2 Functional Description

2. FUNCTIONAL DESCRIPTION

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 1540 nm - 1562 nm is used. For the DL, a wavelength of
1310 ±20 nm is used. The maximum output power for the UL and DL is 5.7 mW.

2.2. THE ION-M80/90/19P

The fibre-optic distribution system is designed for LMR and PCS services. Up to
three bands (LMR800, LMR900 and PCS1900) can be transmitted. Each fibre is able
to serve up to four Remote Units and to operate up to four providers. One Master
Unit can operate up to 124 Remote Units point-to-point plus 32 x 4 Remote Units in a
cascaded way.

An auto-levelling function for compensating different fibre losses and a
comprehensive supervision concept are implemented. Auto-levelling in DL works with
optical power measurement, in UL a 10.7 MHz signal is used for measuring the
optical loss. Thus a (“cascaded”) backbone structure can be used in the optical
network, i.e. up to four Remote Units can be connected to the Master Unit via only
one fibre and optical couplers.

The unit also provides a transparent link in the frequency range from 2496 MHz to
2690 MHz, which can be used e.g. for WiMAX applications in this frequency range.

The Remote Unit ION-M80/90/19P (Intelligent Optical Network; MMR) is connected
to a central Master Unit via optical-fibre lines. Specific customer designs for lamp
pole or wall mounting are available. Thus, the system provides many advantages in
view of easy site acquisition.

chapter 3.2.2 Connections. For mounting the cable connectors, it is recommended to
refer to the corresponding documentation of the connector manufacturer. The
bending radius of the antenna cables must remain within the given specifications.

For the selection of cable and antenna it should be considered that, 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 Andrew 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 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 into the connector. Attach and torque the
connectors properly.

3.4. OPTICAL-FIBER-CABLE CONNECTION - RULES

Main optical system parameters:

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 E2000APC8°

ION-M system:

The specified bending radius ( < 4 cm) of the optical fibers must not be

exceeded.

The pigtails for the connection between Master Unit and Remote Unit must

have a sufficient length. A protection for the feeding into units must be given.

The system attenuation of the optical fibers, including the connectors, must

not exceed 10 dB.

Page 23

User’s Manual for

Remote Unit ION™-M80/90/19P

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 (E2000APC8°) 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:

¾ Remove fiber-optic protective caps.
¾ Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause

cable damage and interrupt transmission.

¾ 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.

¾ Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.
¾ 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.

¾ 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.

Page 24 MF0133ABA.doc

3 Commissioning

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 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.

4.1. 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.

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 was an interruption of at least five
seconds after acknowledgement, a new alarm message will be generated.

4.3. ALARM STATUS

For details refer to the corresponding software documentation of the Master Unit.

4.4. STATUS LED ALARMS

For local supervision, a status LED on the connector flange of the remote unit gives

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.

The +28 V pin (for its location see figure 4-2 Flange connector, 7 poles) is protected
by a 500 mA thermoswitch. In case of exceeding this current between pin 7 and GND
and/or in case of a failure of the VSWR module, the thermoswitch turns into a high­resistive status. In this case no fuse needs to be replaced. Just wait a few minutes
until the thermoswitch reaches the normal operating temperature again.

) 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.

As accessory equipment the alarm kit (see chapter 6.3 Spare Parts) is available to
connect external devices to the external alarm inputs and outputs.

Page 35

User’s Manual for

Remote Unit ION™-M80/90/19P

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 according 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.

Subminiature circular connectors series 712 with five and seven contacts, which are
contained in the alarm kit (see chapter 6.3 Spare Parts) can be ordered directly from
the Binder Connector Group, the manufacturer, or indirectly from Andrew Solutions.

5 Maintenance

5. MAINTENANCE

5.1. 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-M80/90/19P should be performed by replacing only
components that are contained in this chapter. In order to maintain warranty, take
care not to damage unintentionally the seals on the modules.

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

) Note: Defect parts should only be replaced by original parts from the

supplier. All interventions inside the housing are at one’s own risk.

) Note: During maintenance ensure the Remote Unit has been

disconnected from mains.

) Note: Before disconnecting any cables, label any unlabelled cables to

ensure correct connection.

For most maintenance procedures appropriate tools are required to ensure correct
handling. All these tools can be ordered from the supplier. For screwing procedures
observe that all our screws have a right-hand thread, i.e. for fastening the screws
turn the tool clockwise and for unscrewing them turn it counter-clockwise.

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.
