1. Introduction
1.1
Fiber Fed Repeater
The JF-46 FFR provides a cost effective solution for cell coverage extension and
increased call quality in shadow areas. It is a RF signal transport system that
provides long range RF coverage where it is impractical to install a BTS.
The JF-46 FFR is designed to be strategically placed to overcome difficult zoning
issues by allowing the base stations to remain at a central location while placing
antennas at remote locations. RF signals can be transported to remote locations to
expand coverage into areas not receiving service or to extend coverage into difficult
to reach areas such as canyons, tunnels and underground parking lots and roadways.
The JF-46 FFR provides a high-tech, highly-efficient service system which enables
high quality communication at low cost, due to the system’s utilization of one optical
fiber core between the DHU and RU supporting full duplex transmission of signals for
both the DL and UL.

1.2
Search Window
The purpose of using a repeater is to extend the coverage of the BTS by retransmitting the BTS signals to mobile stations in a non BTS coverage area. This
means that the BTS handles all kinds of call processing including calls being received
via the repeater. There may be a negative impact of service on the BTS if the
interface between BTS and repeater does not operate properly.
There would be an increase in time delay with calls received from the repeater,
compared to a call from its BTS coverage. Thus the additional delay introduced from
calls via the repeater must be considered while setting BTS parameters.
Window-size is the time range of the BTS traffic channel to search for the signal
originating from the MS. If the delayed signal is out of window-size, the BTS cannot
acquire the signal, which will result in dropped calls due to chip-delay.
Table 1.2.1 describes the two parameters used for controlling the window length, to
prevent the deterioration of call quality caused by chip delay. It is required to search
the signal properly by adjusting the two parameters.
Acquisitioin_Window_Length is adjusted to change the window size used to
search/monitor the neighboring PN and allow soft handoff while traveling to the
neighboring BTS where new traffic channels will be allocated to the MS.
Demodulation_Window_Length is adjusted to change the window size which searches
for the Rx signals. This parameter should be adjusted when the delay (with no change
of traffic channel) between transmission and reception is increased i.e. MS in repeater
service area.

signal. It should be set up with proper values considering time delay.
[Table1.2.1] Two Parameters for Search Window Setup
Therefore, the two parameters stated can be used to adjust the interface between
the BTS and the repeater considering the movement of the MS. Picture 1 shows an
example of two window size parameters for the JF-46 repeater application.
[FIGURE 1.2.1] HANDOFF BETWEEN BTS AND REPEATER
The Demodulation_Window_Length is used to adjust the time sync to compensate
the chip delay introduced by the optic core when the MS moves into the repeater
coverage area.
When the MS travels from the repeater coverage to the BTS B area,
Acquisition_Window_Length is used to adjust this time offset differences. With this
adjustment, the MS will be able to perform soft handoff from BTS A traffic channel
(while in repeater coverage) to the BTS B traffic channel.
Without these adjustments, there may have been two call drops while the MS traveled
from BTS A to BTS B.

1.3
Total Optical Delay (Window Size)
With the adjustments described above, good call quality should be maintained without
call drops. This section will show how to calculate the total delay and how the
parameters should be set up in the BTS. The equation below is an example of total
delay for an optic repeater.
SD(μsec) + OD(km) + RD(μsec) + RR(km)
SD : BTS System Delay (Time delay between antenna input port and demodulator in BTS)
OD : Optic Distance between BTS and repeater.
RD : Repeater System Delay
RR : Repeater Coverage Radius
* 1 chip = around 244 m
The total chip delay of 2km of RR and 5km of OD is as below.
36chip + 5000m(20.63chip) + 5 μ sec(6.6chip) + 2000m(8.25chip) = 71.45 chips (Approx.
72chips)
Based on the calculation of total chip delay, the two parameters should be adjusted for
good call quality when installing a new repeater. 71.45 chip delay corresponds to 12
(set value) Search window size (Size = 160 chips). Therefore, the
demodulation_window_length of BTS A should be set up as 12 in this configuration
and acquisition_window_length of BTS A and BTS B should also be set up as 12.
The table below shows the Search window size values for different optic distances
and repeater coverage.

