1 Introduction
The FHS2T01F three-wavelength laser source
offers excellent stability, portability and facile
adjustments for accurate optical fiber testing.
Single output connector serves three
wavelengths, 1310nm,1550nm & 1490nm.
FHS2T01F can be used to test single mode optical
fiber of long distance and local network. Also it can
work with optical power meter to measure the loss
of optical fiber.

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.
Connect DC power cord with the equipment and wall socket properly. While
inserting the DC plug, make sure there is no dust or dirt on the terminals and
both plugs are fully seated. Incomplete engagement may cause fuming,
electric shock or equipment damage and may result in personal injury.
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 FHS2T01F are as follows:
5
Main unit(including battery)
Quality Check Report
DC 6V Adapter
Carrying Case
User's Guide
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.

Connectors(FC/PC,SC/PC)

4.2 Power Supply
There are battery indicator and power plug on the screen to show the power supply.
When you use the DC 6v charger, there is no battery indicator on the screen. When
you do not connect the DC 6v charger, the adapter indicator will disappear on the
screen.
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 after several beeps of the buzzer. Please change the battery
or recharge it

5.2 Turning the instrument on and off
Press the “ON/OFF” key briefly.
The instrument powers on.(See the figure)
Press the “ON/OFF” key briefly again.
The instrument powers off.
Note: Auto-off function
1 The instrument powers off automatically if no key press in 10 minutes.
2 Press the “ON/OFF” key for about 2 seconds to power on the instrument with
"Auto-off" function deactivated.

5.5 Auto-wavelength Recognition
Press the "TWIN" Key to tun on and off the auto-wavelength recognition function.
Note:
1) It is suggested to turn off the "TWIN" code when you do not use it. The optical power output of laser
source will be fluctuated.
2) The function of "TWIN" and Modulation cannot work together. When the "TWIN" is on, modulation of
laser source module is closed automatically.
3) Wavelength will be shifted automatically according to the recognition when the "TWIN" of power meter
module is on. In another word, the modulated signal of 270Hz, 1kHz and 2kHz cannot be recognized and
received at the moment.
