!
WARNING! To avoid the danger of fire and electrical shock:
• Never use a voltage that is different from that for which the AC adapter is rated.
• Do not plug the unit into a power outlet that is shared by other devices.
• Never modify the power cord or excessively bend, twist, or pull it.
• Do not allow the power cord to become damaged. Do not place heavy objects on the power
cord or expose it to heat.
• Never touch the AC adapter while your hands are wet.
• Should the power cord become seriously damaged (internal wiring exposed or shorted),
contact the manufacturer to request servicing.
!
WARNING! Use only the specified AC adapter. Use of another type of AC adapter can damage
the instrument and create the danger of fire and electrical shock.
!
CAUTION! To avoid serious eye injury, never look directly into the optical outputs of fiber optic
network equipment, test equipment, patch cords, or test jumpers. Always assume that optical
outputs are on.
!
NOTICE! Noyes power meters and light sources contain no user serviceable parts. Except
for changing batteries and cleaning optical ports, these units must be returned to Noyes or
authorized agents for repair and calibration.
IMPORTANT! Proper care in handling should be taken when using any precision optical test

General Information
Introduction
The purpose of this User’s Guide is to explain how to use and maintain Noyes test equipment. Please
check our web site at www.AFLtele.com/go/Noyes for updates to this manual, software updates, and
additional application information. If you have any questions about your instruments and recommended
accessories, or if you need technical or sales support, please contact Noyes Customer Service.
Contacting Noyes Customer Service
You may call Noyes Customer Service between 8 a.m. and 5 p.m., United States Eastern Time, as follows:
Phone: 800-321-5298 • 603-528-7780
Fax:
603-528-2025
Email: [email protected]
Unpacking and Inspection
These instruments have been carefully packed in accordance with standard shipping procedures. Examine
the equipment for damage that may have occurred during shipment. If you find any damage, please
contact Noyes.
Recommended Accessories
You will need fiber optic test jumpers to connect instruments to the fiber optic system under test. A test
jumper must have the same core and cladding size as the fiber under test. The connector at one end of
the test jumper must mate with the optical port on each instrument. The connector on the other end must
mate with the fiber optic system under test.
A Connector adapter is required to mate fiber optic test jumpers.
An OPM optical port must be equipped with an adapter cap. A variety of adapter caps, connector
adapters, and test jumpers with a variety of lengths and connector styles are available from AFL - Noyes.
Optical ports and connector end faces must be kept free from dirt or other contaminates to ensure
accurate measurements and operation.
For cleaning connector end faces on OLS light sources, test jumpers, and in fiber frames or adapters, use
optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid and AFL CCT molded cleaning
tips.
For cleaning OPM optical ports and adapter caps, use lint-free optical cleaning wipes such as AFL
FiberWipes and optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid (or IPA - Reagent
Grade Isopropyl Alcohol 99% or better) and a can of filtered compressed air.
Visit our web at www.AFLtele.com/go/Clean for more information.

