Safety Information
Important Safety Information
WARNING! Use of controls or adjustments other than those specied herein may
result in hazardous radiation exposure.
The CSS1-MM light source is a CLASS I LED PRODUCT.
The CSS1-SM light source is a CLASS I LASER PRODUCT.
CAUTION! To avoid serious eye injury, never look directly into the optical outputs of
ber 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 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.

Recommended Accessories
You will need ber optic test jumpers to connect instruments to the ber optic system under test.
A test jumper must have the same core and cladding size as the ber 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 ber optic system under test.
A Connector adapter is required to mate ber optic test jumpers.
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 light sources, test jumpers, and in ber frames or adapters,
use optical quality cleaning uid such as AFL FCC2 connector cleaning uid and AFL CCT molded
cleaning tips.
For cleaning an optical power meter port and adapter caps, use lint-free optical cleaning wipes
such as AFL FiberWipes and optical quality cleaning uid such as AFL FCC2 connector cleaning
uid (or IPA - Reagent Grade Isopropyl Alcohol 99% or better) and a can of ltered compressed
air.

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 the test procedures outlined in this Guide (see Section titled “Maintenance”
for details).
Measuring Optical Power
Figure 3-1 illustrates the following procedures.
1 Turn on the CSM1 optical power meter.
2 Select the appropriate ber optic test jumper. The ber type of this jumper must be the same
as the ber type normally connected to the output being measured.
3 Mount the appropriate adapter cap on the CSM1 optical input. This adapter cap must match
the connector on the end of the test jumper you will connect to the CSM1.
4 Connect one end of the test jumper to the CSM1 adapter cap and the other end to the
optical output to be measured.
5 Press the [l] key to select the calibrated wavelength that matches the nominal wavelength
of the source being measured.
6If the CSM1 is presently measuring loss [dB], press and release the [dB/dBm] key to display
power in [dBm], or press and hold to display power in [µW].

Testing Fiber Links
Step I - Set the Reference (One Jumper Method)
Figure 3-2 illustrates the following procedures.
1 Turn on the CSM1 optical power meter and CSS1 light source. Allow the CSS1 light source to
stabilize (minimum of 2 minutes).
2 Set both instruments to the desired test wavelength.
3 Select the appropriate ber optic transmit and receive test jumpers. The ber type of these
jumpers must match the ber type of the link to be tested.
4 Wrap and secure the transmit jumper ve times around the appropriate diameter mandrel.
Note: Clean both ends of the transmit jumper.
5 Connect the transmit jumper to the CSS1 output port.
6 Mount an adapter cap on the CSM1 that matches the free connector on the transmit jumper.
7 Connect the free end of the transmit jumper to the CSM1. If necessary, press the [dB/dBm]
key to display optical power in [dBm].
8 If measured output power is outside of the normal range (specied by manufacturer), clean
all ber connections or replace the transmit jumper. Repeat steps 5 - 7.
9 To set the reference level at the current wavelength perform the following steps:

The CSM1 should display [0 dB] ± 0.05 dB.
Note: You may press the [Ref/Set Ref] key to display the stored reference level for the
currently selected wavelength.

14
Step II - Verify Test Jumpers
Figure 3-3 illustrates the following procedures.
10 Disconnect the transmit jumper from the CSM1.
Note: Do not disturb the transmit jumper at the CSS1 end.
11 If necessary, change the CSM1 adapter cap to match the connector on the receive jumper
that will be connected to the CSM1.
Note: Clean both ends of the receive jumper.
12 Connect the receive jumper to the CSM1.
13 Mate the free ends of the transmit and receive jumpers using the appropriate adapter.
14 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), as follows:
• Observe the displayed power level. This is the mated connector pair insertion loss of the
test jumpers in [dB].
15 If the insertion loss is not acceptable, disconnect the transmit and receive jumpers at the
adapter.
• Cleanthefreeendsofbothtestjumpers
• Repeat steps 13 & 14.
• If the insertion loss is still not acceptable, replace test jumpers and repeat steps 1-14.

Step III - Measure Link Insertion Loss
Figure 3-4 illustrates the following procedures.
18 Connect the free ends of the transmit and receive jumpers to the link under test.
Note: Clean jumper end that connects to patch panel prior to every test.
19 CSM1 will measure and display the insertion loss of the link under test.
20 Record link insertion loss at the current test wavelength.
21 Repeat steps 18-20 for all links to be tested at the current wavelength.
