Unpacking and Inspection

OFI Optical Fiber Identier has been careully packed in accordance with standard shipping

procedures. Examine your OFI or damage that may have occurred during shipment. I you nd

any damage, please contact Noyes.

Feature Overview

Noyes Optical Fiber Identiers are rugged, handheld, and easy-to-use ber optic test instruments

or the installation and maintenance o ber optic networks. The OFI models have been designed

to discriminate optical signals transmitted through a single-mode ber when perorming routing

and general installation, routine maintenance procedures, rerouting, or restoration.

Noyes Optical Fiber Identiers can locate specic bers rom a bundle without disrupting normal

service within a Central Oce (CO), at the splice point, or the Controlled Environmental Vault

(CEV).

The loss induced in the ber during testing is limited, thus service is not interrupted. This method

iscommonlyreferredtoasLocalDetection(LD).ThetwomostwidelyusedLDtechniquesare

macro-bending and micro-bending o the ber. The macro-bending technique, which oers several

advantages over micro-bending, is the technique used in the OFI 200 and OFI 400 design.

By simply clamping an Optical Fiber Identier onto a gently banded ber, the unit will indicate i

there is [NO SIGNAL], [TONE], or [TRAFFIC] and identiy signal direction.

The OFI 200 and OFI 400 are designed specically or single-mode bers carrying 1310 and

1550 nm signals. All specications indicate perormance on a single-mode ber.

Recommended Accessories

When using the OFI 200 or OFI 400 or ber identication, a light source capable o generating

a modulated [TONE] signal is required. The procedure o using a light source in conjunction with

an optical ber identier or ber identication is reerred to as [toning out the ber]. Noyes laser

sources, models OLS 2 and OLS 4, provide multiple Tone generation and may be used or [toning

is 1550 nm.

Section 2: Functional Description

OFI 200 Model Features

The OFI 200 is powered by a standard 9 volt alkaline battery that typically provides over 10,000

operations. Power is controlled by the clamping trigger located on backside o the instrument.

The OFI 200 operates only when the trigger is engaged. This ensures extended battery lie and

minimizesambientlightinuence.

The ber under test is placed in the ber groove and depressed into the optical assembly by

gently pulling the clamping trigger. The OFI 200 will turn on when the plunger is closed and the

ber is in the appropriate position.

Once the plunger is closed, the appropriate indicator [TRAFFIC], [TONE], or [NO SIGNAL] will

illuminate to indicate an optical signal detection. An audible tone generator will beep when the

unitisenergizedandwillproducecontinuoussoundwhena[TONE]signalisdetected.The[Low

Battery] indicator will illuminate when a standard 9V alkaline battery requires replacement.

OFI 400 Model Features

The OFI 400 model is powered by standard 2 x 1.5V alkaline batteries that typically provide over

10,000 operations. Power is controlled either by pressing the [Power] key located on the ront

panel o the instrument or by pulling the trigger all the way down. To ensure extended battery lie,the OFI 400 will turn [O] ater 4 minutes o inactivity. To disable this [Auto O] eature, press

remain [On] until the [Power] key is pressed to turn it [O] .

The ber under test is placed in the ber groove and depressed into the optical assembly by gently

pulling the clamping trigger. The OFI 400 will start taking measurements when the plunger has

closed and the ber is in the appropriate position.

Once the plunger is closed, the appropriate indicator [LEFT], [RIGHT], or [NO SIGNAL] will illuminate

Section 3: Operating Instructions

Precautions

It is important that the precautions given below be ollowed to ensure operating eciency and to

prevent inducing excessive signal loss during testing.

All optical test equipment should be kept ree o dirt and other contaminants. The OFI models

utilizeanopticalassembly,whichmustbekeptfreeofdirtandgrease.RefertoSection4for

cleaning inormation.

The OFI models head assembly is designed to guide the ber being tested to a precise positionrelative to the optical assembly. The user should be careul to place bers gently and in the provided

ber groove. Forcing the ber into the head assembly or misaligning the ber may induce optical

losses above specications.

