

When you press , CheckActive™shows and the

troubleshooter looks for an optical signal on the fiber. If

there is a singlemode signal stronger than approximately

-29 dBm on the fiber, ACTIVE LINE blinks and the

troubleshooter will not do a test.

WCaution

If ACTIVE LINE blinks, immediately disconnect the

troubleshooter from the fiber. Optical power levels

more than +7 dBm can cause damage to the detector

in the troubleshooter.



When the low battery symbol shows, replace the batteries

soon. See page 1.



The digits show the fiber length in feet, kilofeet, meters,

or kilometers.

The Connector Adapter

You can change the SC connector adapter to connect to LC, ST,

or FC fiber connectors.

How to Clean Connectors

Fluke Networks recommends that you use a mechanical device

to clean connectors. If you do not have such a device, use other

optical-grade supplies to clean connectors. See the Users

Manual.

Use a video microscope, such as the Fluke Networks FI-7000

FiberInspector™Pro, to inspect connectors.

WCaution

To prevent damage to the device and to connectors,

read all instructions and obey all safety precautions

given by the manufacturer of the device you use to

clean connectors.

How to Use a Mechanical Device to Clean Connectors

Protect Connectors

Always put protective caps on connectors that you do not use.

Clean the caps periodically with a swab or wipers and fiber optic

solvent.

About Launch and Receive Fibers

Launch and receive fibers give the troubleshooter a better view

of the first and last connectors in the link. If you do not use a

launch fiber, the troubleshooter cannot detect the loss of the

first connector in the link. If you do not use a receive fiber, the

troubleshooter cannot detect the loss of the last connector in

the link. Also, the reflectance measurement for the first and last

connectors will be inaccurate.

Usually, you do not need to use a launch or receive fiber with

the FIBER ONESHOT PRO tester. But you must use them in these

situations:

•

You must use a launch fiber if you want to detect a loss

incident (such as a connector, splice, or macrobend) in the

first 30 m of the fiber link.

•

You must use a receive fiber if you want to detect the loss

of the last connector in the fiber link.

If you use a launch or receive fiber, it must have a minimum

length of 30 m (98 ft).

When you use launch or receive fibers, be sure to subtract their

lengths from the length measurement to get the actual length

of the fiber you are testing.

How to Use the Troubleshooter

Notes

Always use patch cords that comply with GR-326-CORE

specifications and have a UPC connector at the end you

will connect to the troubleshooter. Other patch cords

can cause unreliable measurements and damage to the

troubleshooter.

Do not use the troubleshooter to do tests on fibers

that have PC connectors. PC connectors cause large

reflections that the troubleshooter shows as the end of

the fiber.

Clean all fiber connectors.

Connect the fiber to the troubleshooter.

Turn on the troubleshooter, then press . The

troubleshooter automatically saves the results.

Note

After you turn on the troubleshooter, it shows

for a short time to show that it operates correctly.

WCaution

If ACTIVE LINE blinks, immediately disconnect the

troubleshooter from the fiber. Optical power levels

more than +7 dBm can cause damage to the detector

in the troubleshooter.

Examples of Measurement Results

The reflectance of the first

connection is -52 dB. The

length of the launch fiber is

130 m.

The end of the link. The

length of the link (without

the launch fiber) is 8463 m.

A bad splice on the fiber at

2450 m caused a reflectance

incident that is larger than

-45 dB (the default limit).

To see the loss

measurement, press .

Incident is the connection to the

troubleshooter.

The result loss of the fiber

(RL) is 2.6 dB.

The receive fiber adds

130 m to the length

measurement.
