1.2. Health and Safety Warnings
1. Danger: Obey all general and regional installation and safety regulations relating
to work on high voltage installations, as well as regulations covering correct use
of tools and personal protective equipment.
2. Danger: Laser radiation! Do not stare into the beam; do not view it directly or with
optical instruments.
3. Danger: Before opening the unit, disconnect mains power.
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.

User’s Manual for ION-U 7/8/85/17/19
0 Introduction
Introduction
1.4. Purpose
Cellular telephone systems transmit signals in two directions between base
transceiver station (BTS) and mobile stations (MS) within the signal coverage area.
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 distribution system.
Such a system contains an optical Master Unit and several Remote Units. The
number of the Remote Units depends on the hardware and software configuration.
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 the remote units via optical fibers.
1.5. The ION-U L 7/8/85/17/19 Remote Unit
The ION-U 7/8/85/17/19 is a low power remote unit for Cell700, LMR800, Cell850,
AWS, and Extended PCS1900 Band Applications. The unit is compatible with analog,
GSM, EDGE, IS-95, CDMA2000, EVDO, W-CDMA, HSDPA, and LTE modulation
standards. It is used in conjunction with a Master Unit in the ION optical distribution
system. This system transports multiple signals simultaneously, providing a costeffective solution for distributing capacity from one or more base stations.
The ION-U 7/8/85/17/19 transports signals on the RF layer in a very inexpensive
manner. This means that multiple operators and multiple technologies are moved
simultaneously from a cluster of base stations to a remote location over the same
fiber.
The ION optical distribution system is a cost-effective coverage solution for dense
urban areas, tunnels, subway, airports, convention centers, high-rise buildings, and
other locations where physical structures increase path loss. It has been specifically
designed to reduce zoning problems and to provide homogeneous coverage and
capacity.
MF0147A0A
Page 15
0 Introduction
The ION-U L 7/8/85/17/19 is capable of supporting both SISO and MIMO. RF signals
are transported to the remote units via single mode fiber at 1310 nm. MIMO is
achieved with the use of 4 fibers and the pairing of two interlinking RUs.
The system includes an Automatic Gain Control (AGC) that avoids field adjustments
and reduces design, installation, and optimization time.
The ION is easily set-up and supervised via a graphical user interface (GUI). Remote
Units can be commissioned using built-in test equipment. Optical Loss is
compensated through the AGC. Autolevelling allows the output power to be levelled
as specified in the system configuration. The entire system may be monitored
remotely via an Andrew OMC. This platform uses SNMP protocol and is compliant to
X.733 standard.
Should a sophisticated interface not be required, the Master Unit can be directly
connected to the alarm interface of a base station via a LAN (local area network) or
its contact relay.

2 Functional Description
2. Functional Description
In the Downlink (DL) path, the remote unit provides:
 Optical to RF conversion of the input optical signal
 Automatic Gain Control (AGC) of each converted signal to compensate for

within the given specifications.
MF0147A0A
Page 31
3 Commissioning
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 for the coupling torque of N-type
connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type
antenna connectors. For example, use torque wrench of item no. 244379
available from the CommScope e-catalog. 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.
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.
1. Route the antenna cable from the antenna or splitter to the base of the RU.
2. Cut the cable to length and terminate the cable with an N-type male connector.

3.3. Optical-Fiber-Cable Connection - Rules
Main optical system parameters:
Fiber:
 Single mode fiber, type is 9.5/125 µm
 Fiber-cable connectors LC/APC
ION-U system:
 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.
 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 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-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.
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.
MF0147A0A
Page 35
3 Commissioning

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.
 Note:
Care should be taken when connecting and disconnecting fiberoptic 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:
1. Turn off the ION-U system (laser sources) before you inspect fiber connectors.
Never look into a fiber while the system lasers are on!
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 endface.
8. Repeat steps 5 through 7 until endface is clean.

4. Alarms
4.1. Bite and Alarms
The Built-In Test concept comprises the monitoring of the power supplies, the power
amplifiers, and the optical interface.
All alarms that occur can be checked via software at the master unit.
4.2. 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 is an interruption of at least five seconds
after acknowledgement, a new alarm message will be generated.

4.3. Status LED Alarms
For local supervision, a status LED on the connector panel of the remote unit
adjacent to the Expansion ports 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.

table 4-1 Status LED alarms
4.4. External Alarm Inputs
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 five contacts, which are contained
in the alarm kit, can be ordered directly from the Binder Connector Group, the
manufacturer, or indirectly from CommScope. For the designation of the alarm kit see
chapter 6.5 Spare Parts.

4.5. Troubleshooting
The status of the remote unit can be checked via the master unit (for details please
refer to the ION-U software manual). Locally, the status can be checked at the LED,
see chapter 4.3 Status LED Alarms.
