operation. These numbers assume a mature design, good parts, and no
degradation of reliability due to manufacturing procedures and processes.
This fiberoptic laser transmitter contains a class IIIb laser product as defined
by the US Department of Health and Human Services, Public Health
Service, Food and Drug Administration This laser product complies with 21
CFR, Chapter I, Subchapter J of the DHEW standards under the Radiation
Control for Health and Safety Act of 1968. The laser module certification
label is located on the equipment enclosure and it also shows the required
DANGER warning logotype (as shown below).
The Ortel laser products are used in optical fiber communications systems
for radio frequency and microwave frequency analog fiberoptic links. In
normal operation, these systems are fully enclosed and fully shielded by the
hermetically sealed laser metal package. Laser bias current is limited by
the internal control circuitry. The transmitters are coupled to glass fiber and
have 1310 nm optical output wavelength with typically 0.5 to 20 mW output
depending on the model. The optical radiation is confined to the fiber core.
Under these conditions, there is no accessible laser emission and hence
no hazard to safety or health.
Since there is no human access to the laser output during system
operation, no special operator precautions are necessary when fiber is
connected to the transmitter and receiver. During installation, service, or
maintenance, the service technician is warned, however, to take
precautions which include not looking directly into the fiber connector
or the fiber which is connected to the fiber connector before it is
connected to the fiberoptic receiver. The light emitted from the
fiberoptic connector or any fiber connected to the connector is
invisible and may be harmful to the human eye. Use either an optical
power meter or an infrared viewer or fluorescent screen for optical
output verification. All handling precautions as outlined by the FDA
and ANSI 2136.2 and other authorities of class IlIb lasers must be
observed.
Do not attempt to modify or to service this Product. Contact the Ortel
Corporation Customer Service Department for a return authorization if
service or repair is necessary.

CHAPTER 1 INTRODUCTION AND APPLICATION
OUTLINE OF MANUAL
This manual describes the Ortel MirrorCelI Series 5800 In-Building Fiberoptic RF
Distributed Antenna System, provides the product specifications, and describes the
methods used to measure the system performance The first chapter describes the in-
building application of the MirrorCeIl Series 5800 system. The second chapter describes
the system, the components and features. The third chapter gives the specifications for
the overall system and for each line replaceable component in the system. Chapter 4
describes how to measure the performance of the system.
The first section of this manual provides information for engineering design purposes.
Installation, maintenance and troubleshooting can be found in Chapters 5, 6, and 7.
APPLICATION
The Ortel MirrorCeIl Series 5800 system can be used in a building to send radio signals
over optical fiber to many different locations such as an office area, a conference room or
a lobby. The signal is fed to local antennas at each location. By distributing the RF signal
to many antennas located throughout the building, a fiberoptic distributed antenna system
can provide uniform coverage throughout the building
The fibers typically emanate from a source point (small base station) in the building.
These fibers run from that source point, piping the signal to many fiberoptic antennas
throughout the building as shown in Figure 1-1.
One of the key advantages of a fiberoptic RF distribution system is that it separates the
issues of coverage and capacity. In an alternative system that covers a building by
distributing radio base stations, one must add a base station in that area when faced with
the problem of poor coverage in one section. Thus, capacity is added to a section which
might not need it. Similarly, when faced with a capacity problem in a portion of the
building, one would need an additional base station regardless of whether additional
coverage is required. Coverage and capacity are two separate problems. VWth a
fiberoptic RF distribution system, there are separate solutions to the two separate
problems. For poor coverage, an additional fiberoptic antenna is added; for an area with
insufficient capacity, more base station transceivers are added. In this way, equipment
and channels are most efficiently used, and the entire system is more economical. Not

