INTRODUCTION TO THE MODULITE™
2. Introduction to the ModuLite™
Infrastructure for multiple services is currently provided through two different methods. The first
method is a parallel infrastructure based on a fiber or hybrid fiber-copper solution. In this system,
even though all operators provide mutual services with a potential for sharing, a complete
infrastructure is deployed for every operator. Multiple antennas need to be installed in every
radiation zone. Isolation between antennas is hard to control, and as a result, cross antenna
interference may cause degraded performance.
The second available solution is based on coax. Coax has different attenuation levels for
different frequencies. This leads to design constraints because the coax needs to match the
highest frequencies serviced and their respective attenuation levels. This requirement leads to
higher costs resulting from the larger diameter coax and from a more labor-intensive installation.
Foxcom Wireless’s ModuLiteTM is a new approach. The ModuLite™ is a high-performance, cost
effective and modular In-Building system designed for multiple wireless services. It is
technically superior to other available infrastructures, and provides WSP’s and building
operators with an advanced platform for expansion and upgradability.
Figure 1: ModuLite™ System
The ModuLite™ has unique advantages:
• Low attenuation: Singlemode fiber optic cables have virtually no attenuation (0.38dB/Km),
relieving the need to install amplifiers or any other signal enhancing in-line devices. This factor
alone greatly reduces the engineering and installation costs.
Foxcom Wireless Confidential and Proprietary Information
Document No. 43-93-005-05 X1
ModuLite Installation Guide
INTRODUCTION TO THE MODULITE™
• Low noise: High bandwidth signals can be set over singlemode fibers without encountering
noise problems, and transmitted over great distances.
• Multi Services: Same infrastructure is used either supporting single service or multiple
services, due to the pseudo infinite bandwidth of singlemode fiber optic cable.
2.1. Applications
The ModuLite™ addresses both public and private markets in order to provide RF distribution
solutions for various structure types:
• Typical Public Market
o Malls
o Airports
o Conventions Centers
o Hospitals
• Typical Private Market
o Office Buildings
o Business Centers
o Campus
Three types of applications are very common for both markets:
• High Rise Buildings
• Horizontal Structures
• Campus type
Foxcom Wireless’ ModuLite™ addresses these application types with a powerful answer, while
still flexible and future expandable. There are no limitations for building height or structure
spread.

System Description
The ModuLiteTM is a new system for the provision of In-Building multiple wireless
services. Its high performance yet cost effective structure efficiently enables the addition
of new wireless services.
The ModuLiteTM is a hybrid fiber coax modular solution designed to serve multiple
wireless services using a single common cabling infrastructure. The cabling infrastructure
includes a fiber optic cable, a single coax cable, and a single antenna.
The ModuLiteTM has two main modules, the MBU (Modular Base Unit) and the MRC
(Modular Remote Cabinet). Both components are designed such that they can be located
in easily accessible area, such as the communication room, the communication closet, or
in the riser.

The MBU converts RF signals from the RF source (Base Stations/off- air repeater) to an optical signal
using direct modulation technology. Each BU module can support two to four services, depending on
the application. The MBU is connected viaFigure
a single
fiber optic
cable
to the MRC.

ModuLite™
Block
Diagram
The MRC is comprised of modular remote units, each supporting two to four services, yet each
modular remote unit has sub RF channels in order to maximize the performance of each specific
service in terms of IMD suppression and dynamic range. Each MRC can contain four modular remote
units, hence at least eight services. The RF modules can be added as required to support the required
services. The MRC converts the optical signal to RF, performs filtering and enhanced signaling via its
Remote Interface Module, and connects to a single antenna via a single coax cable.
The ModuLite’s TM main features are as follows:
· Single cabling and antenna system for all services
o enables fast deployment for WSP’s of new services
o reduces tenant disruption
o simplifies maintenance

