FLS-50
FIBER OPTIC LIGHT SOURCE
6. Maintenance:
6.1 If the Light Source is not used for a long time, the light output port must be
protected with the dustproof cover.
6.2 When the Fiber Optic Light Source is used for a long period of time, the output port
may get dirty, which results in the output power decreasing. If there is a
noticeable loss in output power, the connector must be cleaned with a cotton swab
and alcohol. If it cannot be cleaned, please send it to the manufacturer for a
replacement.
6.3 If you are not planning to use the (FW-5) Light Source for a long period of time,
remove the batteries to prevent leakage.
6.4 Do not take the Fiber Optic Light Source apart. If there are any other issues, please
contact the manufacturer.
6.5 DO NOT look into the Light Source adapters directly while the light source is on.
The laser output will damage your eyes.
7. Trouble-shooting:
1 The output light is unstable or
decreases rapidly while operation.
Replace the batteries.
2 Output power is fluctuating. Try warming-up the device for 15 minutes,
then use it.
3 The output port is dirty. Clean the connector with a cotton swab and
alcohol.
No. Problem Measures

1. Overview:
FLS-50 - Fiber Optic Light Source:
Provides two different wavelength outputs, 1310 nm or 1550 nm, at varying frequencies
for checking the optimal loss of single mode fiber optic cables using our FPM-50 Fiber
Optic Power Meter (or other power meters).
2. Technical Specifications:
3. What’s Included:

AA 1.5V battery
Storage Bag
Diagram of the FLS-50
Keys and Functions:
(1) Wavelength Output Port: FC/SC/LC.
(2) Liquid Crystal Display: Displays wavelength and frequency of the light emitted.
(3) “ON/OFF” Key: Press to turn the Handheld Light Source Light On or Off.
(4) “Wave” key: For selecting the wavelength emitted.
(5) “Mode” key: Modulation control: CW light output and modulated light output
can be selected by pushing “Mode” key. When modulated light output is selected,
a dot appears on the screen.
5. Operation:
5.1 Press and hold the “ON/OFF” key for about one second to turn on the FLS-50 Light
Source. The default wavelength is 1310nm and can be changed using the “MODE”
key.
5.2 To use the Fiber Optic Light Source:
1. Connection: Choose one of the connectors: FC, SC, or LC, and install it on the
light source. The FC adapter comes preinstalled.
2. Wavelength selection: Press “Wave” key for wavelength selection.
3. Modulation: Press the “MODE” key, choose the “CW”,”270Hz”,”1KHz” or “2KHz”
light output.
4. When Done: Press “ON/OFF” key to turn off the FLS-50 Light Source.