only can the fiberoptic RF distribution system be used to create uniform coverage
throughout the entire building, including stairwells, elevator shafts and garages,
regardless of the size and construction, but it enables centralization of the equipment. In
the fiberoptic RF distribution system, the bulky equipment (such as the base station
transceivers, filters, and power supplies) are located in an equipment room, while the
antennas are strategically placed for coverage This factor is especially significant in
buildings where aesthetics are key, since it is easier to conceal a small fiberoptic antenna
than several radios.
The ability to centrally locate the PBX with base stations (voice and CDPD) is critical to
economically offering combined wireless office services such as cellular wireless PBX
and CDPD applications within the building. Centralized equipment has many advantages,
including serviceability and adaptability to new standards (such as digital cellular). These
advantages are especially apparent when the RF distribution system is shared by multiple
services like cellular voice and CDPD, Since the fiberoptic antennas cover the entire
cellular band and are format independent, they are capable of sending any type of signal
throughout the building, whether analog, digital or CDPD, and they can send them all
simultaneously Because the capacity is determined by the base station equipment, not
the antennas, once a building is wired for RF distribution via fiberoptics, capacity and new
services can be added without any changes visible to the customer

CHAPTER 2 SYSTEM DESCRIPTION
SYSTEM COMPONENTS
The MirrorCeIl Series 5800 In-Building Distributed Antenna System is a Fiberoptic RF
Distribution system designed to provide cellular coverage throughout a building or
campus of buildings The Fiberoptic System uses small Fiberoptic Antennas that are
similar in size to conventional smoke detectors and are typically mounted to a ceiling to
provide coverage to a sector of the building. These antennas are connected by optical
fibers to an RF Distribution Hub, which provides the interface to the cellular system
through connection to either a base station or a repeater. The Fiberoptic Antennas,
placed strategically throughout the building, create uniform coverage. Because the
attenuation of fiber is negligible, the Hub and cellular equipment can be located anywhere
in the building without concern for the distance between the Hub and the Fiberoptic
Antennas.
The MirrorCell Series 5800 consists of an RF Distribution Hub and up to 16 Fiberoptic
Antenna units. As shown in Figure 2-1, at the Hub, the MirrorCelI Series 5800 interfaces
with the Cellular System (a base station or a repeater) and converts the cellular signals to
or from optical signals. At the Antenna units, the MirrorCell Series 5800 converts the
optical signals to and from cellular signals for interface with the mobile user. Optical fiber
cables connect the Hub to the Antenna units. The system provides bi-directional signal
transmission between the Hub and the Antenna units via fiberoptics. The downlink signal
is the path from the Hub to the Antenna units. The downlink cellular signal enters the Hub
and is split to several Fiberoptic Transceivers that convert the RF signal to an optical
signal. The signal is sent along optical fiber to the Fiberoptic Antennas, where the
Antenna unit‘s photodiode converts it to RF again The RF signal is then amplified and fed
to the Antenna for transmission. The uplink path is the signal from the Antenna units to
the Hub. The uplink signal is received at the Antenna and amplified before the Antenna
unit‘s laser diode converts the signal to an optical signal for transmission to the Hub. At
the Hub, the optical signal is converted to RF and combined with the signals from other
Fiberoptic Antennas. In this way, all Fiberoptic Antennas that are served from a Power
Splitter/Combiner pair appear to the Base Station as one Antenna. It is also possible to
have multiple splitter/combiner pairs and configure a building as multiple cells.
The optical fiber cable that links the Hub to the Antenna units can be as long as 2 km to
provide the user flexible placement of the Antenna units for optimum coverage and
capacity handling. Any optical connector inserted in the MirrorCell Series 5800 (such as
through a patch panel) must have an optical return loss greater than 55 dB (for example
2-1
onei Corporation
MirrorCell® Series 5300 for AMPS/GSM Applications Fiberootic RF
tight fit FC/APC optical connectors). Othen/vise optical reflections can degrade overall
system performance. The total optical reflection back to the laser module must be less
than -40 dB. The cable can also contain two wires to supply power from the Hub to the
Antenna units, For 18 AWG copper wire, the maximum length is 45 m. Other user
requirements are given in Chapter 3.