INSTALLATION
4. Installation
The following sections describe the ModuLiteTM installation.
•
•
•
•
General Installation.
Fiber Installation.
Hi Rise Installation.
Horizontal Layout Installation.
4.1. General Installation
The ModuLite™ components need to be set up, followed by performance verification before
installing the system. Foxcom Wireless suggests that a 19” rack-mountable Splice Tray be used at
the Modular Base Unit to facilitate optical fiber splicing. In the rack, the Splice Tray is mounted
above or below the Modular Base Unit (depending on direction of the incoming cables).
The MBU and MRC units should be installed in a communication room that provides access
to authorized personnel only. The units are maintenance free. In the event of failure, only
authorized personnel should handle the units.
Set up procedures for the Modular Base Unit (MBU) and Modular Remote Cabinets (MRC) are for
the following installations:
• High-rise installations.
• Horizontal layout installation.
For both installations, setting up the Modular Base Unit and Modular Remote Cabinets consists of
the following steps:
1.
Determine antenna placement by system engineer: When an area needs RF cellular
augmentation, a RF engineer needs to determine the type and the location for each antenna. The RF
engineer should consider all relevant RF parameters (RF propagation models, isolation between
antennas in accordance with the appropriate standard, and environmental conditions) as well as
landlord limitations.
2.
Determine the amount of antennas required. This number, in turn, determines the number of
Modular Remote Cabinets to be used. The number of Modular Remote Cabinets has a direct
influence on the type and the number of fibers to be installed.
3.
Pull fiber optic cable and copper cables through building. Install fiber optic cable according to
the optic design (see Figure 17) Prepare 10% to 15% more fibers than are actually required. In order
to supply D.C power to the Modular Remote Cabinets remotely, copper cables need to be installed
in parallel to the fiber optic cable (see Figure 17).
23

ModuLite Installation Guide
INSTALLATION
4.
Install Modular Base Unit in 19” rack. The number of Modular Base Units depends on the
number of Modular Remote Cabinets. Each Modular Base Unit is installed with four screws on the
front panel (two on each side) connecting to the 19” rack.
5.
Install patch panel/splice tray cabinet with SC/APC adaptors in a 19” rack or wallmount
near Modular Base Units. All fibers are installed in the patch panel, in which the backside is the
fiber optic cable/cables coming from the remote side, and in the front side are SC/APC adaptors and
SC/APC jumpers to the Modular Base Units.
6.
The fiber contractor splices fiber cable to the SC/APC connectorized pigtails. In the
communication room the fiber contractor splices/connects the fiber optic cable/cables coming from
the remote end with SC/APC connectorized pigtails inside the patch panel cabinet. The pigtails
connector will be connected to the SC/APC adaptors on the patch panel (from the inside).
7.
Connect SC/APC jumpers between SC/APC adaptors on the patch panel to the Modular
Base Units. For every optic link (MBU--MRC) there are two fibers – one uplink and one downlink
per service.
8.
Connect BTS/RBS to Modular Base Units via ½” coax cable RG223 or similar with 50Ω
impedance according the RF design (see paragraph optical and RF connections).
9.
In the remote end connect pigtail/jumpers fibers from the splice box to each MRC. One splice
box can support several MRC’s according to the optical design (normally three MRC’s).
10. Connect antennas to Modular Remote Cabinet via ½” or 3/8” or similar coax cable with 50Ω
impedance and N-type male to male.
11. Connect power supply to Modular Base Unit and Modular Remote Cabinet (refer to power
planning). Each Modular Base Unit will be connected with D.C. cables (+, -) directly to the planned
power supply. The MRC’s will be connected to the D.C. cables through D.C. clamping coming
from the communication room.

In a high-rise installation, all MBU’s are placed in the same location. The MBU’s are connected to
the BTS/RBS (see BTS/RBS connection – page 44). An MRC can be located on every floor
according to the RF design. The fiber optic cable runs from the MBU to every floor and terminates
at the splice box located on every three floors of the building. Normally, every splice box connects
three MBU’s. From the splice box, the fiber optic jumpers connect to the associated MRC. From
each MRC, a coax cable delivers the signal to the antenna.

