1. Overview:
FLS-55 - Single-mode & Multi-mode Fiber Optic Light Source:
Provides 850/1300 nm wavelengths (for multi-mode fiber cables) or 1310/1550 nm
wavelengths (for single-mode fiber cables) at varying frequencies for checking the optimal
loss of fiber optic cables using our FPM-50 Fiber Optic Power Meter (or other power
meter).

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: Hold to turn the Handheld Light Source Light On or Off.
(a) While ON, press once to turn off the auto-off feature.
(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-55 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-55 Light Source.