For verification of system functionality, there are alarm outputs located at the rear panel of
the chassis (Figure 2-5) and LED indicators at both the Transceiver plug-ins and the
Antenna unitsc At the Antenna unit, the LED indicates whether optical power is being
received for the downlink path as shown in Figure 24. In a Transceiver plug-in, there are
two LED’s, one for each of the two round trip signal paths for that plug-inc Each LED
indicates the continuity of an RF test tone for the entire path, sent from the Transceiver
plug—in (downlink signal) to the Antenna Unit and back to the Transceiver plug-in (uplink
signal). The status of each round trip path is monitored, and alarm outputs are available
at the chassis. A summary alarm will indicate a failure in any path. The DIP switch can be
used to prevent a signal path that isn't being used from tripping the alarm.
In addition to the built—in chassis power supply, inputs are provided so that the user can
hook up a redundant power supply to back up the primary built-in power supply or battery
The MirrorCeIl Series 5800 automatically switches to the backup power source in case
the primary supply fails. The primary power supply is monitored and alarm outputs are
available at the chassis Upon repair of the primary power supply, the system
automatically switches back to the built-in chassis power supply.

CHAPTER 3 SPECIFICATIONS
LINK SPECIFICATIONS
For specifying performance levels in Figure 3-1, each fiberoptic link is defined between
the Hub (N-Type connectors on the Power Splitter/Combiner plug-ins) and the antenna
connection on the Antenna unit. The link specifications are given in Figure 3-2. The user‘s
downlink cellular signal connects to the input of the MirrorCelI Series 5800 RF power
splitter, and the RF output is at the Antenna unit for broadcast. In the other direction, the
uplink signal from the mobile user is received by the MirrorCeIl Series 5800 RF Antenna
unit and transmitted to the Hub chassis The RF output from the Mirror XCelI Series 5800
uplink is at the RF power combiners at the Hub. The uplink signal is then received by the
Cellular System

The performance levels shown in Figure 3-2 are for an optical loss budget of 2 dB, which
is the typical optical path loss for 2 km optical fiber and a pair of optical connectors.
Optical reflection back to the laser must be low The total optical reflection back to the
laser module in the Transceiver plug-in or Antenna unit must be less than —40 dB.
Otherwise, the overall system performance may be degraded. Figure 3-3 shows
requirements that the user must satisfy for proper operation of the MirrorCelI Series 5800
system Figure 3-4 is a table which provides a guide for the user to set up his Downlink
signal levels. It gives the nominal RF power per channel that the user can provide to the

In reference to the DIP switch numbering scheme, the signal path and alarm designated
as "4-2" refers to the second signal path in the Transceiver plug-in in Slot T4. The chassis
alarm connector provides open collector alarm outputs for each of the 16 signal paths
from 1-1 to 8-2. A summary alarm output is provided which sums all the transceiver alarm
outputs together. If any transceiver has a failure, then the summary alarm will indicate
failure. The alarm enable/disable switch for any signal path that is not hooked up should
be turned "oft" in order not to activate the chassis summary alarm, indicating system
failure.
In reference to the alarm output connector, the primary power supply, the Transceiver
plug-ins and the chassis summary status are monitored and alarmed The alarm outputs
are open collector outputs such that under normal conditions, when there is no alarm,
there is no collector current flow and the output can withstand 15 V. When there is an
alarm, the open collector outputs are capable of sinking 20 mA. Figure 3-10 shows a
typical circuit which can monitor the alarm status by measuring the open collector voltage.
When there is no alarm, the monitor voltage is 15 V; when there is an alarm, the monitor
voltage is 0 V. The open collector outputs can also be wired to drive relays for Form C-
contact closure switches