8. Output Adjust keys - The ∆ and ∇ arrow keys allow entering the Output Adjust mode and changing
the power level currently being transmitted at the output port within approximately 3 dB power range
between the factory preset maximum and minimum power levels.
∆ arrow key increases the optical output power up to the allowed maximum level.
∇ arrow key decreases the optical output power down to the allowed minimum level.
Output Adjust Mode Characteristics
a) The Output Adjust mode is valid in CW and single WAVE ID modes only.
Note:
•• If the Output Adjust mode is enabled while the OLS2-Dual is transmitting Dual WAVE ID, the
unit will switch to the 1310nm WAVE ID mode.
•• If the Output Adjust mode is enabled while the OLS2-Dual is transmitting any of the Tone
frequencies, the unit will switch to the CW mode.
b) To enable the Output Adjust mode and begin power change, perform the following steps:
•• Hold either the ∆ or ∇ arrow keys for approximately 4 seconds.
•• An Active Mode indicator of the currently enabled mode (CW or WAVE ID) will turn ON blinking light at approximately ½ second rate.
•• The optical output will begin to change correspondingly to the currently pressed key. ( ∆ key increase output power, ∇ key - decrease output power).
c) Key functions while in the Output Adjust mode are indicated below:
•• Mode key - -toggles between single WAVE ID and CW mode.
•• Wavelength key - toggles optical output between 1310 & 1550 nm.
•• ∆ or ∇ arrow key - increases or decreases the optical output power level.
d) The Output Adjust Mode is automatically disabled after approximately 8 seconds with no key
presses. The OLS2-Dual will return to its previous operating mode it was in prior to entering the
Output Adjust mode.
Output Adjust Mode Operation
To adjust the output power, perform the following steps:
21
OLS2-Dual Laser Source
a) Press and hold either ∆ or ∇ arrow key for ~. 4 seconds to enable the Output Adjust mode.
b) When the OLS2-Dual enters the Output Adjust mode, an Active Mode indicator of the currently
enabled mode (CW or WAVE ID) turns ON - blinking light, the Output Adjust mode is enabled. The
currently selected output can now be adjusted.
c) Press the ∆ or ∇ arrow key to increase or decrease the current power level.
•• Press momentarily to adjust the optical output in a small step.
•• Press and hold to adjust in small steps for a total of six steps at a rate of ~. 2 steps per
second. Continuing to press the same arrow key will cause the unit to increase step size to
and continue at the same repetition rate. Releasing the held key at any time resets the step
size to small and resets the “step size counter” to zero.
Note: End of adjust range indication - Noyes recommends using an Optical Power Meter to
monitor the output when adjusting the OLS2-Dual power level. However, this is not necessary to
set the OLS2-Dual to the maximum or minimum output level. When the end of the adjustment
range has been reached, the OLS2-Dual will turn off the Active Mode Indicator and blink the
Active Output indicator at a rate of approximately 1/4 second. Releasing the arrow key restores
the LED Indicators to their previous states.

Measuring Optical Power
It is important to keep all optical connections and surfaces free from dirt, oils, or other
contaminants to ensure proper operation. Always clean all test jumpers before conducting the
test procedures outlined in this Guide (see Section 5: “Maintenance” for details).
!
To Measure Optical Power
1. Turn on the OPM optical power meter.
2. Select the appropriate fiber optic test jumper. The fiber type of this jumper must be the same as the
fiber type normally connected to the output being measured.
3. Mount the appropriate adapter cap on the OPM optical input. This adapter cap must match the
connector on the end of the test jumper you will connect to the OPM.
4. Connect one end of the test jumper to the OPM adapter cap and the other end to the optical output to
be measured.
5. Press the λ key to select the calibrated wavelength that matches the nominal wavelength of the
source being measured.
6. If the OPM is presently measuring loss dB, press the dB/dBm key to display power in dBm, or press
and hold to display power in µW.
7. OPM5 power meters only: You may press the Store key to save the displayed measurement in the
next available memory location.

(minimum of 2 minutes).
2. If not using the WAVE ID feature, set both instruments to the desired test wavelength.
3. Select the appropriate fiber optic transmit and receive test jumpers. The fiber type of these jumpers
must match the fiber type of the link to be tested.
4. Wrap and secure the transmit jumper five times around the appropriate diameter mandrel.
Clean both ends of the transmit jumper!
5. Connect the transmit jumper to the multimode output port of the OLS.
6. Mount an adapter cap on the OPM that matches the free connector on the transmit jumper.
7. Connect the free end of the transmit jumper to the OPM.
If necessary, press the dB/dBm key to display optical power in dBm.
8. If measured output power is outside of the normal range (specified by manufacturer), clean all fiber
connections or replace the transmit jumper. Repeat steps 4 - 7.

Step III - Measure Single-mode Link Insertion Loss
17. Connect the free ends of the transmit and receive jumpers to the single-mode link under test.
Clean jumper end that connects to patch panel prior to every test!
18. OPM will measure and display the insertion loss of the link under test.
19. Perform one of the following:
If using OPM4: Record link insertion loss at the current test wavelength.
If using OPM5: Press the Store key on the OPM5 to save the displayed measurement in the next
available memory location.
20. Repeat steps 17-19 for all links to be tested at the current wavelength.

