Installation Overview
This chapter provides an overview of the installation procedure for the
Invisible Fiber™ unit (IFU). In addition, this chapter describes the following:

 IFU Link Manager

 Power source

 Cables

 System grounding and surge suppression
Installation Overview
IFUs are loaded with default system attributes at the factory. At the
customer’s designated staging area, the customer-specific attributes identified
in the site database are downloaded to the IFU, which is then ready for
installation. At the installation site, the IFU is installed on a mounting bracket,
aligned, and commissioned. When all installation tests are complete and
expected results are achieved on all IFU sites, the network is ready for
customer acceptance.
Site Engineering Folder
Before installing the IFU, the site must be prepared with the appropriate
cables, demarcation box, and any equipment as detailed in the site
engineering folder. (Refer to the Invisible Fiber™ SONET OC-3 Site
Evaluation Guide for 28 GHz Applications for details about the contents of
the site engineering folder.)
The site engineering folder is referenced throughout this document. Photos
and diagrams of the site are included in the folder.

Installation Overview
IFU Link Manager
The IFU Link Manager is a local element management software application
that helps you configure and commission the IFU. You use this application to
complete the following procedures:

 IFU configuration

 Antenna alignment
Power Source
The IFUs require a – 48 Vdc power source. The specifications of the power
source are defined in the site engineering folder.
Cabling
IFU installations require the following two types of cables:
Power
The power cable connects the IFU to the – 48 Vdc power source.
Fiber Optic
The fiber optic cable connects the IFU to the site equipment cabinet.
Power Cable
The power cable is outdoor/indoor rated. The power cable contains four
12-AWG conductors.
Fiber Optic Cable
For SONET networks, the IFU requires a multi-mode and single-mode fiber
optic cables (see Figure 1-1).

System Grounding and Surge Protection
System Grounding and Surge Protection
The IFU grounding system has two conceptually distinct, but electrically
interconnected functional subsystems, for connection to “earth ground.” The
two functional subsystems are:

 Earth ground (complies with the National Electrical Code (NEC) for
equipment grounding systems).

 Surge protection.
Earth Ground
The IFU has an external electrical interconnection point for connecting the
IFU ground subsystems to earth ground.
Surge Protection
The sole purpose of surge protection is to transport lightning-related currents
to the earth ground. During site installation, surge suppression devices are
installed in line with the power and alarm conductors to assist in protecting
equipment.

The mounting locations must allow the IFU to obtain clear line of sight to the
far-end IFU.
3-4
© 1999 Triton Network Systems, Inc. All Rights Reserved.
Installing IFU Components
To determine the mounting location and method:
With the building manager, define the mounting location and method
(wall mount or pole mount).
NOTE: The preferred mounting location is on a wall because it is
generally structurally sound. The IFU’s streamlined exterior is
designed to complement building aesthetics.
After defining the mounting location for the IFU, re-verify the line of
sight.
For wall- and pole-mount criterians, the bottom of the IFU should be at
least eight feet above the roof.
Wall-Mount Criteria
Wall mounting can be on a parapet wall, screen wall, or penthouse wall that
meets the following criteria:

 The wall must be structurally capable of supporting at least 80
pounds, plus the wind loading as required by the local building codes.

 The wall must allow through-hole bolt mounting.

 The space for the IFU, its mounting bracket, and the alignment area
must be at least 65 inches by 65 inches by 30 inches (W x H x D).
Pole-Mount Criteria
The pole can be attached to the wall or free-standing.
If the pole is attached to a wall, the pole must be structurally capable of
supporting at least 80 pounds, plus the wind loading as required by the local
building codes.
For free-standing poles, calculate the amount of ballast based on the
building’s wind loading requirements. Consult the pole manufacturer for the
required ballast weight to secure the free-standing pole.
NOTE: The total weight of the pole with the IFU can
be upwards of 550 pounds. Consult the pole
manufacturer for the required weight for the ballasts to
secure the free-standing pole roof space required.

des câbles sont destinées exclusivement aux entrepreneurs
agréés et aux préposés à l’entretien de l’immeuble.
Route the IFU power cables to a surge suppression assembly according to
the site drawing.
NOTE: Allow an extra three-foot service loop at the IFU and
twelve inches at each surge suppressor. Use large radius
bends to avoid kinking the cables during the cable routing.
NOTE: Connect the cable shields to the suppressor
mounting panel. Trim the shield back to the cable breakout
and keep the shield as short as possible.
Trim each cable to the appropriate length.
Strip each cable wire to 3/8 inch and tin.

Mounting the IFU Bracket
Installing the Fiber Optic Cable
There are two fiber optic cable routes as follows:

 The IFU Alpha fiber optic cable runs from the IFU mounting location
to the demarcation box.

 The IFU Beta fiber optic cable runs from the IFU mounting location
to the demarcation box.
To install the fiber optic cable:
WARNING: Never touch exposed fiber with any part of
your body. Fiber fragments can enter the skin and are
difficult to detect and remove.
AVERTISSEMENT : Ne jamais laisser une fibre nue
entrer en contact avec une partie quelconque du corps. Des
fragments de fibre peuvent entrer dans la peau, et sont
difficiles à déceler et à enlever.
DANGER: Invisible laser radiation. Avoid direct eye
exposure to the end of a fiber, fiber cord, or fiber pigtail.
The infrared light used in fiber optics systems is invisible,
but can cause serious injury to the eye.
AVERTISSEMENT : Rayonnement laser invisible.
Éviter l’exposition directe des yeux à l’extrémité d’une
fibre, d’un cordon à fibres ou d’une fibre amorce. La
lumière infrarouge utilisée dans les systèmes à fibres
optiques est invisible, mais peut provoquer des lésions
graves aux yeux.
CAUTION: Ensure the outside optical fiber connectors
are environmentally protected. Failure to do so may cause
contamination of the fiber surfaces.
MISE EN GARDE : S’assurer que les raccords extérieurs
fibre optique sont protégés contre l’environnement.
L’absence d’une telle protection peut entraîner la
contamination des surfaces des fibres.

Installation Procedures
CAUTION: To reduce the risk of fiber optic cable
damage, use the following bend radius guidelines for
indoor/outdoor fiber optic cable:

 Long-term (installed): bend radius is equal to 10 times
the diameter of the cable.

 Short-term (during installation): bend radius is equal to
20 times the diameter of the cable.
MISE EN GARDE : Pour réduire le risque de dommage
aux câbles à fibres optiques, suivre les consignes suivantes
en matière de rayon de courbure des câbles à fibres
optiques extérieurs ou intérieurs :

 Courbure à long terme (installée). Le rayon de courbure
ne doit pas dépasser 10 fois le diamètre du câble.

 Courbure à court terme (pendant l’installation). Le
rayon de courbure ne doit pas dépasser 20 fois le
diamètre du câble.
Route the IFU fiber optic cables from each of the IFU mounting locations
to the demarcation box. Refer to the site drawing in the site engineering
folder for the specific route.
NOTE: Allow an extra three-foot service loop at both ends.
Use large radius bends to avoid crimping and kinking the
cables during the cable routing.