Each Model 5821A/B/C Transceiver plug-in provides bi—directional signal transmission
(uplink and downlink) between the Hub and two Antenna units. The major components in
the Transceiver plug-in are shown in Figure 3-11. For the downlink path, the Transceiver
plug-in contains two laser modules to feed two Antenna units. An RF test tone to
determine system continuity is sent from the Transceiver plug-in along the Downlink
Cellular signals. The Transceiver plug~in also contains two photodiode modules to receive
the uplink signals from the two Antenna units. The RF test tones originally sent along the
downlink and received by these two photodiodes in the return path are monitored and

GAINz FLATNESS, GAIN VARIATION
These measurements are made using a network analyzer as shown in Figure 4-2. After
calibrating the network analyzer with the necessary RF cables, connect Port 1 of the
network analyzer to the RF input to the MirrorCell Series 5800 and Port 2 to the RF
output. For the Downlink, the RF input is at the N-Connector of the front panel of the RF
Power Splitter plug-in and the output is at the Antenna Unit RF connector (excluding the
Antenna itself). For the uplink, the RF input is at the Antenna unit RF connector
(excluding the Antenna unit itself) and the RF output is at the N-Connector of the RF
Power Combiner plug-in front panel. The $2, measurement parameter provides gain and
flatness over the frequency bandwidth of interest. The gain variation with temperature can
be measured by inserting the units in an oven and measuring the change in the system
gain as the temperature is varied.

INPUT/OUTPUT VSWR
These measurements are made using a network analyzer. Set up the measurement as
described above for measuring amplitude response (gain). The 811 and $22 measurement
parameters provide the input and output return loss of the fiberoptic link. This can then be
translated to input/output VSWR. A VSWR of 1.5:1 corresponds to a 14 dB return loss.
PROPAGATION DELAY
These measurements are made using a vector network analyzer. Set up the
measurement as described above for measuring amplitude response (gain). The delay
measurement function gives the propagation delay as a function of frequency. The fiber
spool must be removed for measuring the propagation delay of just the RF portion.
The typical time delay for fiber is 5 ms/km, given by:
T = n/c = 1.5/(0.3 km/ms)
where n is the refractive index of glass and c is the speed of light.
OUTPUT CARRIER TO NOISE
To measure the output carrier to noise, one needs a signal generator that puts out a
clean tone at the frequency of interest. Measure the output of the signal generator with a
power meter and adjust the signal source to the appropriate output level. Ensure that the
signal level does not exceed the maximum RF input level rated for the units to be tested.
The Carrier to Noise (CNR) of the signal generator should also be measured to ensure
that it is not limiting the measurement.
Then connect the signal generator to the input of the Fiberoptic (F0) system to be tested
and an RF spectrum analyzer to the RF output as shown in Figure 4-3. For the Downlink,
the RF input is at the front panel of the RF Power Splitter plug—in and the output is at the
Antenna Unit RF connector (excluding the Antenna itself). For the uplink, the RF input is
at the Antenna unit RF connector (excluding the Antenna unit itself) and the RF output is
at the RF Power Combiner plug-in front panel.
Set the spectrum analyzer to the center frequency of interest. Measure the signal level.
Then measure the noise by setting the A'I'I'EN to 0 dB so that the noise contribution from
the spectrum analyzer is minimum. Activate the noise density measurement and the
marker to measure the noise level in dBm/Hz. If the spectrum analyzer does not have a
noise density measurement feature, then the user must determine the output noise level
4-4
Oriel Corporation
MirrorCeII® Series 5800 AMPS/GSM Applications, Fiberoptic RF
from the spectrum analyzer resolution bandwidth (BW). The CNR in a 1 Hz BW is the
difference between the signal level and the noise level. Calculate the output CNR in a 30
kHz BW:
CNR(30 kHz) = CNR (1 Hz) - 44.8 dB
The noise contribution from the spectrum analyzer should be measured to ensure that it
below that of the fiberoptic system. This is simply done by measuring the spectrum
analyzer noise floor when it is terminated into a matched load (usually 50W) if the noise
level is the same without as it is with the fiberoptic system, then it is necessary to add a
post-amplifier after the fiberoptic link to enable measurement above the spectrum
analyzer noise floori