INSTALLATION
Connecting to the Ethernet Line
The connection to the Ethernet line can be accomplished in two different ways:
1. Via local connection, or
2. Concentrated remote location.
The local connection can be made by connecting each MRC located at each floor (in a typical
configuration) to the nearest Ethernet line on the same floor. The RJ45 should be connected by cable
to the nearest Ethernet line. The advantage in this configuration is that one can save on fiber
installation that runs from each floor to a central location to be connected to the Ethernet.
The remote connection can be accomplished by using two WizLans (see next page). These two
components are used to convert Ethernet to a fiber optic signal and vice versa.
The Ethernet signal will be converted to fiber optic signal in the amplifier module and sent via the
fiber optic cables to the second converter located next to the remote Ethernet connection (located in
the communication room of the building).
The following steps should be used to connecting the access point to the Ethernet:
1. The Ethernet to fiber optic converter can be mounted on the wall. Use two screws to
connect the WizLAN (Ethernet to fiber optic converted) to the wall.
2. Connect the fiber optic cables to the WizLAN.
3. Connect the WizLAN to the power adapter. (AC to 5 VDC power supply.)
4. Connect the Ethernet link to the WizLAN.

ALARM MONITORING
6. Alarm Monitoring
The Modular Base Unit has a 25 pin D-type connector that is connected to 4 dry contact relays
(MB4U). Each of the relays indicates the status of the link between the MBU and one of the
MRC’s. This capability provides the status of the optical communications for each service. The
relay connections on the 25pin D-type connector can be connected directly to the BTS alarm
relays and can be monitored from the remote end.
In order to transmit the ModuLite™ system as a “major alarm”, all dry contact pins need to be
connected in a serial (cascade) formation, for Normally Closed alarm. All dry contacts need to be
connected in parallel formation, for Normally Open alarm.

POWER SUPPLY FOR MODULITE™
The power supply that drives the ModuLite™ system can be purchased from Foxcom Wireless.
Four power supply options are available.
7.1. Option One (Remote Power)
In this option the MBU is connected to the power supply via electrical cables. In order to power
the MRC from the power supply, two copper electrical wires running through the building
(separately from the fiber optic cables) supply power to each MRC in parallel. For this
configuration, electrical power calculations need to be made. This option is shown in Figure 29.
7.2. Option Two (Local Powering)
In this option the power supply type is a standalone configuration. Power for both the MBU and
MRC’s will be supplied separately. In this configuration each unit will be co-located with a
power supply. This will not require running long electrical cables.
7.3. Option Three (Built-In Powering)
In this option the power supply type for the MRC’s is A.C. Each MRC will come with a built-in
power supply source. To power the MBU’s, local D.C. power will be used. This will not require
running long electrical cables.

OPTICAL TEST PROCEDURE
8. Optical Test Procedure
This section describes the methods applied to test fiber optic cable’s optical insertion loss and
return loss.
8.1. Fiber Optic Cable Test
Due to the extended distances that analog signal transmissions travel on cable, the major
challenge is to determine the status of the cable.
In order to determine that the cables are functioning, technical personnel need to perform optical
power tests.
The optical power tests covered in this document are:
• Optical insertion loss measurement test
• Optical return loss measurement test
In order to explain the testing procedures, the terms related to these tests need to be explained.
8.2. Fiber Optic Cable – Terms
Fiber optic cable is produced in a variety of formats with different characteristics. The following
terms define the various aspects of fiber optic cable:
• Fiber optic cable
Jacket
Buffer
Fiber
• Optical fiber
Core
Clad
Singlemode
Multimode
• Fiber optic connection

8.2.1. Optical Fiber
Fiber optic cable is described by the amount of fibers contained within.
The cable described by the following terms:
• Glass
• Buffer
• Jacket
GLASS
Glass is the middle fiber in the cable. The data sent over the cable travels through the glass.
BUFFER
The buffer is the plastic coating that covers the fiber optic cable. The buffer protects the glass
from moisture and other damage.
JACKET
The jacket covers the buffer, providing greater protection to the glass.
The fiber consists of:
• Core
• Clad
The central part of a fiber is known as the core, and the material surrounding the core is known
as the clad. The clad has a lower index of refraction than the core, allowing light to be
completely reflected off the surface between the core and the clad. As a result, propagated light
remains entirely within the core. The cross-section of the cable is expressed as the core diameter

followed by the clad diameter. For example, a 9/125 fiber has a core diameter of 9µm and a clad
diameter of 125µm.

