OFI-3 / Introduction

1 Introduction

The OFI-3 optical fiber identifier is an inexpensive, portable

instrument designed to identify optical test tones and live

traffic without disconnecting live system. By simply

clamping the OFI-3 onto a fiber, the instrument will indicate

if there is a signal, or traffic and show the signal direction. It

can detect a variety of optical tones, 270Hz, 1KHz and

2KHz.

The OFI-3 is recommended for both 0.25 mm bare fiber,

0.9mm tightly buffered fiber and 2/3mm jacket fiber. When

testing jacket fibers, the slim design of the OFI-3 allows

easier access to a splice tray where the amount of

workspace is limited. The clamping trigger is designed to fit

the natural motion of the operator’s hand. The instrument is

ruggedly constructed and reliable to use.

OFI-3 / Preparing for Operation

4 Preparing for Operation

4.1 Unpacking the instrument

Packing material

We suggest that you keep the original packing material. Using the original packing material is your

guarantee of protecting the instrument during transit.

Checking the package contents

The standard accessories of OFI-3 are as follows:

Main unit User's Guide

Plungers 2*1.5V Alkaline Batteries

Carrying Case Quality Check Report

Checking for damage in transit

After unpacking the instrument, check to see whether it was damaged in transit. This is particularly likely

if the outer casing is clearly damaged. If there is damage, do not attempt to operate the instrument or to

repair it without authorization. Doing so can cause further damage and you may lose your warranty

qualification.

4.2 Battery

The OFI-3 instrument is powered by two 1.5V AA batteries. There is a “Low” battery indicator on the

panel board. It turns on if there is not enough power to supply the instrument. That is when you should

replace the battery with a new one. To replace the battery, please remove the battery plate on the back

side of the instrument with a screwdriver.

Note: 1 It is advisable to use 1.5V alkaline batteries. The Low Battery Indicator may light up if you use

rechargeable batteries.

2 To eliminate the possibility of acid leakage, please take out the batteries if the unit is not used for a

long time.