LINEARITY - TWO CARRIERS
For this test, the measurement setup is shown in Figure 4-4. A two-tone signal generator
is connected to the RF input to the fiberoptic system. The two-tone signal generator must
provide two clean tones. The ratio of the carrier to third order distortion of the signal
generator should be >70 dBc for 0 dBm RF output tones in order to negligibly affect the
measurements. The RF output from the fiberoptic link may need to be filtered before
inputting to a spectrum analyzer to prevent distortion contributions from the spectrum
analyzer.
Vtfith an RF filter, the filter first needs to be adjusted to allow the carrier (tone) signal to be
measured by the spectrum analyzer. Then, the filter should be adjusted to remove the
two tones while allowing passage of the third order intermodulation distortion product. The
frequency of the third order intermodulation product is at 2f1 1 f2, where f, and f2 are the
frequencies of the two tones. The third order intermodulation distortion can now be
measured by the spectrum analyzer and compared to the carrier. The linearity
performance is given by the amount the third intermodulation product is below the carrier:
(C/I) in units dB.
From the Oil, one can then compute the input third order intercept (IIP3). The input lIP3 is
given by:
IIP3 = RF + (1/2)(C/l) dBm,
input
where RFInput is the power per tone in units dBm and C/I is in units dB.

using the table in Figure 6-34 Each chassis can hold a total of 8 Transceiver plug-
ins in Slots T1 through T8, starting from the left-hand side of the chassis, following
the two RF Power Splitter plug-in slots (see Figure 6-4). Slot T1 is the third single
wide (1 .4 inch wide) slot from the left—hand edge of the chassis. Each Transceiver
plug-in distributes signals to and from two separate Antenna units Hence, the
signal paths are identified as follows: T3-2 corresponds to signal #2 from the
Transceiver plug—in in Slot T3 The table associates each signal path with a
specific Transceiver plug-in (by serial number and its position in the chassis) and
with a specific Antenna unit (by serial number and its location in the building) The
table also documents the location of the DC power source for each Antenna unit,
Each chassis can provide DC power for as many as 6 remote Antenna units

After documenting the system layout using the table in Figure 6-3, gently insert the
plug-ins into the chassis along the guide rails. Blind-mate RF connectors interface the
plug—ins to the chassis backplane.
The RF connections at the rear of the chassis have been wired at the factory. Notice
at the rear panel of the chassis that the RF connectors at the RF Power
Splitter/Combiner plug-ins are numbered from 1 to 8 (Figure 6-6). These numbers are
associated with the Transceiver plug-ins from 1 to 8. For example, the RF output #3
of a Power Splitter plug-in is connected to the RF input of the Transceiver in slot T3.
Similarly, the RF output of the Transceiver in T3 is connected to the RF input #3 of the
Power Combiner plug-in. All the RF connections at the chassis rear panel have been
made at the factory, and all chassis slots are available for use.

