FLS 101 Light Source — Controls and Connections
The FLS 101 light source can test fiber optic links by generating the proper wavelength light
for the link under test. The light source can generate multimode 850 nm and 1300 nm
wavelengths, or singlemode 1310 nm and 1550 nm wavelengths. For each mode, (SM or
MM), the two wavelengths can be generated one at a time or alternating between the two.
NOTE: The light source can only emit light from one output port at a time.
In WAVE ID mode, the light source emits a signal with the light allowing the FPM 101 fiber
power meter to automatically determine the wavelength.

Testing Fiber Optic Links
Multimode or singlemode links are easily measured using the FPM 101 power meter and
FLS 101 light source. Two reference cables, transmit and receive, are required. Before an
unknown fiber link can be measured, the insertion loss of the two reference cables must first
be verified to be less than 0.75 dB.
Test the Transmit Reference Cable:
1. Turn on the FPM 101 power meter and FLS 101 light source. Allow the light source to
stabilize for a minimum of two minutes prior to taking measurements.
a. When using the WAVE ID feature, the FPM 101 power meter reads the wavelength
automatically.
b. If not using WAVE ID, set the FPM 101 to the same wavelength as the FLS 101, (see
3. Select and prepare the transmit reference cable. The fiber type of the reference cable
must match the fiber type of the link to be tested.
a. MM: Wrap and secure the reference cable five times around the included mandrel.
b. SM (TIA testing only): Form and secure a 1.2 inch (30 mm) diameter loop in the
reference cable.
NOTE: Clean both ends of the transmit reference cable before proceeding.
4. Connect the transmit reference cable to the FLS 101 output port (MM or SM).
5. Mount an adapter cap on the power meter. The adapter cap must match the free
connector on the transmit reference cable.
6. Connect the free end of the reference cable to the FPM 101. If necessary, press the

NOTE: Clean reference cable and link ends prior to each test.
3. Observe the displayed values. The link cable insertion loss is displayed in dB.
NOTE: If either the light source or power meter has shut off, turn it back on
and allow to stabilize for a minimum of two minutes.
The two examples in figure 10 below show a multimode and singlemode fiber link being
tested using dual WAVE ID. The insertion loss is displayed in dB.
In the multimode example, the FLS 101 is transmitting both 850 nm and 1300 nm
wavelengths. The FPM 101 has automatically detected the wavelengths using WAVE ID
and is reading a 3.65 dB loss for the 850 nm and 4.07 dB for 1300 nm.
The singlemode example, also using dual WAVE ID, is reading a 1.45 dB loss for the
1310 nm wavelength and 1.49 dB for 1550 nm.

Using the Tone Generator
The tone generator is used for fiber identification when an installer is faced with multiple
unmarked links and the cable ends are not readily accessible by a single technician or are far
removed from one another. The tone is inserted by the light source at one end of the link
and identified at the other using the tone feature of the FPM 101.
In new installations, the link ends can be identified with the FLS 101 and FPM 101 using the
WAVE ID feature and simply looking for the active link among the inactive links. However,
in larger bundles that may have links carrying live data traffic, the tone generator in the
FLS 101 can be used to identify spare links. The FPM 101 can differentiate between live
traffic on fibers and the 2 kHz test tone generated by the FLS 101 to ensure a live fiber is not
cut or disconnected causing a disruption of critical services.
To Quickly Identify a Fiber Optic Link
1. Connect the light source to one end of the link to
be identified. Use the appropriate reference cable
and coupler.
2. Select the 1550 nm wavelength using the SM
button, then turn on the 2 kHz tone by pressing
the tone button. The tone indicator LED lights.
3. On the other end of the link, if the bulkhead is
not accessible, unplug the cables one at a time
and connect them into the receive reference cable
using a coupler. The cable that causes the 2000 Hz
display to light is the desired cable.
NOTE: Cables with live data traffic are identified by their
wavelength and signal strength but they do not light
the tone display.
Identifying wavelengths is not instantaneous. Always
wait a few moments for the FPM 101 to identify the
signal.

Cleaning Optical Ports
CAUTION: Before conducting the following procedures be certain the instruments are turned
Off. Disconnect the external supply from the FLS 101.
Optical ports must be kept free from dirt or other contaminants to ensure accurate
measurements and operation. Always clean reference cables 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 the FLS 101 light sources, test reference cables, and in
fiber frames or adapters, use optical quality cleaning fluid and molded cleaning tips.
For cleaning the FPM 101 optical ports and adapter caps, use lint-free optical cleaning wipes
and optical quality cleaning fluid such as IPA -Reagent Grade Isopropyl Alcohol 99% or
better) and a can of filtered compressed air.
Cleaning FPM 101 Optical Ports
1. Unscrew the adapter cap from the adapter cap mount.
2. Use lint-free optical cleaning wipes and optical quality cleaning fluid and dampen a
portion of the wipe with the cleaning fluid.
NOTE: If using isopropyl alcohol (IPA), be sure to use 99% pure IPA that has not
been contaminated.
3. Gently wipe the exposed FPM 101 port starting with the wet section of the wipe and
pulling it to the dry section.
NOTE: Starting with wet cleaning and finishing with dry improves cleaning action,
reduces static buildup, and leaves the end-face dry.
4. Using a can of filtered compressed air (held vertically), blow out any contaminants from
the adapter cap.
5. Once the cleaning is complete, replace the adapter cap.

Cleaning FLS 101 Optical Ports
1. Rotate the adapter base counterclockwise approximately four times.
2. Pull the adapter directly out and away from the adapter mount.
3. Dampen an optical wipe with alcohol and gently wipe the exposed ferrule.
NOTE: Be certain to use 99% IPA that has not been contaminated.
4. Dry the ferrule using a new optical wipe.
5. Using a can of filtered compressed air (held vertically), blow out any remaining
contaminants from the adapter.
6. Replace the adapter making sure the alignment pin on the adapter aligns with the
mating hole on the base.

Mandrels for Multimode Transmit Reference Cables
When testing multimode links using an overfilled LED source, always wrap the transmit
reference cable five (5) times around the proper diameter mandrel. This is specified by
TIA/EIA-568-B and improves insertion loss measurement repeatability and accuracy. Do NOT
use mandrels on multimode receive reference cables or singlemode reference cables.