Maintenance Tips
Cleaning Optical Ports
CAUTION! Before conducting the following procedures be sure to have the instruments turned OFF.
Optical ports must be kept free from dirt or other contaminants to ensure accurate measurements and
operation. Always clean all test jumpers before conducting the test procedures outlined in this Guide. It is
important to keep dust caps in place when instruments are not being used.
For cleaning connector end faces on OLS light sources, test jumpers, and in fiber frames or adapters, use
optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid and AFL CCT molded cleaning
tips.
For cleaning OPM optical ports and adapter caps, use lint-free optical cleaning wipes such as AFL
FiberWipes and optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid (or IPA -Reagent
Grade Isopropyl Alcohol 99% or better) and a can of filtered compressed air.
Cleaning OPM Optical Ports
1. Unscrew the adapter cap from the adapter cap mount.
2. Use lint-free optical cleaning wipes such as AFL FiberWipes and optical quality cleaning fluid such as
AFL FCC2 connector cleaning fluid.
Note: if using isopropyl alcohol (IPA), be sure to use 99% pure IPA that has not been contaminated.
•• Dampen a portion of the wipe with the cleaning fluid.
•• Gently wipe the exposed OPM port starting with the wet section of the wipe and pulling it to the
dry section.
Note: Starting with the wet cleaning and finishing in the dry improves cleaning action, reduces static
buildup, and finishes with the end-face dry.
3. Using a can of filtered compressed air (held vertically), blow out any contaminants from the adapter
cap.
4. Replace the adapter cap once the cleaning is complete.
Cleaning OLS Optical Ports without removing adapters
AFL One-Click Cleaner method
1. Remove the protective dust cover from the tip of the One-Click Cleaner.
2. Insert the tip of the One-Click Cleaner into the optical port adapter and gently press the body of the
One-Click Cleaner until an audible “click” is heard.
3. Remove the One-Click Cleaner.
Cleaning OLS Optical Ports with Adapters Removed
1. Rotate the adapter base counterclockwise approximately four times.
2. Pull the adapter directly out away from the adapter mount.
3. Perform one of the following:
AFL FCC2 fluid and CCT stick method
•• Leaning the FCC2 can back (30°), press the button on the FCC2 to fill the well.
•• Dip the CCTP tip into the well of the FCC2 to dampen the tip with optical cleaning fluid.
36
•• Place the damp tip over the ferrule to be cleaned.
•• Rotate the tip clockwise 10 revolutions while applying varying pressure to create a gentle pumping
action where the tip contacts the ferrule.
•• Discard the CCTP stick after using both tips.
If using lint-free optical cleaning pads and isopropyl alcohol
•• Be sure to use 99% IPA that has not been contaminated.
•• Dampen the wipe with the alcohol and gently wipe the exposed ferrule. Then dry the ferrule using
a new optical wipe
4. Using a can of filtered compressed air (held vertically), blow out any contaminants from the adapter.
5. Once completed, replace the adapter making sure that the alignment pin on the adapter aligns with
the mating hole on the base.
Repair and Calibration
Repair of the Noyes test equipment in the field is NOT recommended.
Calibration is recommended every 12 months. Noyes Calibration Department is in compliance with ANSI/
NCSL Z540-1, ISO 10012-1, MIL STD 45662A, ISO Guide 25 and traceability to the National Institute
of Standards and Technology. Call Customer Service to obtain a Service Request (S.R.) number before
sending units in for calibration.
Battery Replacement
To replace a battery:
6. Remove the protective rubber boot from the instrument.
7. Remove the battery compartment cover located on the back of the instrument.
8. Replace the discharged battery.
9. Replace the battery compartment cover and rubber boot.
Mandrels for Multimode Transmit Jumpers
When testing multimode links using an overfilled LED source, always wrap the transmit jumper five (5)
times around the proper diameter mandrel. This is specified by TIA/EIA-568-B and will improve insertion
loss measurement repeatability and accuracy. Do NOT use mandrels on multimode receive jumpers or
single-mode jumpers.
