1. Summary
With better performance and special fast field testing
function, ST815 adopts advanced technology of exact
light and dealing with technology and to support high
performance light for the field test and the lab
development. It has been an ideal instrument for
maintenance and development of optical network
equipments.
ST815 can be widely used in various kinds of optical
cable testing fields, such as LAN, WAN, CAN, CATV and
long-distance Fiber Network.
Together with ST800 series optical power meter, ST815
Laser Source can support stable light signal on many
kinds of wavelength, it can recognize the fiber, test the
fiber loss and continuity accurately, help to evaluate the
transmission quality of fiber chain as well.

7. Advertent Items
Attention: The light source maybe hurt to eyes,
so it is forbidden that the user looks at the light
output end directly when you operate the
instrument in order to avoid the light burn the eyes.
Note: If you use (9v) dry battery, do not recharge
the battery. That is dangerous!
Please pay attention to the followings in order to keep
the performance of the instrument and prolong its

Pr
ess " " button to turn the backlight on or off.
When the backlight is on, the sign will display
on the screen, otherwise this sign disappear. If
the backlight is in a closed state, the operation of
any function key will open the 8 seconds’ backlight
besides pressing "start" button.
5, Under-voltage
When the battery voltage is lower than 7.8V, the
power indicator become
, when the battery
voltage is lower than 7.5V, the equipment will
alarm "Low voltage" every 20 seconds. When the
battery voltage is lower than 7.1V, it will be in auto
turn-off state. Lower than 7.2 V should be charged
in time, charging time is about 4 to 6 hours, please
observe the charger, if the charging indicator light
becomes from red to green, which means the
battery is full.
6. When the equipment is not in use, the user should
immediately cover the dust cap to keep the
adapter clean.

1.
On/Off
Press "On" key 2 seconds to start the equipment,
LCD displays operating wavelength, battery
voltage and modulation state. When you open the
ST815, it works on 1310 nm wavelength and
continuous light output state; press "off" key 2
seconds to close the equipment. The system
defaults auto-shutdown, auto shutdown logo
is
displayed on the screen. Open and turn off the
automatic shutdown function: Press "off" button on
the screen, auto-off mark disappear, which

Wavelength switch function
Press "wavelength" button, you can switch
different wavelengths, and LCD screen display the
different output wavelength.
Note: If you want to switch the 1310nm,
1550nm wavelength to 850nm, 1300nm
(ST815C) or 1490nm (ST815B) or 1625nm
(ST815D), do not forget to change the output
adapter.
3. Modulation output
Press the "Mode" button, you can achieve the
modulated light 270Hz, 1 kHz, 2 kHz continuous
light output, at the same time on the LCD screen