Note: Bright ambient room or outdoor light can cause the OFI to give alse [TRAFFIC]

readings when testing dark bers. To be sure that the ber is carrying live trac, shield

the optical assembly area o the OFI with your hand as shown in Figure 3-1. Bright ambientlight cannot cause alse [NO SIGNAL] readings; however, low level trac signals in color-

coated ber may not be detected.

Important: The OFI models will not alsely indicate [TONE]. Thereore, only bers identied

as carrying a [TONE] signal should be cut.

Identiying Tone on Fibers

Duringinstallations,maintenance, rerouting, orrestorations it isoftennecessaryto isolate a

specic ber rom a bundle without disrupting service. By simply clamping the OFI 200 or OFI 400

onto a ber beore making any cuts, the identier will indicate i there is [TRAFFIC], [TONE],or [NO SIGNAL] and display the detected [TRAFFIC] signal direction. An audible tone generator

willbeepwhentheunitisenergizedandwillproducecontinuoussoundwhena[TONE]signal

is detected.

Usedinconjunctionwithalightsourcecapableofgeneratingamodulated[TONE]signal,the

OFI 200 and OFI 400 will isolate the ber carrying the [TONE] rom service bers and dark bers.

The procedure o using an optical laser source in conjunction with an optical ber identier orber identication is reerred to as [toning out the ber]. To isolate the ber carrying the [TONE]

signal, perorm the ollowing procedures.

Identiying Tone with OFI 400 Model

1 Connect an optical laser source producing a [TONE] signal to the ber to be tested.

2 Turn on the OFI 400 by pressing the [Power] button.

3 Place the ber to be tested in the ber groove.

4 Pull down and hold the clamping trigger to depress the ber under test into the optical

assembly.

5 When a [TONE] signal is detected, the OFI 400 will produce the continuous beep signal and

show the [TONE] requency value on the display.

Important: The displayed level measurements (dBm) on the OFI 400 are strictly

dependent upon the amount o signal striking the photodiodes in the detector head. Lightreaching the detector head is dependent on ber coating color, coating thickness and

Testing Ribbon Fibers (OFI 200/ OFI 400)Ribbon ber is typically comprised o 4, 8, or 12 bers with a 250 m coating attached together.

The OFI models can test ribbon ber; however, the user should be aware o the limitations. The

OFI models do not isolate a specic ber rom the group in a ribbon. I the ribbon being tested is

carrying a [TONE] signal on one ber and service - [TRAFFIC] signal on any o the other bers in

the group, the OFI will only identiy the ribbon as carrying a [TONE] signal and no [TRAFFIC] will

beindicated.Duetodetectorpositioningandtoensureaccuratereadings,itisrecommendedtofip ribbon ber to test both sides.

Caution: When testing ribbon ber, which is not carrying a [TONE] signal, the OFI Optical

Fiber Identier could possibly give alse [NO SIGNAL] identication i two service bers

in the ribbon are carrying equal power in opposite directions. The signals will cancel one

another resulting in a alse reading.

Veriying OFI Perormance

To veriy perormance o an Optical Fiber Identier, use an optical jumper and a light source

capable o generating both the [CW] signal and the modulated [TONE] signal. When the light

source is transmitting in the [CW] mode, the OFI should indicate [TRAFFIC] in the proper direction.

Switching the light source to the [TONE] mode should activate the OFI audible beeper and indicate

the [TONE] detection as ollows:

Notes:

1 250 m coated ber parameters are specied with OFI 400 plunger in the [250/900/RIB]

position. 2 mm/ 3 mm jacketed ber parameters are specied with OFI 400 plunger in the

[2 mm/ 3 mm] position.2 Unless notedotherwise, all specications are typical.Actual results can vary by several dB

depending on ber type, coating material, jacket color, jacket hardness, and other actors.

All specications stated above are as measured at 25C.

3 [CW] or Continuous Wave is a light signal that is not modulated. [TRAFFIC] is a light signal

modulated by a random data sequence. [TONE] is a light signal modulated into a nominal 50%

duty cycle square wave.Specications are subject to change without notice
