Installation Overview

1

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.

28 GHz SONET OC-3 IFU Installation - R1.0 1-1

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 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).

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.

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:

1 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.

2 After defining the mounting location for the IFU, re-verify the line of

sight.

3 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.

FCC 47 CFR 1.1310 requirements) to transmit at below the FCC 47 CFR

1.1310 and Health Canada Safety Code radio frequency maximum
permissible exposure limits (MPE) for controlled/occupational environment
and below the FCC 47 CFR 1.1307 environmental radiation limit, when
installed, operated, and maintained in strict accordance with the product
operating and installation manuals and other materials accompanying the
devices, at any time and under all operating conditions.

Ensure that appropriate warning signs are properly placed and posted at the
equipment site or access entry.

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.

Mounting the IFU Bracket

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.

1 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.

A string of characters entered by a user, typically in a Login window, to gain
access to a computer system.

path loss allowance

The net amount of amplification given to the signal in an IFU link, including
margins for adequate received SNR and channel fading. In other words, path
loss allowance is equal to the system gain plus the antenna gains.

payload

User traffic transported over a network

Point Of Presence (POP)

Umbrella name referring to the location of the physical access point where
user traffic is aggregated.

polarization

Directional orientation of a radio wave electric field. Some radio
communication systems can exploit polarization differences to reduce
interference from nearby links.

POP

See Point Of Presence (POP).

power source

A separate unit or part of a circuit that supplies power to the rest of the circuit
or to a system.