General Safety Precautions
This equipment contains components that emit laser radiation which can
seriously damage the retina of the eye. Do not look into the ends of any
optical fiber. Do not look directly into the optical transceiver of any digital unit
or exposure to laser radiation may result. An optical power meter or
reflectometer should be used to verify active fibers. Place a protective cap or
lid immediately over any radiating transceiver or optical fiber connector to
avoid potential damage caused by radiation exposure. This practice also
prevents dirt particles entering the openings.
The optical fiber emits radiation. Do not look directly into the ends of an
optical fiber. This may result in exposure to radiation. Do not assume laser
power is turned off or the fiber is disconnected at the other end.
Wet locations and conditions will increase the risk of electrical shock when
installing or using electrical powered equipment. To prevent electrical shock,
never install or use electrical equipment in wet locations or during lightning
storms.
The DHU is powered by 115-230 VAC. To prevent electrical shock when
installing or maintaining the DHU, disconnect the wiring at the power source
before working with un-insulated wires or terminals.
The RU is typically powered by 115-230 VAC. To prevent electrical shock
when installing or maintaining the RU, disconnect the wiring at the power
source before working with un-insulated wires or terminals.
Always consider and allow sufficient fiber length to permit routing or patch
cords and pigtails without severe bends. Fiber optic patch cords or pigtails
may be permanently damaged if bent or curved to a radius of less than 2
inches (50mm).

2. System Description
2.1
FFR System
The JF-46 FFR is made up of a main Donor Hub Unit (DHU) and a RU. The DHU and
RU are divided into modules to allow easy operation and maintenance. It can operate
even in the harshest environmental conditions due to its durable IP55-rated
weatherproof enclosure.
[FIGURE 2.1.1] SYSTEM BLOCK DIAGRAM
2.2
Simulcast Operation
Please refer to Figure 2.2.1 for a system block diagram of a Simulcast FFR
configuration, where a single BTS sector provides coverage to two Remote Units. This
configuration employs two RF Splitter/Combiner units at the RF ports of the Donor
Hub Unit which relate to the two Remote Units.
On the DL path, the BTS signal is split two ways and feeds two DHU input ports.
Similarly, on the UL path, the signals from two DHU RF ports are summed and fed to
one port of the BTS.
19
Revision 0.01
Juni America Inc.
JUNI JF-46-E1900/CFN03
CDMA FIBER FED REPEATER OPERATIONS MANUAL
JUNI AMERICA PROPRIETARY & CONFIDENTIAL
The JF-46 FFR has adequate RF gain margin to support a Splitter/Combiner as
shown with loss of up to 10 dB. As a result, a single BTS sector can easily feed 4 or
even 8 Remote Units. If more than 4 Remote Units are to be supported, more than
one DHU is required since a DHU can support only a maximum of 4 Optic Modules,
which drive 4 Remote Units.

2.3.2 Wireless Modem Antenna
The technical requirements for the Wireless Modem Antenna are dependent on the
specific DHU location and network coverage. If the nearest BTS with a local antenna
is nearby the DHU, a 3 dBi Gain Omni antenna should be quite adequate. The
Modem Antenna is to be connected to the modem antenna connector on the DHU.
In the event the nearest BTS with a local antenna is quite some distance from the
DHU, a directional antenna with 10 dBi Gain, aimed at the nearest BTS with the local
antenna, is the appropriate modem antenna solution.

1. Verify that the power is switched OFF.
2. Before any other connections are made, ensure that the ground terminal on the RU
cabinet has been connected to the common ground of the installation site, as
described in the previous section.
3. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is 115 or
230VAC.
4. Check that the AC power cable is earthed and is supplying the correct voltage (115 or
230VAC) and polarity and then connect it to the AC input port of the RU.
5. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power
to the RU.
6. Verify that all electrical and optical connections have been completed and that all
optical fibers, coaxial cables and wires are properly routed and secured.

