1 Introduction
The FHS1D series mini-sized dual-wavelength laser
sources offer excellent stability and portability for
accurate fiber optic testing. Single output port provides
stable laser power at dual-wavelength. The compact unit
operates in either continuous wave (CW) mode or
modulated mode. A low battery indicator reminds the user
of replacing the battery.
Main Features:
Single output, providing with CW and modulation of
270Hz, 1kHz and 2kHz
Supply with backlighting, 4pcs of AAA battery, LCD
screen and auto-off at the low-battery capacity

3 Safety Information
Warnings!
Never look directly into optical outputs or a fiber while the equipment is on.
Invisible laser beam may damage your eyes.
Do not short-circuit the terminal of AC adapter / charger and the batteries.
Excessive electrical current may cause personal injury due to fumes,electric
shock or equipment damage.
Do not operate the equipment near hot objects, in hot environments, in dusty/
humid atmosphere or when condensation is present on the equipment. This
may result in electric shock , product malfunction or poor performance.

4 Preparing for Operation
4.1 Unpacking the instrument
Packing material
We suggest that you keep the original packing material. Using the original packing
material is your guarantee of protecting the instrument during transit.
Checking the package contents
The standard accessories of FHS1D02/03 are as follows:
5
Main unit
Quality Check Report
4pcs of AAA Battery
Carrying Case
User's Guide
FC/PC(ST/PC, SC/PC optional)
Checking for damage in transit
After unpacking the instrument, check to see whether it was damaged in transit.
This is particularly likely if the outer casing is clearly damaged. If there is damage,
do not attempt to operate the instrument or to repair it without authorization. Doing
so can cause further damage and you may lose your warranty qualification.
FHS1D02/03 / Preparing for Operation

4.2 Power Supply
The instrument is power supplied by 4pcs of AAA battery ,and when you use the
battery, the battery indicator on the screen will show the remaining charge. An empty
battery indicator means the power is almost out. When the battery charge is
extremely low to supply the necessary power, the instrument will automatically switch
off . Please change the battery.

5.6 Connecting with Optical Power Meter
Connecting with FHP1 series optical power meter, FHS1 series dual-wavelength laser source can
make accurate measurement of the fiber loss at the largest distance of more than 300km(@1550).
On-the-spot measurement will differ with the working wavelength, fiber attenuation and the testing
environment.

7 Maintenance
Please cover the protective dust cap once you finish using
It is a good idea to clean the connector and the instrument when they get
dirty through use. Optical cleaning pads and anhydrous alcohol is
recommended. And please be careful not to get the detergent inside the
instrument.
To ensure the measurement accuracy, please send the instrument to
Grandway Service Center for calibration once a year.
