Safety Information
Important Safety Information
WARNING! Useofcontrolsoradjustmentsotherthanthosespeciedhereinmayresult
inhazardousradiationexposure.
The OLS1 optical light source is a CLASS I LED PRODUCT.
WARNING! To avoid the danger of fire and electrical shock:
• NeveruseavoltagethatisdifferentfromthatforwhichtheACadapterisrated.
• Donotplugtheunitintoapoweroutletthatissharedbyotherdevices.
• Nevermodifythepowercordorexcessivelybend,twist,orpullit.
• Do not allow the power cord to become damaged. Do not place heavy objects on
the power cord or expose it to heat.

WARNING! UseonlythespeciedACadapter.UseofanothertypeofACadaptercan
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
orauthorizedagentsforrepairandcalibration.
IMPORTANT! Proper care in handling should be taken when using any precision
optical test equipment. Scratched or contaminated optical connectors can impact the
performance of the instrument. It is important to keep the dust caps in place when the
unit is not being used.

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.
Atestjumpermusthavethesamecoreandcladdingsizeastheberundertest.Theconnector
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 OPM1 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 OPM1 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-ReagentGradeIsopropylAlcohol99%orbetter)andacanoflteredcompressedair.

Section 3: Applications
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
thetestproceduresoutlinedinthisGuide.
Measuring Optical Power
Figure 3-1 illustrates the following procedures.
1 Turn on the OPM1 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 OPM1 optical input. This adapter cap must match
the connector on the end of the test jumper you will connect to the OPM1.
4 Connect one end of the test jumper to the OPM1 (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.
6Read the displayed power measurement (dBm).

Testing Multimode Links
Step I - Set the Reference (One Jumper Method)
Figure 3-2 illustrates the following procedures.
1 Turn on the OPM1 optical power meter and OLS optical light source. Allow the light source to
stabilize(minimumof2minutes).
2 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.
Note:Useopticalwipestocleanbothendsofthetransmitjumper.
5 Connect the transmit jumper to the multimode output port of the OLS.
6 Mount an adapter cap on the OPM1 that matches the free connector on the transmit
jumper.
7 Connect the free end of the transmit jumper to the OPM1. The OPM1 will measure and 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.
9 If the displayed power level is acceptable, record it. This is the reference power level at the

Figure 3-3 illustrates the following procedures.
10 DisconnectthetransmitjumperfromtheOPM1.
Note: DonotdisturbthetransmitjumperattheOLSend.
11 If necessary, change the OPM1 adapter cap to match the connector on the receive jumper
that will be connected to the OPM1.
Note: Useopticalwipestocleanbothendsofthereceivejumper.
12 Connect the receive jumper to the OPM1.
13 Mate the free ends of the transmit and receive jumpers using the appropriate adapter.
14 Record the displayed power level.The difference between the reference power level (from Step
9) and the displayed power level will be the test jumper loss in dB.
Verify that the insertion loss of this mated connector pair is under 0.75 dB, the maximum
allowed by the TIA (Noyes recommends 0.4 - 0.5 dB typical).
If the insertion loss is not acceptable, disconnect the transmit and receive jumpers at the
adapter, clean the free ends of both test jumpers and repeat step 13 & 14.
15 If the insertion loss is acceptable, disconnect the transmit and receive jumpers at the
adapter.
16 Move the OPM1 and OLS to opposite ends of the link to be tested.

Note: Clean jumper end that connects to patch panel prior to every test.
18 Record the displayed power level.The difference between the reference power level (from Step

Battery Replacement
To replace a battery:
1 Remove the protective rubber boot from the instrument.
2 Remove the battery compartment cover located on the back of the instrument.
3 Replace the discharged battery.
4 Replace the battery compartment cover and rubber boot.
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
