2. Introduction

2. Introduction

2.1. 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 optical
loss must be less than 10 dB inclusive optical couplers or splitters.

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.

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.

2.2. The ION-M7P/17EHP

The ION-M7P/17EHP is a multi-band, multi-operator remote unit configuration used
in conjunction with a Master Unit in the ION optical distribution system. By supporting
the entire AWS-3 spectrum, faster and more reliable wireless service is ensured and
network quality can be improved.

This system transports up to two frequency bands simultaneously (700 MHz and
1700/2100 MHz), providing a cost-effective solution for distributing capacity from one
or more base stations.

The ION system transports signals on the RF layer in a very cost-effective manner
enabling multiple operators to use multiple technologies and move their signals
simultaneously from a cluster of base station to a number of remote locations over
the same fiber.

The ION-M optical distribution system is a cost-effective coverage solution for dense
urban areas, tunnels, subways, airports, convention centers, high-rise buildings and
other locations where physical structures increase path loss.

Page 12 MF0150A3A.doc Manual for ION-M7P/17EHP

3. Functional Description

The combination of these units gives maximum flexibility while providing a scalable
solution. The system is optimized for LTE, WCDMA, and CDMA signals in the 700
MHz and 1700/2100 MHz bands. Furthermore it is provisioned for future modulation
schemes and frequency bands.

The ION can be easily set-up and supervised from a graphical user interface (GUI).
Remote units are commissioned through the use of built-in test equipment. An auto
levelling function compensates for the optical link loss making installation easy and
quick.

The entire system as well as complete network of systems can be managed remotely
most efficiently by Commscope`s A.I.M.O.S, which includes alarm monitoring, task
automation, statistics, inventory management and many more features. Should a
sophisticated interface not be required, the master unit can be directly connected to
the alarm interface of a base station via its contact relay.

is adequate manpower to handle the weight of the system.

2. Caution: Risk of serious personal injury by equipment falling due to improper

installation. The installer must verify that the supporting surface will safely
support the combined load of the electronic equipment and all attached hardware
and components. The screws and dowels (wall anchors) used should also be

appropriate for the structure of the supporting wall.

4.1.2. Property Damage Warnings for Mechanical Installation

1. Attention: Do not install the unit in a way or at a place where the specifications

outlined in the Environmental and Safety Specifications leaflet of the supplier are

not met.

2. Attention: Due to power dissipation, the Remote Unit may reach a very high
temperature. Ensure sufficient airflow for ventilation.

3. Notice: Exceeding the specified load limits may cause the loss of warranty.

4. Notice: When connecting and mounting the cables (RF, optical, mains, ...)
ensure that no water can penetrate into the unit through these cables.

5. Notice: Also observe all additional rules or restrictions regarding mounting that

depend on the type of Remote Unit. For details refer to section 7.2.2 Mechanical
Specification. Install the unit vertically with the fan unit at the top. A maximum tilt

angle of 25° from a vertical position must be kept, as in the following illustrations:

relating to work on high voltage installations, as well as regulations
covering correct use of tools and personal protective equipment.

4.2.2. Property Damage Warnings for Electrical Installation

1. Attention: It is compulsory to ground (earth) the unit before connecting the

power supply. Grounding bolts are provided on the cabinet to connect the
ground-bonding cable.

2. Attention: If the mains connector of the Remote Unit is not easily accessible, a

disconnect device in the mains power circuit must be provided within easy reach.

3. Attention: A connection of the mains supply to a power socket requires the

power socket to be nearby the Remote Unit.

4. Attention: Before connecting or disconnecting the mains connector at the

Remote Unit, ensure that mains power supply is disconnected.

5. Attention: Make sure that an appropriate circuit breaker acting as a disconnect

device (as required by IEC/EN60950-1) and an overcurrent limiting device are
connected between mains power and the Remote Unit.

6. Attention: Incorrectly wired connections can destroy electrical and electronic
components.

7. Notice: To avoid corrosion at the connectors caused by electrochemical

processes, the material of the cable connectors must not cause a higher potential
difference than 0.6 V (see electrochemical contact series).

8. 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 7/16 DIN-type (25 N-m / 19 ft lb) with 1 ¼ in opening,
e. g. item no. 244377 available from the CommScope e-catalog

4.2.8. Optical-Fiber-Cable Connection - Rules

Main optica l system parame ters:

Fiber:

 Single mode fiber, type is E9/125 µm
 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
 Fibre-cable connectors E2000 APC 8°

ION-M 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 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.

MF0150A3A.doc Manual for ION-M7P/17EHP Page 27

Fiber-System Installation:

Fiber-cable connectors have to be of the same type (E2000 APC 8°) as the
connectors used for the unit. The fiber-optic cables are connected to the optical
transceiver.

4. Commissioning

 Note: 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. 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 and aligning the key (on the cable end) with the keyed slot.

 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 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:

Caution: Laser radiation. Risk of eye injury in operation. Do not stare into the

beam; do not view it directly or with optical instruments.

Any impurity 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.

When you clean fiber components, always complete the following steps carefully:

1. Turn off the ION system (laser sources) before you inspect fiber connectors.

2. Check the connectors or adapters with a fiberscope before cleaning.

Page 28 MF0150A3A.doc Manual for ION-M7P/17EHP

4. Commissioning

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 end face.

8. Repeat steps 5 through 7 until end face is clean.

modules to maintain warranty. Please keep these guidelines in mind during
maintenance:

Unless otherwise agreed to in writing by CommScope, CommScope’s general limited
product warranty (http://www.commscope.com/Resources/Warranties/) shall be the
warranty governing the Remote Units, including the installation, maintenance, usage
and operation of the Remote Units.

The spare parts list, consequently, contains only units which can be replaced without
tuning or soldering work.

 Note: Ensure the Remote Unit has been disconnected from mains power

during maintenance.

 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: 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 counter­clockwise with an appropriate tool.

Due to the design of the Remote Unit the only component recommended to be
replaced is the fan unit. For replacing any other component, please contact the
supplier.