OPTICAL TEST PROCEDURE
8.2.2. Connecting Fiber Optic Cable
The following are needed in order to carry out a fiber optic connection:
• Splice
• Connector
SPLICE
A splice consists of cutting the fiber optic cable across the cable’s diameter and combining the
opening with another fiber optic cable.
A splice can be carried out in the following methods:
Fusion – following the splice, the cables are warmed and the two fiber optic cables are melted
together.
Mechanical – following the splice, a hard connection is made between the two fiber optic
cables.
CONNECTOR
In order to add or connect additional fiber optic cable, a connector is used to make the
connection. There are several types of connectors:
• FC/PC
• SC/PC
• SC/APC (used by ModuLite™)
8.2.3. Fiber Optic Cable Bending Loss
When the cable has bends or interior irregularities, then the optical signal becomes weaker,
known as Bending Loss. The sharper the bend, the higher the loss. Such losses increase the
cable’s attenuation.
Note
When installing fiber optic cable, the minimum bending radius needs to be noted in order to
prevent excessive bending of the cable, causing additional loss.
8.2.4. Coupler
Foxcom Wireless Confidential and Proprietary Information
Document No. 43-93-005-05 y
54
ModuLite™ Installation Guide
OPTICAL TEST PROCEDURE
Light from the cable can be split or combined, using a Coupler. Couplers split light with
minimal loss, from one to two fibers or combine light from two fibers into a single fiber.
8.3. Foxcom Wireless System Characteristics
The ModuLite™ system consists of the following characteristics:
• Singlemode fiber
• Wavelength 1310nm
• Fiber Optic Cable Measurement Tests
Cable can be measured through several procedures. This document describes the following tests:
• Optical insertion loss measurement test
• Optical return loss measurement test
These tests are intended to be performed by technical personnel that deal with Foxcom Wireless
systems. Other equipment can be used to perform these tests, however the results have to be the
same as will appear in the fiber optic cable test results table (Table 9) at the end of this
document.
The insertion loss measurement determines whether the optical signal power traveling the cable
length is strong enough to be received by the photo diode, in the receiver. Following the
completion of the insertion loss test, the return loss test determines the optical signal power that
returns to the laser. The return power affects the laser, changing the laser’s base current.
8.3.1. Test Equipment
In order to perform these tests, the following equipment is necessary:
•
•
•
•
•
Light source (for wavelength 1310nm , 0dbm)
Optical power meter
Optical coupler (hosed and connectorized)
Fiber optic jumper
Adapter parts for the cable connectors

ModuLite™ Installation Guide
OPTICAL TEST PROCEDURE
• Connect cable being tested to output connector #3.
• If coupler has two outputs, then make a pigtail at second output.
• If cable is longer than 100 meter, then cable needs to be isolated.
To isolate cable:
•
Find place near test point where winding the cable into a pigtail is possible.
•
Make pigtail.
•
If cable is shorter than 100 meter, then verify that cable is disconnected at end.
•
Measure the return light power (P2), connector #2.
Calculating Return Loss
Calculate the difference between the signals in dB.
(Return loss)dB = (P2)dBm – (P3)dBm + (Lc)dB

8.7. Summary
If the fiber fails in the optical insertion loss or optical return loss tests, then the connector needs
to be cleaned. Connector cleaning is carried out according to a standard cleaning procedure.
Following cleaning, the fiber needs to be tested again. If the failure continues in the fiber
following cleaning, then the technical personnel need to refer to the fiber optic cable
manufacturer’s troubleshooting guide.
If the fiber passes the optical insertion loss and optical return loss tests, then the tested fiber optic
cable is considered suitable for use with Foxcom Wireless equipment.
