Wavelength Specic Optical Testing and Measurement Equipment
This manual contains operation information for the Challenger Cable Sales CO-OTDR Optical Time
Domain Reectometer. This OTDR may be operated by using the touch scree or the on board key
pad. The touch screen is a resistive style screen and only proper stylus devices should be used
when operating the OTDR using the touch screen capability.
This guide is written to instruct operation via the on board keypad. There will be tips throughout
the manual to assist with touch screen operation.
PRECAUTIONS
Optical time domain reectometer are optical instruments that do emit laser radiation
and though this level of radiation is not considered a danger, there are safety
considerations and certain practices that should be followed.
Please read and follow all warning and caution information noted in this manual.
There are warnings, cautions and notes posted throughout this manual.
WARNING
A warning alerts to situations that could cause personal injury.
CAUTION
A caution alerts to situations that may cause damage to the equipment or produce poor
testing conditions resulting in inaccurate test results.
Information contained in this manual is believed to be accurate and reliable. However, no
responsibility is assumed by Challenger Cable Sales for its use nor for any infringements
of patents or other rights of third parties that may result from its use. No license is
granted by implication or otherwise under any patent rights of Challenger Cable Sales.
The information contained in the publications is subject to change without notice.
Chapter 2.0 - Safety / 04
Chapter 3 of this manual is a quick start guide. Prior to using the quick start guide or operating
the equipment in any way, it is highly suggested the user reads all safety information.
The information in this chapter pertains to safety consideration of OTDRs in general.
This product has been designed and tested in accordance with the manufacturer’s safety
standards, and has been supplied in a safe condition.
This document contains information that must be followed by the user to ensure safe operation
and to maintain the product in a safe condition. Failure to follow these safety warnings and
cautions can result in harm to the user or damage to the instrument.
WARNING
Personnel should always be aware when working with ber optic test equipment that
active bers may be present, therefore infrared optical energy may be present.
Never look directly into the end of a connected ber optic cable or ber optic interface
of optical test equipment, to do so could expose the user to laser radiation and could
result in personal injury.
To Prevent Fire or Shock Hazard:
- Do not install battery types other than those specied by the manufacturer
- Do not use the charger without the batteries installed
- Do not expose the battery charger to rain or excessive moisture
- Do not use the AC adapter when there are signs of damage to the enclosure or cord
- Ensure the correct charger is being used for the local line voltage
-Do not use any other charger than the one provided with this instrument.

Chapter 2.0 - Safety / 05
CAUTION
Fiber-optic connectors are easily contaminated or damaged. The connection to the
OTDR is physical contact type of connections and dirty or damaged connectors may
impair the instruments capabilities at minimum and at worst result in the need to return
the OTDR to the factory for expensive repairs. Prior to making any connection to the
unit, ensure that all proper cleaning procedures have been followed. Use UPC Finish
Connectors Only -- DO NOT insert APC connectors into the optical ports.
The OTDR is equipped with a protection circuit to avoid damage from live ber
connections The instrument will not operate properly with active bers. Even with this
protection, high power output from EDFA’s or other equipment can damage detectors
and should never be connected to the OTDR.
If a live ber is connected to the OTDR and a scan is attempted, a warning dialog will
be displayed as in g. 2.1. Immediately remove the live ber from the OTDR and press
select to continue testing.
Failure to follow these cautions statements may void the warranty of, or cause
damage to this equipment.

5.1 OTDR Physical Description
Instrument Enclosure
The CO-OTDR is packaged in a rugged housing which is further protected with a rubberized
boot. Although the front panel is weather resistant, care must be taken to avoid liquids and
contaminants around the fragile optical and electrical connectors, and the glass display. Use a
mild cleaning agent and soft damp cloth to clean up the panels and the outside case. See the
maintenance section to clean the optical connector. NEVER open the instrument for cleaning.
Return to the factory for servicing if necessary.

The cursor is the yellow highlighted area. (If the yellow cursor is on a value that is selected, that
block will be highlighted green) The blue values are the currently selected values. There are
three levels of sensitivity for the event table and Fib-R-Map. The lowest setting possible should
be used to help lter out any events, that may be caused by short pulse widths, but are not true
perturbations in the optical signal

WARNING
Before connecting a patch cord or ber under test, be certain the ber has no active
optical sources or instruments connected to the other end. Skin or eye damage could
result from other high power sources e.g. EDFAs, or instrument damage could occur
voiding the warranty.
Clean connector thoroughly prior to connection to the appropriate port of the OTDR.
Failure to ensure the connectors used with the OTDR are properly cleaned can result in
poor launch conditions at the minimum or damage to the optical interface that requires
the unit be returned to the factory for repair.
6.6 Auto Test
Auto Test is a useful feature when the approximate length of the ber to be tested is unknown.
To use the AutoTest, only the IOR and Wavelength need to be set by the user.
Set IOR
It is necessary to have the Index of Refraction set as close as possible to the actual IOR of the
ber. If this is unknown it is best to use the default setting on the OTDR. To view the current IOR
for a wavelength, open the menu use the left/right button to highlight the IOR Icon. Press select
and the IOR for the wavelength that is the active will be displayed. To change the IOR, use the
on screen QWERTY keyboard to enter the new value and touch save. Each wavelength stores an
independent IOR.
Set Wavelength
To select the wavelength, press the menu button to display the menu at the top of the display.
Use the LRUD buttons to highlight the Lambda (Wavelength) icon, press select to open the page
with available wavelengths displayed. Use the touch screen to select a wavelength or move to
the next page of available wavelengths.
Start Auto Test
Press the AutoTest button and the unit will set the average time to short, the appropriate pulse
width and range parameters for the ber under test.