1. The Antenna unit must be mounted in a suitable location to maintain the operating
environmental temperature of 5 to 40°C.
2. First, use the mounting flange as a template to cut the proper openings in the
ceiling tile for the mounting screws and for the optical and electrical wires. Verify
that the optical and electrical wires are labeled. Then pull the appropriate optical
and electrical wires out from the ceiling.
3. Attach the mounting flange to the ceiling at the four corners. As shown in Figure 6-
7, there are four #8 clearance holes at the corners of the flange for mounting to the
ceiling. Use the necessary hardware (nuts, bolts, lock washers, screws, anchors,
etc.) to ensure a secure attachment to the specific ceiling.
4. Next, check that the Antenna unit is assembled with an Antenna. The RF port (a
user specified option) on the Antenna unit can be used for attaching the user‘s
own antenna and for RF testing.
5. Optical and electrical connections can now be made before mounting the Antenna
unit to the flange. The optical and electrical cable should already be accessible to
the Antenna unit through the hole in the ceiling. Optical connections will now be
made to the Antenna unit. The optical connectors used in this system are the
standard FCIAPC connectors for 1310 nm singlemode fiber which specify a return
loss of >55 dB, For optimum performance, the tips of the optical connectors
must be cleaned just prior to making the connection. To clean the connector,
gently wipe the tip of the ferrule with a cotton swab moistened with alcohol, then
blow the ferrule dry using dust-free compressed air. The optical connections to the
Antenna unit can now be made. The optical connectors should all have been
labeled to indicate the specific connection: which Antenna unit and whether it is
an optical input or output.
6. DC electrical connections can be made through the terminal block on the Antenna
unit, using customer supplied Iugnuts for a #6 screw (0.138“ dia.). The polarity of the
DC power for the Antenna unit is labeled on the Antenna unit. Ensure that the DC
polanty supplied to the Antenna unit is correct. To attach the ceiling electrical wires
that are from the DC power source, strip away approximately 0.4 inch of the insulation
from the electrical wires. Ensure that the wiring is correct before connecting to the
Antenna unit.

HUB INSTALLATION
The Hub consists of a chassis with a built-in power supply, Transceiver plug-ins, RF
Power Splitter and RF Power Combiner plug-inst Figure 6-4 shows an example of a
populated chassis.
Put the chassis in a suitable location to maintain the operating environmental
temperature (5° to 40°C). The MirrorCeIl Series 5800 Hub can be mounted in a
standard 19 inch rack using four screws and guide rails. Each chassis must have
1U (1.75 inches) of air space above and below it for thermal dissipation.
Ensure that the appropriate AC power source is supplied to the chassis. Plug the
chassis power plug into a source of AC power. The MirrorCeIl Series 5800 unit is
now powered "ON".
Optical connections will now be made to the FO Transceiver plug-ins. The optical
connectors used in this system are the standard FCIAPC connectors for 1310 nm
singlemode fiber which specify a return loss of >55 dB. For optimum
performance, the tips of the optical connectors must be cleaned just prior to
making the connection. To clean the connector, gently wipe the tip of the ferrule
with a cotton swab moistened with alcohol, then blow the ferrule dry using dust-
free compressed airl The optical connections to the Transceiver plug-ins can now
be made. The optical connectors should all have been labeled to indicate the
specific Antenna that it is being connected to.
Place a protective cap over any optical connector that is not being used. This is
essential since dirty or scratched connectors will impair future performance of
those signal paths
The system is now ready for RF connection Figure 6-9 gives the nominal RF
input levels that the user provides to the Downlink Fiberoptic System as a function
of the number of channels. Check the Downlink power levels and adjust according
to the table in Figure 6-9 before connecting to the Fiberoptic System. Connect the
downlink Cellular signal to the N-Connectors of the MirrorCeII Series 5800 RF
Power Splitter plug-ins located to the left of the chassis. Similarly, the uplink
Cellular signal from the Fiberoptic System is located at the N-Connectors of the RF
Power Combiner plug-ins, Connect these to the user's uplink cellular receiver

Connect the alarm monitoring outputs to the user‘s monitoring system. The
chassis rear panel connectors and pinouts are shown in Figure 6-10 The
MirrorCeII Series 5800 alarm outputs are open collector outputs such that under
normal conditions, when there is no alarm, there is no collector current and the
output can withstand 15 V. When there is an alarm condition, the open collector
outputs are capable of sinking 20 mA.
At the rear of the chassis, switch the DIP switches to the "ON" position for those
signal paths that are active If a switch is in the "OFF" position, then the summary
alarm output will not respond to a failure of the corresponding signal path.
If a standby power supply is available, connect it to the 2-pin Molex connector at
the chassis rear paneL The standby power supply should be capable of providing
12 VDC and 8.5 A for maximum loading Ensure that the polarity is correct to
avoid damaging the system.
