose the type of
cable best suited for the antenna. Consider that a cable with higher loss is less
expensive but impairs performance.
Notice: Use an appropriate torque wrench for the coupling torques:
- for N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22mm (7/8) in
opening
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 unit.
Attention: To minimize passive inter-modulation (PIM) distortion, attention has to 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 or dirt into the connector.
Use protective caps for the connectors when not mounted.
Before mounting clean the connectors with dry compressed air.
Before mounting clean the mating surfaces of the connector with a lint-free
alcohol-drenched cloth on a wooden or non-metallic item.
Attach and torque the connectors properly.
Avoid metallic abrasion when mounting the connectors by only screwing the
connecting nut, but not turning the whole connector.
Use a torque wrench to fasten the connector, see above.
Clean the protective caps before mounting for antenna cable replacement.

Main optical system parameters:
Fiber:
Single mode fiber, type is 9.5/125 µm
Fiber-cable connectors LC/APC
ION-U system:
Note: The pigtails for the connection between Master Unit and Remote Unit
must have a sufficient length. Protection for the optical fibers must be
provided where the fibers feed into the units.
Note: The system attenuation of the optical fibers, including the connectors,
must not exceed 5 dB.
System attenuation and attenuation of optical components must be determined. This
can be achieved by measuring attenuation 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-System Installation:
Fiber-cable connectors have to be of the same type (LC/APC) as the connectors
used for the unit. The fiber-optic cables are connected to the optical transceiver.
Notice: 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 just before making the fiber connections.
Do not leave any LC/APC connectors open as they may attract dirt. Unused
optical connectors must always be covered by their caps.
Do not bend the fiber-optic cable in a tight radius (< 5 cm) as this may cause
damage to the cable 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. Use a fiber end-face inspection tool to scan both, the class fiber
and its surrounding area.
Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.
Connect the fiber-optic cables by inserting the cable end into the laser
receptacle.
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.
Notice: Care should be taken when connecting and disconnecting fiber-optic cables -
use the connector housing to plug or unplug a fiber. Scratches and dust
significantly affect system performance and may permanently damage the
connector. Always use protective caps on fiber-optic connectors not in use.
Cleaning Procedure for Fiber-Optical Components:
Any contamination in the fiber connection results in additional optical transmission
loss which could cause whole system failure. It is thus recommended that every fiber
connector be inspected and cleaned prior to mating.
The goal is to eliminate any dust or contamination and to provide a clean
environment for the fiber-optic connection.

When you clean fiber components, always complete the following steps carefully:
Caution: Laser radiation. Risk of eye injury in operation. Do not stare into the beam;
do not view it directly or with optical instruments.
1. Turn off the ION-U system (laser sources) before you inspect fiber connectors.
2. Check the connectors or adapters with a fiberscope before cleaning.
3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning).
4. Inspect the connector.
5. If the connector is still dirty, repeat the dry cleaning technique.
6. Inspect the connector.
7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning)
followed immediately with a dry clean in order to ensure no residue is left on
the surface.
8. Repeat steps 5 through 7 until surface is clean.