3.5.12 Operations Tests
This section provides test procedures for the uplink and downlink required to be
undertaken in order to set up the JF-46 for optimal service.
3.5.12.1 Optic Cable Loss Test
Connect the system as shown below:
[FIGURE 3.5.15] CONNECTION TO PERFORM OPTIC CABLE LOSS TEST
Check optic cable loss by using an optic power meter or reflectometer
1. With the DHU on, connect the power meter to the optic module of the RU and
measure the Forward (1510nm) output level. If the optic input level exceeds +7dBm,
check the DHU optic module.
2. If the optic loss is greater than –8dBo (on the basis of 1510nm, optic loss = donor
output optic power – remote input optic power) and the optic cable length between
the DHU and RU is less than 15 miles, check for faults in the PD (Photo Diode) or
check the optic cable.
3. If the optic loss is lesser than –2dBo (on the basis of 1510nm, optic loss = donor
output optic power – remote input optic power), add the optic jumper cable(2dBo).
4. If a PD fault has occurred, inspect the optic input level and check the optic line. Clean
the optic connector and if the fault is still existent, contact Juni technical support.
* Reference
Optic cable loss is 0.25dB/km at 1510nm, and connection loss is 0.4dB/connector. The total
optic loss due to the connector is about 1 to 2dB. (0.4dB ×2 (connector) = approx 1dB)

Introduction
The DHU utilizes a wireless CDMA modem connected to the SNMP agent to transmit
SNMP TRAPs and INFORMs to a central Sprint EMS (Element Management Server)
on the Sprint private network. The TRAPs, or commonly referred to as a heartbeat,
are sent at an interval of every 1 ~ 120 minutes and is a method of notifying the EMS
that the repeater is still connected to the network and is functioning correctly.
INFORMs are transmitted when an alarm at a RU occurs. The INFORM is sent to the
EMS providing information on the type of alarm that has occurred and the repeater it
originates from.

5. System Maintenance
This section explains the JF-46 FFR system fault detection and alarm reporting
system, and provides a method for determining troubleshooting faults.
Maintenance also includes diagnosing and correcting service problems as they occur.
When an alarm is reported, it will be necessary to follow a systematic troubleshooting
procedure to determine the problem. Once the problem has been isolated, the
appropriate corrective measures must be taken to restore service. The only internal
components that can be replaced are the cooling fans, which are mounted in the DHU
and RU, and the optic module.
All other failed internal components will require Juni
engineers to replace and test the units.

The JF-46 FFR requires minimal regular maintenance to insure continuous and
optimal operation and performance. However, it is advised that the DHU and RU are
checked often. Components that require regular replacement, cleaning, or testing
include the DHU and RU fans and backup battery. The IP55 enclosure ensures that
the JF-46 FFR can withstand all environmental influences. The following two
procedures can also be followed when a fan fails and needs to be replaced.
5.1.1 Donor Unit Fan Maintenance
1. The fan is located above the DRCU and is labeled ‘Fan Control Unit’.
2. Unplug the 24V power cable feeding the Fan Control Unit.
3. Unscrew the two multi-turn fasteners on each side of the compartment.
4. Pull out the Fan Control Unit completely from its position.
5. One fan is used to cool the DHU which will require regular maintenance by
cleaning and/or dusting.
6. Once maintenance is complete, return the Fan Control Unit back into its space
and tighten the multi-turn fasteners.
7. Plug the power cable back into the Fan Control Unit.

5.1.2 Remote Unit Fan Maintenance
1. The fan compartment is located at the bottom of the RU.
2. Remove the fan power cable underneath the RU.
3. By turning the stud on the side, remove the cover and pull out the fan
compartment carefully. Do not pull on it too hard. It will cause a 24V power cable
to be jammed.
4. There are two fans in the compartment which is required to be cleaned and
checked regularly to ensure proper operation of the fan and allow the fan to
perform its duty in cooling the RU.
5. At the completion of the maintenance, return the fan compartment by sliding it
back into its designated placement.
5.2
Fault Detection and Alarm Reporting
The JF-46 FFR on board embedded software detects various unit and system faults
which generate either a Major or Minor alarm. A major alarm indicates that the
repeater has failed in a way that directly affects RF transport performance. When a
major alarm occurs, all RF functions are affected and will cause the system to be out
of service. A minor alarm means that the system performance is not affected, or in
some cases, that the performance may no longer be optimal. When a minor alarm
occurs, RF functions continue and the system remains in service.
The following means are used to report major and minor alarms.
•
DHU LED’s
•
Web GUI(Graphical User Interface)
The DHU front panel LED indicators show status and alarm information by displaying
various colors; green, red and off.
The Web GUI provides both a summary and detailed list of alarm information that
includes unit and module level faults, circuit faults, and measured value faults such
as voltages, RF power and temperature.

Appendix E. BTS Hotel Rack Installation
Procedure
The following procedure is a guide for installing JF-43B Donor Hub Unit on to the rack.
1. The 10.5 in. (6 RU) high Donor Hub Shelf (DHS) is a 19 inch rack mount unit,
supports up to 4 Remote Units and mounts to the front of a standard 19 inch rack.
2. The 1.75 in (1 RU) high 4-Way Splitter Panel supports up to 4 Remote Units and
mounts to the rear of the rack. This panel is placed above and to the rear of the
DHS. Nine RF cables are integral to the Donor RF Connector Panel assembly, and
are routed across the top of the DHS to RF connectors on the front panel of the
DHS.
3. There is no additional vertical rack space requirement for external duplexers and/or
external transmit combiners, since these functions are integral to each Donor Optic
Transceiver Module.
4. The 1RU vertical spacing provided by the 4-Way Splitter Panel facilitates airflow
above the DHS. There is no other vertical rack space requirement for airflow.
5. Therefore the total rack space height requirement (per 4 Remote Units) is 10.5 +
1.75 in. = 12.25 in. ('7RU).
6. Therefore, a total of 73.5 inches of vertical rack space is required for 6 ea. Donor
subsystems [DHS + 4-Way Splitter Panel].
7. Donor Hub Unit (Indoor Configuration) Dimensions: 19 in. rack Wide x 10.43 in.
High x. 15.7 in. Deep
8. 4-Way Splitter Panel Dimensions: 19 in. rack Wide x 1.7 in. High x 7 in. Deep.

Appendix F. Simulcast and Non-Simulcast
Operations
The JF-46 system can be configured and operated in either Simulcast or Non-Simulcast
mode.
In Simulcast Mode, one BTS sector feeds multiple Remote Units. Juni offers a Four-Way
Splitter for use where one BTS sector feeds up to four Remote Units. It is Juni Model
JJAX0100008. The Figure below shows the Four-Way Simulcast configuration. The Fourway Simulcast Connector Panel is intended to mount at the rear of a 19 inch EIA rack,
immediately above the associated Donor Hub Unit. RF cables are furnished which connect
from the front of the Connector Panel to the various RF connectors on the front of the Donor
Hub Unit. The RF connectors which face toward the BTS are recessed.

In Non-Simulcast mode, each Remote Unit is fed by one “dedicated BTS sector. The
advantage of this approach is higher capacity per Remote Unit, compared to Simulcast mode.
Juni offers a Non-Simulcast Connector Panel, Model Number JJAX0100006. The NonSimulcast Connector Panel is intended to mount at the rear of a 19 inch EIA rack,
immediately above the associated Donor Hub Unit. RF cables are furnished which connect
from the front of the Connector Panel to the various RF connectors on the front of the Donor
Hub Unit. The RF connectors which face toward the BTS are recessed.
